Apply the rules (only if the retention rules are set) Cleanup schedule (only if On schedule is selected)  Delete the oldest full backup  If there is only one full backup left and a full backup is in progress, then delete the last full backup This setting is recommended when backing up to a USB drive. This setting is not applicable to managed vaults. This setting enables deletion of the last backup in the archive, in case your storage device cannot accommodate more than one backup. However, you might end up with no backups if the program is not able to create the new backup for some reason. Specifies when to apply the retention rules. For example, the cleanup procedure can be set up to run after each backup, and also on schedule. This option is available only if you have set at least one retention rule in Retention rules. Specifies a schedule for archive cleanup. For example, the cleanup can be scheduled to start on the last day of each month. This option is available only if you selected On schedule in Apply the rules. Examples Weekly full backup The following scheme yields a full backup performed every Friday night. Full backup: Schedule: Weekly, every Friday, at 10:00 PM Here, all parameters except Schedule in Full backup are left empty. All backups in the archive are kept indefinitely (no archive cleanup is performed). 5.2.9 Archive validation Set up the validation task to check if the backed up data is recoverable. If the backup could not pass the validation successfully, the validation task fails and the backup plan gets the Error status. To set up validation, specify the following parameters 1. When to validate - select when to perform the validation. As the validation is a resourceintensive operation, it makes sense to schedule the validation to the managed machine's offpeak period. On the other hand, if the validation is a major part of your data protection strategy and you prefer to be immediately informed whether the backed up data is not corrupted and can be successfully recovered, think of starting the validation right after backup creation. 2. What to validate - select either to validate the entire archive or the latest backup in the archive. Validation of a file backup imitates recovery of all files from the backup to a dummy destination. Validation of a volume backup calculates a checksum for every data block saved in the backup. Validation of the archive will validate all the archive's backups and may take a long time and a lot of system resources. 3. Validation schedule (appears only if you have selected the on schedule in step 1) - set the schedule of validation. For more information see the Scheduling section.

5.2.9
Archive validation
Set up the validation task to check if the backed up data is recoverable. If the backup could not pass
the validation successfully, the validation task fails and the backup plan gets the Error status.
To set up validation, specify the following parameters
1.
When to validate
– select when to perform the validation. As the validation is a resource-
intensive operation, it makes sense to
schedule
the validation to the managed machine's off-
peak period. On the other hand, if the validation is a major part of your data protection strategy
and you prefer to be immediately informed whether the backed up data is not corrupted and can
be successfully recovered, think of starting the validation right after backup creation.
2.
What to validate
– select either to validate the entire archive or the latest backup in the archive.
Validation of a file backup imitates recovery of all files from the backup to a dummy destination.
Validation of a volume backup calculates a checksum for every data block saved in the backup.
Validation of the archive will validate all the archive’s backups and may take a long time and a lot
of system resources.
3.
Validation schedule
(appears only if you have selected the on schedule in step 1) - set the
schedule of validation. For more information see the Scheduling section.
