To specify advanced settings for the backup job:

1.At the Storage step of the wizard, click Advanced.
2.Click the Advanced tab.
3.Select the Enable automatic backup integrity checks check box if you want Veeam Backup & Replication to verify integrity of storage metadata in backup files (VBK, VIB and VRB). Storage metadata describes how data blocks in the backup file map to backed up VM files, contains deduplication data index and some other auxiliary information.

Storage metadata can get damaged for different reasons, for example, physical storage corruption or a communication issue with the storage device during backup. If storage metadata is corrupted, Veeam Backup & Replication will be unable to determine which data blocks belong to backed up VM files, and you will not be able to restore VM data from the backup file.

The integrity check is performed at the beginning of the backup job session. During the integrity check, Veeam Backup & Replication verifies storage metadata in all backup files that will be affected during the backup process. If the check fails, Veeam Backup & Replication displays a notification message and prompts you to create a new active full backup. During such active full backup, no integrity check is performed.

Note that the integrity check verifies only storage metadata in the backup file. To perform a CRC check for all data blocks in the backup file, you can create a SureBackup recovery verification job and enable the Validate entire virtual disk contents option in the job.  To learn more, see Performing Recovery Verification.

4.In the VM retention section, specify the number of days to keep backup data for deleted VMs. If a VM is no longer available (for example, it was deleted or moved to another location), Veeam Backup & Replication will keep its data in the backup repository for the period you specify in the Remove deleted VMs data from backup after field. When this period is over, data of the deleted VM will be removed from the backup repository. The retention period for deleted VMs is particularly useful if the job is configured to create synthetic full backups with subsequent transform and you want to make sure that the full backup does not include redundant data. To learn more, see Retention Policy for Deleted VMs.
5.If you want to execute custom scripts before and/or after the backup job, select the Run the following script before the job and Run the following script after the job check boxes and click Browse to choose executable file(s).

You can select to execute pre- and post-backup actions after a number of backup sessions or on specific week days.

If you select the Run every... backup session option, specify the number of the backup job sessions after which the script(s) must be executed.
If you select the Run on selected days only option, click Days and specify week days on which the script(s) must be executed.



Custom scripts you define in the advanced job settings relate to the backup job itself, not the VM quiescence process. To specify pre-freeze and post-thaw scripts for VM image quiescence, use the Guest Processing step of the wizard.
