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.
