Applies To: Windows Server 2012 Essentials
This topic applies to a server running Windows Server 2012 Essentials or Windows Server 2012 R2 Essentials, or to a server running Windows Server 2012 R2 Standard or Windows Server 2012 R2 Datacenter with the Windows Server Essentials Experience role installed.
Daily backups of all your computers accumulate on your server over time. To help you manage these backups, Windows Server Essentials can help you manage the database of computer backups. You can configure how many backups to keep for all your computers.
The Backup Retention Policy determines how long a backup is kept before it is deleted during the backup cleanup process. Backup cleanup runs at 11:59 PM every Saturday. It deletes all the backups that fall outside the Backup Retention Policy. The defaults for the Backup Retention Policy are:
Retain daily backups for 5 days. The first backup of the day is retained as the daily backup. After 5 days, the oldest daily backup is deleted in the cleanup process.
Retain weekly backup for 4 weeks. The first backup of the week is retained as the weekly backup. After 4 weeks, the oldest weekly backup is deleted in the cleanup process.
Retain monthly backups for 6 months. The first backup of the month is retained as the monthly backup. After 6 months, the oldest monthly backup is deleted in the cleanup process
Open the Dashboard.
In the Devices Tasks pane, click Customize Computer Backup and File History settings.
Note In Windows Server 2012 R2 Essentials, this task is renamed to Client Computer backup tasks.
In Client computer backup settings and tools, in the Client computer backup retention policy section, make the changes to the retention policy that meets your needs.
When you finish, click OK to apply the changes and close the dialog box. The updated retention policy will be applied the next time that backup cleanup runs.
Note The updated retention policy applies to all of the client computers on your network that are configured for backup.
