Retention policy

Retention policy for incremental backups

Organizations typically have a policy of retaining backup information to help the organization recover business-critical data in the event of a site-wide data loss. These policies, however, often require the disposal of backup information that is no longer needed. Manually tracking down and deleting data that has exceeded the backup retention period is a hassle that no one wants to deal with.

To ease backup management, RecoveryManager Plus has backup retention. The feature allows you to define a backup retention period, which is the number of days that the product will store incremental backup information. When the specified number of days is up, the incremental backup is assimilated into the full backup.

How it works

If you want to enable backup retention, the product prompts you to set a retention period during the domain backup settings configuration. Multiple incremental backups can happen in the same day, either scheduled or manual, but only the number of days that have incremental backups are used to determine the backups that will be retained.

When you configure the product for the first time, it backs up all objects present.

At any time, the oldest available backup will be the full backup.

Whenever an incremental backup is completed, the number of days that have incremental backups is checked. If the number of incremental backups is less than the retention period, the product continues its normal operation.

Assuming you set a backup retention period of seven days, on the eighth day, the number of days that have incremental backups exceeds the value set in the retention policy.

So, the incremental backups made on the first day after the last full backup are assimilated into the full backup.

This way, the total number of incremental backups stored is kept at the desired level.

Another scenario that may affect the retention feature is when the product already has X days’ worth of incremental backups and the retention period set is less than X.

As shown above, the number of incremental backups is greater than the value set in the retention policy. In such a case, the incremental backups made during the last seven days are retained and all previous incremental backups are added to the full backup.
