       zfs-auto-snapshot - take regular ZFS snapshots


       zfs-auto-snapshot [options] [-l label] <'//' | name [name...]>


       zfs-auto-snapshot  automatically creates, rotates, and destroys snapshots for all your ZFS
       datasets, and is compatible with both zfsonlinux and zfs-fuse.


              By default zfs-auto-snapshot will snapshot all datasets except for those  in  which
              the  user-property com.sun:auto-snapshot is set to false.  This option reverses the
              behavior and requires com.sun:auto-snapshot to be set to true.

       -d, --debug
              Print debugging messages.

       -e, --event=EVENT
              Set the com.sun:auto-snapshot-desc property to EVENT.

       --fast Use a faster zfs list invocation.

       -n, --dry-run
              Print actions without actually doing anything.

       -s, --skip-scrub
              Do not snapshot filesystems in scrubbing pools.

       -h, --help
              Print the usage message.

       -k, --keep=NUM
              Keep NUM recent snapshots and destroy older snapshots.

       -l, --label=LAB
              LAB is usually 'hourly', 'daily', or 'monthly'.

       -p, --prefix=PRE
              PRE is 'zfs-auto-snap' by default.

       -q, --quiet
              Suppress warnings and notices at the console.

              Send zfs full backup. Unimplemented.

              Send zfs incremental backup. Unimplemented.

              Use CHAR to separate date stamps in snapshot names.

       -g, --syslog
              Write messages into the system log.

       -r, --recursive
              Snapshot named filesystem and all descendants.

       -v, --verbose
              Print info messages.

              Command to run before each dataset is snapshotted.  It is passed  the  dataset  and
              snapshot name. If it returns non-zero, snapshotting this dataset is aborted.

              Command  to  run  after  each dataset is snapshotted.  It is passed the dataset and
              snapshot name.

              Do not create new snapshots, but do destroy older snapshots. Has no  effect  unless
              used with -k.

              A  non-obvious use may be constructon of cron jobs or scripts that run pre-snapshot
              command(s), then  run  zfs-auto-snapshot  (without  -k)  to  quickly  snapshot  all
              datasets,  then  run  post-snapshot  command(s) and clean up with zfs-auto-snapshot

       name   Filesystem and volume names, or '//' for all ZFS datasets.
