Overview

Achieving a low-maintenance backup schedule with comfortable job retention periods is a measure of your backup policy’s success. Appropriate Job Retention and Recycling settings can ease the administrative burden of providing enough space for future backups to complete, while ensuring a known period of backups remain available for timely restores.

Many factors contribute to the optimal recycling settings, including:

  • Overall size of backup jobs

  • Frequency of backup jobs scheduled

  • Total size of the CFA (RAID) space

  • Whether replication is being used (everyone using byte-level replication need to use a schedule and retention policy that ensures you have sufficient time for a second full backup to completely replicate over to the secondary before purging the oldest or the original full backup. It is recommended to have a minimum of two full backups on the CFA at a given time, preferred is three.)

  • Exclusion settings (matchers) to make sure you are not backing up more information than is needed.

Please set up you recycling settings keeping the above factors in mind, monitor, and change as needed until you achieve your optimal settings.

Preserve Single Job Set

Preserve Single Job Set setting tells the CFA not to recycle a job until a viable replacement exists. It is recommended to use to ensure that the most recent full backup and any subsequent differential and/or incremental backups stay on the CFA and are not deleted automatically.

How to set the CFA to be notified of low disk space problems?

  1. Log in to the CFA Management Console, and go to System.

  2. In the Monitoring group, click Email, configure email settings, and then click Apply.

  3. In the Monitoring group, click System Alerts.

  4. In the System Alerts group, select Disk Storage Utilization, and then click Submit.

  5. In the Monitoring group, click Disk Thresholds.

  6. In the Percentage of disk space remaining before sending warnings, specify the desired disk space in gigabytes, and then click Submit.

  7. On the upper right, click Activate Configuration.

How to temporarily disable retention settings?

To temporarily disable retention settings, log in to the CFA Management Console, go to Jobs > Settings, and clear Enable Automatic Job Management. This will disable all retention settings globally.

This is useful if:

  • you want to keep a job on the RAID a little bit longer than the retention settings allow, or

  • you are importing a backup job from an archive drive, and the job will be older than the current retention settings.

    If you don’t disable retention, the job will import from the archive drive and will be immediately deleted as an expired backup.
