NAME

amanda - Advanced Maryland Automatic Network Disk Archiver
 

SYNOPSIS

DESCRIPTION

Here are all the Amanda commands. Each one has its own manual page. See them for all the gory details.

amdump

Take care of automatic Amanda backups. This is normally executed by cron on a computer called the tape server host and requests backups of file systems located on backup clients. Amdump backs up all disks in the disklist file (discussed below) to tape or, if there is a problem, to a special holding disk. After all backups are done, amdump sends mail reporting failures and successes.

amflush

Flush backups from the holding disk to tape. Amflush is used after amdump has reported it could not write backups to tape for some reason. When this happens, backups stay in the holding disk. Run amflush after the tape problem is corrected to write backups from the holding disk to tape.

amcleanup

Clean up after an interrupted amdump. This command is only needed if amdump was unable to complete for some reason, usually because the tape server host crashed while amdump was running.

amrecover

Provides an interactive interface to browse the Amanda index files (backup image catalogues) and select which tapes to recover files from. It can also run amrestore and a restore program (e.g. tar) to actually recover the files.

amrestore

Read an Amanda tape, searching for requested backups. Amrestore is suitable for everything from interactive restores of single files to a full restore of all partitions on a failed disk.

amlabel

Write an Amanda format label onto a tape. All Amanda tapes must be labeled with amlabel. Amdump and amflush will not write to an unlabeled tape (see TAPE MANAGEMENT below).

amcheck

Verify the correct tape is mounted and all file systems on all backup client systems are ready to be backed up. Often run by cron before amdump to generate a mail warning that backups might fail unless corrective action is taken.

amadmin

Take care of administrative tasks like finding out which tapes are needed to restore a filesystem, forcing hosts to do full backups of selected disks and looking at schedule balance information.

amtape

Take care of tape changer control operations like loading particular tapes, ejecting tapes and scanning the tape storage slots.

amverify

Check Amanda backup tapes for errors.

amrmtape

Delete a tape from the Amanda databases.

amstatus

Report the status of a running or completed amdump.

amoverview

Display a chart of hosts and file systems backed up every run.

amplot

Generate utilization plots of Amanda runs for performance tuning.

amreport

Generate an Amanda summary E-mail report.

amtoc

Generate table of content files for Amanda tapes.

amcheckdb

Verify every tape Amanda knows about is consistent in the database.

amgetconf

Look up parameters in the Amanda configuration file.

CONFIGURATION

All files are stored in individual configuration directories under /etc/amanda. A site will often have more than one configuration. For example, it might have a normal configuration for everyday backups and an archive configuration for infrequent full archival backups. The configuration files would be stored under directories /etc/amanda/normal/ and /etc/amanda/archive/, respectively. Part of the job of an Amanda administrator is to create, populate and maintain these directories.

All log and database files generated by Amanda go in corresponding directories somewhere. The exact location is controlled by entries in amanda.conf. A typical location would be under /var/adm/amanda. For the above example, the files might go in /var/adm/amanda/normal/ and /var/adm/amanda/archive/.

As log files are no longer needed (no longer contain relevant information), Amanda cycles them out in various ways, depending on the type of file.

Detailed information about amdump runs are stored in files named amdump.NN where NN is a sequence number, with 1 being the most recent file. Amdump rotates these files each run, keeping roughly the last tapecycle (see below) worth of them.

The file used by amreport to generate the mail summary is named log.YYYYMMDD.NN where YYYYMMDD is the datestamp of the start of the amdump run and NN is a sequence number started at 0. At the end of each amdump run, log files for runs whose tapes have been reused are renamed into a subdirectory of the main log directory (see the logdir parameter below) named oldlog. It is up to the Amanda administrator to remove them from this directory when desired.

Index (backup image catalogue) files older than the full dump matching the oldest backup image for a given client and disk are removed by amdump at the end of each run.  

CONFIG FILE PARAMETERS

Lines starting with # are ignored, as are blank lines. Keywords are case insensitive, i.e. mailto and MailTo are treated the same.

Integer arguments may have one of the following (case insensitive) suffixes, some of which have a multiplier effect:

b byte bytes

Some number of bytes.

bps

Some number of bytes per second.

k kb kbyte kbytes kilobyte kilobytes

Some number of kilobytes (bytes*1024).

kps kbps

Some number of kilobytes per second (bytes*1024).

m mb meg mbyte mbytes megabyte megabytes

Some number of megabytes (bytes*1024*1024).

mps mbps

Some number of megabytes per second (bytes*1024*1024).

g gb gbyte gbytes gigabyte gigabytes

Some number of gigabytes (bytes*1024*1024*1024).

tape tapes

Some number of tapes.

day days

Some number of days.

week weeks

Some number of weeks (days*7).

The value inf may be used in most places where an integer is expected to mean an infinite amount.

Boolean arguments may have any of the values y, yes, t, true or on to indicate a true state, or n, no, f, false or off to indicate a false state. If no argument is given, true is assumed.

org "string"

Default: DailySet1. A descriptive name for the configuration. This string appears in the Subject line of mail reports. Each Amanda configuration should have a different string to keep mail reports distinct.

mailto "string"

Default: operators. A space separated list of recipients for mail reports.

dumpcycle int

Default: 10 days. The number of days in the backup cycle. Each disk will get a full backup at least this often. Setting this to zero tries to do a full backup each run.

Note that this parameter may also be set in a specific dumptype (see below). This value sets the default for all dumptypes so must appear in amanda.conf before any dumptypes are defined.

runspercycle int

Default: same as dumpcycle. The number of amdump runs in dumpcycle days. A value of 0 means the same value as dumpcycle. A value of -1 means guess the number of runs from the tapelist file, which is the number of tapes used in the last dumpcycle days / runtapes.

tapecycle int

Default: 15 tapes. The number of tapes in the active tape cycle. This must be at least one larger than the number of Amanda runs done during a dump cycle (see the dumpcycle parameter) times the number of tapes used per run (see the runtapes parameter).

For instance, if dumpcycle is set to 14 days, one Amanda run is done every day (Sunday through Saturday), and runtapes is set to one, then tapecycle must be at least 15 (14 days * one run/day * one tape/run + one tape).

In practice, there should be several extra tapes to allow for schedule adjustments or disaster recovery.

dumpuser "string"

Default: amanda. The login name Amanda uses to run the backups. The backup client hosts must allow access from the tape server host as this user via .rhosts or .amandahosts, depending on how the Amanda software was built.

printer "string"

Printer to use when doing tape labels. See the lbl-templ tapetype option.

tapedev "string"

Default: /dev/null. The path name of the tape device. If a tape changer is configured (see the tpchanger option), this option may not be used and should be commented out of the configuration file.

If tapedev is set to /dev/null, amdump will run normally but all images will be thrown away. This should only be used for debugging, and probably only with the record option set to no.

rawtapedev "string"

Default: /dev/null. The path name of the raw tape device. This is only used if Amanda is compiled for Linux machines with floppy tapes and is needed for QIC volume table operations.

tpchanger "string"

Default: none. The name of the tape changer. If a tape changer is not configured, this option is not used and should be commented out of the configuration file.

If a tape changer is configured, choose one of the changer scripts (e.g. chg-scsi) and enter that here.

changerdev "string"

Default: /dev/null. A tape changer configuration parameter. Usage depends on the particular changer defined with the tpchanger option.

changerfile "string"

Default: /usr/adm/amanda/log/changer-status. A tape changer configuration parameter. Usage depends on the particular changer defined with the tpchanger option.

runtapes int

Default: 1. The maximum number of tapes used in a single run. If a tape changer is not configured, this option is not used and should be commented out of the configuration file.

If a tape changer is configured, this may be set larger than one to let Amanda write to more than one tape.

Note that this is an upper bound on the number of tapes, and Amanda may use less.

Also note that as of this release, Amanda does not support true tape overflow. When it reaches the end of one tape, the backup image Amanda was processing starts over again on the next tape.

labelstr "string"

Default: .*. The tape label constraint regular expression. All tape labels generated (see amlabel(8)) and used by this configuration must match the regular expression. If multiple configurations are run from the same tape server host, it is helpful to set their labels to different strings (for example, "DAILY[0-9][0-9]*" vs. "ARCHIVE[0-9][0-9]*") to avoid overwriting each other's tapes.

tapetype "string"

Default: EXABYTE. The type of tape drive associated with tapedev or tpchanger. This refers to one of the defined tapetypes in the config file (see below), which specify various tape parameters, like the length, filemark size, and speed of the tape media and device.

ctimeout int

Default: 30 seconds. Maximum amount of time that amcheck will wait for each client host.

dtimeout int

Default: 1800 seconds. Amount of idle time per disk on a given client that a dumper running from within amdump will wait before it fails with a data timeout error.

etimeout int

Default: 300 seconds. Amount of time per disk on a given client that the planner step of amdump will wait to get the dump size estimates. For instance, with the default of 300 seconds and four disks on client A, planner will wait up to 20 minutes for that machine. A negative value will be interpreted as a total amount of time, instead of a per-disk value.

netusage int

Default: 300 Kbps. The maximum network bandwidth allocated to Amanda, in Kbytes per second. See also the interface section.

inparallel int

Default: 10. The maximum number of backups that Amanda will attempt to run in parallel. Amanda will stay within the constraints of network bandwidth and holding disk space available, so it doesn't hurt to set this number a bit high. Some contention can occur with larger numbers of backups, but this effect is relatively small on most systems.

maxdumps int

Default: 1. The maximum number of backups from a single host that Amanda will attempt to run in parallel. See also the inparallel option.

Note that this parameter may also be set in a specific dumptype (see below). This value sets the default for all dumptypes so must appear in amanda.conf before any dumptypes are defined.

bumpsize int

Default: 10 Mbytes. The minimum savings required to trigger an automatic bump from one incremental level to the next. If Amanda determines that the next higher backup level will be this much smaller than the current level, it will do the next level. See also the bumpmult option.

bumpmult float

Default: 1.5. The bump size multiplier. Amanda multiplies bumpsize by this factor for each level. This prevents active filesystems from bumping too much by making it harder to bump to the next level. For example, with the default bumpsize and bumpmult set to 2.0, the bump threshold will be 10 Mbytes for level one, 20 Mbytes for level two, 40 Mbytes for level three, and so on.

bumpdays int

Default: 2. To insure redundancy in the dumps, Amanda keeps filesystems at the same incremental level for at least bumpdays days, even if the other bump threshold criteria are met.

diskfile "string"

Default: disklist. The file name for the disklist file holding client hosts, disks and other client dumping information.

infofile "string"

Default: /usr/adm/amanda/curinfo. The file or directory name for the historical information database. If Amanda was configured to use DBM databases, this is the base file name for them. If it was configured to use text formated databases (the default), this is the base directory and within here will be a directory per client, then a directory per disk, then a text file of data.

logdir "string"

Default: /usr/adm/amanda. The directory for the amdump and log files.

indexdir "string"

Default /usr/adm/amanda/index. The directory where index files (backup image catalogues) are stored. Index files are only generated for filesystems whose dumptype has the index option enabled.

tapelist "string"

Default: tapelist. The file name for the active tapelist file. Amanda maintains this file with information about the active set of tapes.

tapebufs "int"

Default: 20. The number of buffers used by the taper process run by amdump and amflush to hold data as it is read from the network or disk before it is written to tape. Each buffer is a little larger than 32 KBytes and is held in a shared memory region.

reserve number

Default: 100(percent). The amount of holding-disk space that should not be used for full backups if no tape is available. By default, when there is no tape to write to, degraded mode (incremental) backups will be performed to the holding disk. If full backups should also be allowed in this case, the amount of holding disk space reserved for incrementals should be lowered.

columnspec "string"

Defines the width of columns amreport should use. String is a comma (',') separated list of triples. Each triple consists of three parts which are separated by a equal sign ('=') and a colon (':') (see the example). These three parts specify:

+

the name of the column, which may be:

Compress (compression ratio)
Disk (client disk name)
DumpRate (dump rate in KBytes/sec)
DumpTime (total dump time in hours:minutes)
HostName (client host name)
Level (dump level)
OrigKB (original image size in KBytes)
OutKB (output image size in KBytes)
TapeRate (tape writing rate in KBytes/sec)
TapeTime (total tape time in hours:minutes)

+

the amount of space to display before the column (used to get whitespace between columns).

+

the width of the column itself. If set to a negative value, the width will be calculated on demand to fit the largest entry in this column.

Here is an example:

     columnspec "Disk=1:18,HostName=0:10,OutKB=1:7"

The above will display the disk information in 18 characters and put one space before it. The hostname column will be 10 characters wide with no space to the left. The output KBytes column is seven characters wide with one space before it.

HOLDINGDISK SECTION

holdingdisk name {
    holdingdisk-option holdingdisk-value
    ...
}

Name is a logical name for this holding disk.

The options and values are:

comment "string"

Default: none. A comment string describing this holding disk.

directory "disk"

Default: /dumps/amanda. The path to this holding area.

use int

Default: 0 Gb. Amount of space that can be used in this holding disk area. If the value is zero, all available space on the file system is used. If the value is negative, Amanda will use all available space minus that value.

chunksize int

Default: 1 Gb. Holding disk chunk size. Dumps larger than the specified size will be stored in multiple holding disk files. The size of each chunk will not exceed the specified value. However, even though dump images are split in the holding disk, they are concatenated as they are written to tape, so each dump image still corresponds to a single continuous tape section.

If 0 is specified, Amanda will create holding disk chunks as large as ((INT_MAX/1024)-64) Kbytes.

Each holding disk chunk includes a 32 Kbyte header, so the minimum chunk size is 64 Kbytes (but that would be really silly).

Operating systems that are limited to a maximum file size of 2 Gbytes actually cannot handle files that large. They must be at least one byte less than 2 Gbytes. Since Amanda works with 32 Kbyte blocks, and to handle the final read at the end of the chunk, the chunk size should be at least 64 Kbytes (2 * 32 Kbytes) smaller than the maximum file size, e.g. 2047 Mbytes.

DUMPTYPE SECTION

A set of backup options are entered in a dumptype section, which looks like this:

define dumptype name {
    dumptype-option dumptype-value
    ...
}

Name is the name of this set of backup options. It is referenced from the disklist file.

Some of the options in a dumptype section are the same as those in the main part of amanda.conf. The main option value is used to set the default for all dumptype sections. For instance, setting dumpcycle to 50 in the main part of the config file causes all following dumptype sections to start with that value, but the value may be changed on a section by section basis. Changes to variables in the main part of the config file must be done before (earlier in the file) any dumptypes are defined.

The dumptype options and values are:

auth "string"

Default: bsd. Type of authorization to perform between tape server and backup client hosts. May be krb4 to use Kerberos-IV authorization.

comment "string"

Default: none. A comment string describing this set of backup options.

comprate float [, float ]

Default: 0.50, 0.50. The expected full and incremental compression factor for dumps. It is only used if Amanda does not have any history information on compression rates for a filesystem, so should not usually need to be set. However, it may be useful for the first time a very large filesystem that compresses very little is backed up.

compress [client|server] "string"

Default: client fast. If Amanda does compression of the backup images, it can do so either on the backup client host before it crosses the network or on the tape server host as it goes from the network into the holding disk or to tape. Which place to do compression (if at all) depends on how well the dump image usually compresses, the speed and load on the client or server, network capacity, holding disk capacity, availability of tape hardware compression, etc.

For either type of compression, Amanda also allows the selection of two styles of compression. Best is the best compression available, often at the expense of CPU overhead. Fast is often not as good a compression as best, but usually less CPU overhead.

So the compress options line may be one of:

compress none
compress [client] fast
compress [client] best
compress server fast
compress server best

Note that some tape devices do compression and this option has nothing to do with whether that is used. If hardware compression is used (usually via a particular tape device name or mt option), Amanda (software) compression should be disabled.

dumpcycle int

Default: 10 days. The number of days in the backup cycle. Each disk using this set of options will get a full backup at least this often. Setting this to zero tries to do a full backup each run.

exclude [list] "string"

Default: none. The string is passed as a file name value to the GNU tar --exclude or --exclude-from option. In the case of exclude list, the file must be available on the backup client host.

If the file name is relative, the disk name being backed up is prepended. So if this is entered:

    exclude list ".amanda.excludes"

the actual file passed to GNU tar would be /var/.amanda.excludes for a backup of /var, /usr/local/.amanda.excludes for a backup of /usr/local, and so on.

holdingdisk "boolean"

Default: yes. Whether a holding disk should be used for these backups or whether they should go directly to tape. If the holding disk is a portion of another file system that Amanda is backing up, that file system should refer to a dumptype with holdingdisk set to no to avoid backing up the holding disk into itself.

ignore "boolean"

Default: no. Whether disks associated with this backup type should be backed up or not. This option is useful when the disklist file is shared among several configurations, some of which should not back up all the listed file systems.

index "boolean"

Default: no. Whether an index (catalogue) of the backup should be generated and saved in indexdir. These catalogues are used by the amrecover utility.

kencrypt "boolean"

Default: no. Whether the backup image should be encrypted by Kerberos as it is sent across the network from the backup client host to the tape server host.

maxdumps "int"

Default: 1. The maximum number of backups from a single host that Amanda will attempt to run in parallel. See also the main section inparallel option.

priority "string"

Default: medium. When there is no tape to write to, Amanda will do incremental backups in priority order to the holding disk. The priority may be high(2), medium(1), low(0) or a number of your choice.

program "string"

Default: DUMP. The type of backup to perform. Valid values are DUMP for the native operating system backup program, and GNUTAR to use GNU tar or to do Samba PC backups.

record "boolean"

Default: yes. Whether to ask the backup program to update its database (e.g. /etc/dumpdates) of time stamps. This is normally enabled for daily backups and turned off for periodic archival runs.

skip-full "boolean"

Default: no. If true and planner has scheduled a full backup, these disks will be skipped, and full backups should be run off-line on these days. It was reported that Amanda only schedules level 1 incrementals in this configuration; this is probably a bug.

skip-incr "boolean"

Default: no. If true and planner has scheduled an incremental backup, these disks will be skipped.

starttime "int"

Default: none. Backups will not start until after this time of day. The value should be hh*100+mm, e.g. 6:30PM (18:30) would be entered as 1830.

strategy "string"

Default: standard. Strategy to use when planning what level of backup to run next. Values are:

standard

The standard Amanda schedule.

nofull

Never do full backups, only level 1 incrementals.

noinc

Never do incremental backups, only full dumps.

skip

Never do backups (useful when sharing the disklist file).

incronly

Only do incremental dumps. `amadmin force' should be used to tell Amanda that a full dump has been performed off-line, so that it resets to level 1. It is similar to skip-full, but with incronly full dumps may be scheduled manually. Unfortunately, it appears that Amanda will perform full backups with this configuration, which is probably a bug.

The following dumptype entries are predefined by Amanda:

define dumptype no-compress {
    compress none
}
define dumptype compress-fast {
    compress client fast
}
define dumptype compress-best {
    compress client best
}
define dumptype srvcompress {
    compress server fast
}
define dumptype bsd-auth {
    auth bsd
}
define dumptype krb4-auth {
    auth krb4
}
define dumptype no-record {
    record no
}
define dumptype no-hold {
    holdingdisk no
}
define dumptype no-full {
    skip-full yes
}

In addition to options in a dumptype section, one or more other dumptype names may be entered, which make this dumptype inherit options from other previously defined dumptypes. For instance, two sections might be the same except for the record option:

define dumptype normal {
    comment "Normal backup, no compression, do indexing"
    no-compress
    index yes
    maxdumps 2
}
define dumptype testing {
    comment "Test backup, no compression, do indexing, no recording"
    normal
    record no
}

Amanda provides a dumptype named global in the sample amanda.conf file that all dumptypes should reference. This provides an easy place to make changes that will affect every dumptype.  

TAPETYPE SECTION

define tapetype name {
    tapetype-option tapetype-value
    ...
}

Name is the name of this type of tape medium/device. It is referenced from the tapetype option in the main part of the config file.

The tapetype options and values are:

comment "string"

Default: none. A comment string describing this set of tape information.

filemark "int"

Default: 1000 bytes. How large a file mark (tape mark) is, measured in bytes. If the size is only known in some linear measurement (e.g. inches), convert it to bytes using the device density.

length "int"

Default: 2000 kbytes. How much data will fit on a tape.

Note that this value is only used by Amanda to schedule which backups will be run. Once the backups start, Amanda will continue to write to a tape until it gets an error, regardless of what value is entered for length.

speed "int"

Default: 200. How fast the drive will accept data, in bytes per second. This parameter is not currently used by Amanda.

lbl-templ "string"

A PostScript template file used by amreport to generate labels. Several sample files are provided with the Amanda sources in the example directory. See the amreport(8) man page for more information.

In addition to options, another tapetype name may be entered, which makes this tapetype inherit options from another tapetype. For instance, the only difference between a DLT4000 tape drive using Compact-III tapes and one using Compact-IV tapes is the length of the tape. So they could be entered as:

define tapetype DLT4000-III {
    comment "DLT4000 tape drives with Compact-III tapes"
    length 12500 mbytes         # 10 Gig tapes with some compression
    filemark 2000 kbytes
    speed 1536 kps
}
define tapetype DLT4000-IV {
    comment "DLT4000 tape drives with Compact-IV tapes"
    DLT4000-III
    length 25000 mbytes         # 20 Gig tapes with some compression
}

INTERFACE SECTION

define interface name {
    interface-option interface-value
    ...
}

Name is the name of this type of network interface. It is referenced from the disklist file.

Note that these sections define network interface characteristics, not the actual interface that will be used. Nor do they impose limits on the bandwidth that will actually be taken up by Amanda. Amanda computes the estimated bandwidth each file system backup will take based on the estimated size and time, then compares that plus any other running backups with the limit as another of the criteria when deciding whether to start the backup. Once a backup starts, Amanda will use as much of the network as it can leaving throttling up to the operating system and network hardware.

The interface options and values are:

comment "string"

Default: none. A comment string describing this set of network information.

use "int"

Default: 300 Kbps. The speed of the interface in Kbytes per second.

In addition to options, another interface name may be entered, which makes this interface inherit options from another interface. At the moment, this is of little use.  

DISKLIST FILE

hostname diskdevice dumptype [ spindle [ interface ] ]

Lines starting with # are ignored, as are blank lines. The fields have the following meanings:

hostname

The name of the host to be backed up. If diskdevice refers to a PC share, this is the host Amanda will run the Samba smbclient program on to back up the share.

diskdevice

The name of the disk device to be backed up. It may be a full device name, a device name without the /dev/ prefix, e.g. sd0a, or a mount point such as /usr.

It may also refer to a PC share by starting the name with two (forward) slashes, e.g. //some-pc/home. In this case, the program option in the associated dumptype must be entered as GNUTAR. It is the combination of the double slash disk name and program GNUTAR in the dumptype that triggers the use of Samba.

dumptype

Refers to a dumptype defined in the amanda.conf file. Dumptypes specify backup related parameters, such as whether to compress the backups, whether to record backup results in /etc/dumpdates, the disk's relative priority, etc.

spindle

Default: -1. A number used to balance backup load on a host. Amanda will not run multiple backups at the same time on the same spindle, unless the spindle number is -1, which means there is no spindle restriction.

interface

Default: local. The name of a network interface definition in the amanda.conf file, used to balance network load.

Instead of naming a dumptype, it is possible to define one in-line, enclosing dumptype options within curly braces, one per line, just like a dumptype definition in amanda.conf. Since pre-existing dumptypes are valid option names, this syntax may be used to customize dumptypes for particular disks.

A line break must follow the left curly bracket.

For instance, if a dumptype named normal is used for most disks, but use of the holding disk needs to be disabled for the file system that holds it, this would work instead of defining a new dumptype:

hostname diskdevice {
  normal
  holdingdisk no
} [ spindle [ interface ] ]

TAPE MANAGEMENT

YYYYMMDD label flags

Where YYYYMMDD is the date the tape was written, label is a label for the tape as written by amlabel and flags tell Amanda whether the tape may be reused, etc (see the reuse options of amadmin).

Amdump and amflush will refuse to write to an unlabeled tape, or to a labeled tape that is considered active. There must be more tapes in active rotation (see the tapecycle option) than there are runs in the backup cycle (see the dumpcycle option) to prevent overwriting a backup image that would be needed to do a full recovery.  

AUTHORIZATION

On the client side, the amandad daemon validates the connection using one of several methods, depending on how it was compiled and on options it is passed:

.rhosts

Even though Amanda does not use rsh, it can use .rhosts-style authentication and a .rhostsfile.

.amandahosts

This is essentially the same as .rhosts authentication except a different file, with the same format, is used. The is the default mechanism built into Amanda.

Kerberos

Amanda may use the Kerberos authentication system. Further information is in the docs/KERBEROS file that comes with an Amanda distribution.

For Samba access, Amanda needs a file on the Samba server (which may or may not also be the tape server) named /etc/amandapass with share names, (clear text) passwords and (optional) domain names, in that order, one per line, whitespace separated. By default, the user used to connect to the PC is the same for all PC's and is compiled into Amanda. It may be changed on a host by host basis by listing it first in the password field followed by a percent sign and then the password. For instance:

  //some-pc/home        normalpw
  //another-pc/disk     otheruser%otherpw

With clear text passwords, this file should obviously be tightly protected. It only needs to be readable by the Amanda user on the Samba server.

Further information is in the docs/SAMBA file that comes with an Amanda distribution.
