zfs-rollback —
roll ZFS dataset back to snapshot
| zfs |
rollback
[-Rfr]
snapshot
|
When a dataset is rolled back, all data that has changed since the snapshot is
discarded, and the dataset reverts to the state at the time of the snapshot.
By default, the command refuses to roll back to a snapshot other than the most
recent one. In order to do so, all intermediate snapshots and bookmarks must
be destroyed by specifying the
-r option.
The
-rR options do not recursively destroy the
child snapshots of a recursive snapshot. Only direct snapshots of the
specified filesystem are destroyed by either of these options. To completely
roll back a recursive snapshot, you must roll back the individual child
snapshots.
- -R
- Destroy any more recent snapshots and bookmarks, as well as
any clones of those snapshots.
- -f
- Used with the -R option to
force an unmount of any clone file systems that are to be destroyed.
- -r
- Destroy any snapshots and bookmarks more recent than the
one specified.
