Start new backup set

You need to force a Backup job or Backup Copy job to create a new backupset.

or

The backup files have been removed from disk, and you need to remove the file references from Veeam's configuration database.

Note: Please ensure that the destination will have the space needed to start a new backup set.

Step 1: Remove Existing Backup Set

Steps on removing backup files from configuration can be found here:
https://helpcenter.veeam.com/docs/backup/vsphere/remove_from_backups.html

Note: If the Backup Set that is being removed is for a Backup Copy job, make sure to Disable the Backup Copy job first. If this is not done, the "Remove from configuration" option will be greyed out and unavailable. 

Step 2: Run the Job

Run the job, a new backup set will be started.

Important Notes:

• The files that are removed from configuration will no longer be controlled by the job's retention policy. They will remain on disk where they were left until they are manually removed.
• There may be multiple entries under Backups>Imported for the files that were removed from backups previously then were brought back in after a rescan of the repository.
• For Backup Copy Jobs with Archival fulls enabled - Make sure to check the box to remove archived fulls when removing from configuration. Otherwise a new incremental from the most recent archived restore point will be created.
