Scheduled Snapshots Using the BUI

In addition to manual snapshots, you can configure automatic snapshots according to the table below. These snapshots are named ".auto-<timestamp>", and can be taken on half hourly, hourly, daily, weekly, or monthly schedules. A schedule is a list of intervals and retention policies.

Times are displayed in the local (client browser) time zone. However, times are stored and executed in UTC format and 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.

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.

Previous versions of the software allowed for automatic snapshots at the frequency of a minute. This proved to put undue strain on the system and was not generally useful. To help users avoid placing undue stress on the system, this feature was removed with the 2010.Q3 release. Snapshots can now only be specified at a period of once every half hour or longer. Existing minute periods will be preserved should the software be rolled back, and 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.
