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.
