#### Backup groups ####
#######################

## 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

## Groups definition ##
groups:
  ## Group name ##
  mother:
    ## Backup directory ##
    target: /var/backups/vm/mother

    ## 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.
    #  compression_lvl: 5
    ##
    ## zstd:
    ##   # Compression level to use for each backup.
    ##   # 1 will be the fastest while having the lowest compression ratio,
    ##   # and 22 gives the best compression ratio but takes the longest time
    ##   # to compress.
    ##   compression_lvl: [1-22]
    #packager_opts:
    #  compression: xz
    #  compression_lvl: 6

    ## When doing `virt-backup backup` without specifying any group, only
    ## groups with the autostart option enabled will be backup.
    autostart: True

    ## Retention policy: the first backup of the day is considered as the
    ## "daily" backup, first of the week "weekly", etc. The following options
    ## 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.
    hourly: 0
    daily: 2
    weekly: 2
    monthly: 1
    yearly: 0

    ## 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"
      - "!r:^generic.*"
