Open-E JovianDSS Retention Plans

Consistent snapshots for your backup strategy

Retention plans are an included feature of Open-E JovianDSS that control the automatic activation and deletion of snapshots.

They consist of rules which are defined by an interval and a retention period. The interval sets how often a snapshot should be taken and the retention period how long each snapshot should be kept. Each value is described with one of the standard time units: seconds, minutes, hours, days, weeks, months or years.

Any number of rules can be set for a retention plan to adapt it to any backup strategy.

Retention Plan example

Short term rule

Interval = 5 minutes

Retention period = 1 hour

Medium term rule

Interval = 1 hour

Retention period = 3 days

Long term rule

Interval = 1 day

Retention period = 1 month

Now the data is secured with a short-, medium- and long-term rule. Any mistakes are easily undone, and the data is secured from data corruption and viruses because it can be restored to any state from the last hour, day or month.

This animation shows 4 time axes. One for the retention plan and one for each rule that defines it, as in the example above. The moving lines are snapshots which are created and deleted based on each rule's interval and retention period.
