@ -149,11 +149,14 @@ With backup fleecing, such old data is cached in a fleecing image rather than
sent directly to the backup target. This can help guest IO performance and even
prevent hangs in certain scenarios, at the cost of requiring more storage space.
Use e.g. `vzdump 123 --fleecing enabled=1,storage=local-lvm` to enable backup
fleecing, with fleecing images created on the storage `local-lvm`. As always,
you can set the option for specific backup jobs, or as a node-wide fallback via
the xref:vzdump_configuration[configuration options]. In the UI, fleecing can be
configured in the 'Advanced' tab when editing a backup job.
To manually start a backup of VM `123` with fleecing images created on the
storage `local-lvm`, run
vzdump 123 --fleecing enabled=1,storage=local-lvm

The fleecing storage should be a fast local storage, with thin provisioning and
discard support. Examples are LVM-thin, RBD, ZFS with `sparse 1` in the storage
