Scheduling Snapshots (BUI)
Use the following procedure to configure automatic snapshots of a filesystem, LUN, or project
and set a retention policy for those snapshots.
Automatic snapshots can be taken half-hourly, hourly, daily, weekly, or monthly and are named
.auto[-<snaplabel>]-<timestamp>. In the Creation column of the Snapshots list, times are
displayed in the local (client browser) time zone. However, times are stored and executed
in UTC format, without regard to such conventions as daylight saving time. For example, a
snapshot scheduled for 10:00 a.m. PST (UTC-8) is stored and executed at 18:00 UTC, and this
is the time that will appear as the timestamp in the snapshot name.
Automatic snapshots can be set on a project or a share, but not both. Otherwise, overlapping
schedules and retention policies would make it impossible to guarantee both schedules.
Removing an interval, or changing its retention policy, will immediately destroy any automatic
snapshots not covered by the new schedule. Automatic snapshots with clones are ignored.
Note - Previous versions of the software allowed for automatic snapshots at the frequency of a
minute. To help users avoid placing undue stress on the system, this feature was removed with
the 2010.Q3 release. If the software is rolled back, existing minutes will be preserved. Previous
instances will expire according to the existing schedule, but no new snapshots will be taken. An
alert will be posted if a share or project with this frequency is found.
