Switching to Seal Mode

Veeam Backup & Replication allows you to put any of the extents of your scale-out backup repository into Seal mode.

Sealing up extents gives you the ability to gradually remove data located on these extents by applying a retention policy. You can use this feature to gracefully stop using some of your extents as backup repositories and exclude them from the scale-out backup repository configuration altogether.

When sealing up an extent, Veeam Backup & Replication restricts any further data saving to such a sealed extent and allows only read operations such as restore, merge and remove.

All backup jobs that are targeted to a scale-out backup repository with the sealed extents that store active backup chains will be forced to create a new active full backup on the next run. The new active full will be saved to another available extent in the scale-out backup repository scope, thereby forming a new active backup chain. The extent to which the new active full is going to be saved is chosen automatically by Veeam Backup & Replication, depending on the available resources.

All restore points that exceed the specified retention period will be continuously removed from the sealed extents on each subsequent backup session.

Consider the following:

  • An extent can be put into both the maintenance and seal modes at the same time.

When both modes are applied, maintenance mode overrides seal mode.

  • When putting an extent into seal mode, you will still be able to restore, merge and remove data without exiting this mode.

To put an extent into seal mode:

  1. Open the Backup Infrastructure view.
  2. In the inventory pane, select the scale-out backup repository under the Scale-out Repositories node.
  3. In the working area, select an extent and click Seal Mode on the ribbon or right-click an extent and select Seal mode.
