### btrfs support for local backup remote
Xen Orchestra may leverage btrfs features of a local filesystem remote formatted with btrfs:
* to transparently compress backup images
* to segment the backup data using subvolumes (eg. subvolume per VM or per VDI)
* to snapshot a VM's delta backup data for recovery
** instead of losing all backup data in case of error (eg. merge timeout), XO may detect a failure and revert changes at the FS level, allowing a retry of the backup in delta mode instead of triggering a full backup
