+#### 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 ##

+    ## 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.

+    ## 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.

+    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.*"
