AMVAULT(8) System Administration Commands AMVAULT(8)
NAME
amvault - Copy Amanda dumps from one volume to another
SYNOPSIS
amvault [-o configoption...] [--dry-run | -n] [--quiet | -q] [--fulls-only] [--exact-match] [--export] [--src-timestamp src-timestamp]
--label-template label-template --dst-changer dst-changer [--autolabel autolabel-arg...]
config [hostname [ disk [ date [ level [ hostname [...] ] ] ] ]]
WARNING
This application is not yet in its final form, and is subject to major revision in subsequent versions of Amanda. Backward compatibility is
not guaranteed.
Note that Amanda restore/recover operations will request tertiary media by label when dumpfiles are not found on secondary media, but there
is no provision to automatically fetch such media from a different changer
Feedback on and patches to this application are invited and encouraged!
DESCRIPTION
Amvault is conceptually equivalent to "amfetchdump | taper". That is, it reads specified dumps from secondary media and re-writes them on
tertiary media.
Amvault Copies data from the run with timestamp src-timestamp onto volumes using the changer dst-changer, and labeling new volumes with
label-template.
Secondary Media
The dumps to be read from secondary media can be specified by any combination of dump specifications, --fulls-only, and --src-timestamp. At
least one must be specified, lest amvault attempt to vault all dumps in the catalog. See amanda-match(7) for more information on dump
specifications.
Note that the datestamp given in the dumpspec is the dump datestamp - the run in which the backup was taken on the Amanda client. The
--src-timestamp, on the other hand, is the write timestamp - the run in which the dump was written to secondary media. The latter option
facilitates duplicating the results of an entire backup run, including any dumps that might have been flushed from holding disk.
Tertiary Media
The --dst-changer must be specified, and names the changer in which tertiary media are stored.
If amanda.conf(5) contains the new part-size splitting parameters, then amvault will use them without any additional configuration.
However, if the configuration still uses the old splitting parameters (tape_splitsize, split_diskbuffer, and fallback_splitsize), then
amvault will need some additional configuration in order to properly split dumps to tertiary media. To do so, specify a new tapetype in
amanda.conf(5), say "TERTIARY", and set the part-size and other appropriate parameters there. Then reference that tapetype in the amvault
invocation:
amvault -otapetype=TERTIARY ...
OPTIONS
--autolabel [any] [other-config] [non-amanda] [volume-error] [empty]
Works just like the autolabel parameter in amanda.conf(5), and can be specified multiple times if necessary. The default is 'empty'.
--dst-changer dst-changer
Specifies the changer in which tertiary media are stored. In general, this should be different from the secondary changer, to eliminate
the possibility of overwriting secondary media with tertiary data.
The dst-changer parameter should specify the name of a changer defined in amanda.conf(5). For example:
define changer vaulting_tape {
tapedev "/dev/rmt/1n"
tpchanger "chg-zd-mtx"
changerdev "/dev/sg0"
changerfile "vaulting-changer.conf"
}
--dry-run, -n
Cause amvault to print the dumps it would vault, but not actually perform any vaulting operations.
--exact-match
The host and disk are parsed as exact values
--export
Cause amvault to attempt to move completed tertiary volumes to import/export slots, where they can be more easily removed by an
operator.
---fulls-only
Only full (level-0) dumps are copied.
--label-template label-template
Specifies a label template which is used to generate new labels for tertiary volumes.
--quiet, -q
Eliminate non-error messages, and is useful when running amvault from cron.
--src-timestamps src-timestamps
Specifies the timestamps in the format 'YYYYMMDDHHMMSS' of the run to vault, can be "latest", then the most recent amdump or amflush
run will be used.
-o configoption
See the "CONFIGURATION OVERRIDE" section in amanda(8).
EXAMPLES
Vault all dump written to tape in the latest amdump or amflush run:
$ amvault --src-timestamps latest --label-template "CONF-%%%" --dst-changer vault-changer CONF
Vault all dump written on the run of December 7 2011 12:13:14 :
$ amvault --src-timestamps 20111207121314 --label-template "CONF-%%%" --dst-changer vault-changer CONF
Vault all dump dumped on any run of December 7 2011:
$ amvault --label-template "CONF-%%%" --dst-changer vault-changer CONF * * 20111207
