+ To run zfSnap periodically you can add these options to your
+ /etc/periodic.conf
+
+ xPERIODICx_zfsnap_enable - Enable xPERIODICx snapshots
+ (values: YES | NO)
+ xPERIODICx_zfsnap_fs - Space separated zfs filesystems
+ to create non-recursive snapshots
+ xPERIODICx_zfsnap_recursive_fs - Space separated zfs filesystems
+ to create recursive snapshots
+ xPERIODICx_zfsnap_ttl - Set Time To Live
+ xPERIODICx_zfsnap_verbose - Verbose output (values: YES | NO)
+ xPERIODICx_zfsnap_flags - zfSnap generic flags
+ (except -v and -d)
+ xPERIODICx_zfsnap_enable_prefix - Create snapshots with prefix
+ (Default = YES)
+ xPERIODICx_zfsnap_prefix - Set prefix to use for new snapshots
+ (Default = "xPERIODICx-")
+ (where xPERIODICx is any of hourly, daily, weekly, monthly, reboot)
+
+ xPERIODICx_zfsnap_delete_enable - Delete old snapshots periodically
+ (values: YES | NO)
+ xPERIODICx_zfsnap_delete_flags - zfSnap generic flags
+ (except -v and -d)
+ xPERIODICx_zfsnap_delete_verbose - Verbose output (values: YES | NO)
+ xPERIODICx_zfsnap_delete_prefixes - Space separated list of prefixes
+ of old zfSnap snapshots to delete
+ 'hourly-', 'daily-', 'weekly-',
+ 'monthly-' and 'reboot-' prefixes
+ are hard-coded
+ (where xPERIODICx is any of daily, weekly, monthly)
+
+
+ Add these lines to your /etc/crontab
+ 4 * * * * root periodic hourly
+ @reboot root periodic reboot
+
+ NOTE: it is not recommended to delete zfSnap snapshots every hour.
+ Deleting zfs snapshots takes more time than creating them.
+ There for it's better to delete snapshots once per day...
+
+
+ Periodic scripts provide very limited feature set. If you want to use
+ more advanced setup, you need to call zfSnap from crontab directly.
+ This way you can combine all sort of parameter combinations.

+ info.
