NAME

amvault - Copy Amanda dumps from one volume to another

CONTENTS

SYNOPSIS

amvault [-o configoption...] [--dry-run | -n] [--quiet | -q] [--fulls-only] [--latest-fulls] [--incrs-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, --incrs-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.

--incrs-only

Only incremental (level > 0) dumps are copied.

--label-template label-template

Specifies a label template which is used to generate new labels for tertiary volumes.

--latest-fulls

The latest full of every DLE in the disklist that do not have the skip strategy.

--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
