zfs-rollback — roll ZFS dataset back to 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.

Example8: 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:
             #zfsrollback-rpool/home/anne@yesterday
