|

#######################
|
||
|
||
## Groups are here to share the same backup options between multiple domains.
|
||
## That way, it is possible, for example, to have a different policy retention
|
||
## for a pool of guests in testing than for the one in production.
|
||
|
||
## Define default options for all groups. ##
|
||
default:
|
||
hourly: 0
|
||
daily: 2
|
||
weekly: 2
|
||
monthly: 1
|
||
yearly: 0

## Packager to use for each backup:
|
||
## directory: images will be copied as they are, in a directory per domain
|
||
## tar: images will be packaged in a tar file
|
||
## zstd: images will be compressed with zstd. Requires python "zstandard" package to be installed.
|

packager: directory

## Options for the choosen packager:
|
||
#tar:
|
||
## # Compression algorithm to use. Default to None.
|
||
# compression: "xz"
|
||
#None | "xz" | "gz" | "bz2"
|
||
## # Compression level to use for each backup.
|
||
## # Generally this should be an integer between 1~9 (depends on the
|
||
## # compression algorithm), where 1 will be the fastest while having
|
||
## # the lowest compression ratio, and 9 gives the best compression ratio
|
||
## # but takes the longest time to compress.

## Retention policy: the first backup of the day is considered as the

## detail how many backups of each type has to be kept. Set to "*" or None for an
|
||
## infinite retention.
|
||
## Default to 5 for everything, meaning that calling "virt-backup clean" will let 5
|
||
## backups for each period not specified in the config.

## Enable the Libvirt Quiesce option when taking the external snapshots.
|
||
##
|
||
## From Libvirt documentation: libvirt will try to freeze and unfreeze the guest
|
||
## virtual machine’s mounted file system(s), using the guest agent. However, if the
|
||
## guest virtual machine does not have a guest agent, snapshot creation will fail.
|
||
##
|
||
## However, virt-backup has a fallback mechanism if the snapshot happens to fail
|
||
## with Quiesce enabled, and retries without it.
|
||
quiesce: False

||
## Hosts definition ##
|
||
hosts:
|
||
## This policy will match the domain "domainname" in libvirt, and will
|
||
## backup the disks "vba" and "vdb" only.
|
||
#- host: domainname
|
||
# disks:
|
||
# - vda
|
||
# - vdb
|
||
## Quiesce option can also be overriden per host definition.
|
||
# quiesce: False
|
||
## Will backup all disks of "domainname2" ##
|
||
#- domainname2
|
||
## Regex that will match for all domains starting with "prod". The regex
|
||
## syntax is the same as the python one
|
||
- host: "r:.*"
|
||
# disks:
|
||
# - vda
|
||
|
||
## Exclude the domain domainname3 (useful with regex, for example)
|
||
#- "!domainname3"
|
||
## Exclude all domains starting with "test"
