+#######################
+
+## 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. ##

+  daily: 2

+    ## 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

+    #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.

+    ##
+    ## 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.
