ZFS-ROLLBACK(8) FreeBSD System Manager's Manual ZFS-ROLLBACK(8)
NAME
zfs-rollback - roll ZFS dataset back to snapshot
SYNOPSIS
zfs rollback [-Rfr] snapshot
DESCRIPTION
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.
EXAMPLES
Example 8: Rolling Back a ZFS File System
The following command reverts the contents of pool/home/anne to the
snapshot named yesterday, deleting all intermediate snapshots:
# zfs rollback -r pool/home/anne@yesterday
