Reclaiming Backup Repository Space
When a backup or recovery point is deleted in a Backup Repository, the space occupied by that backup or recovery point is marked as “free” and can be reused by new data blocks on the next job runs. However, the actual size of the Backup Repository may not change. The size of a Backup Repository can be reduced by rearranging the data blocks so there are no “free” ones occupying storage space. The amount of space that can be freed up is displayed in parentheses after the amount of used space. This is applicable if the repository type is Forever-incremental. Otherwise, if the repository type is Incremental with full backups, space reclaiming is not required. It is enough to delete the backups or recovery points to free up space and continue backing up to the repository.
For the incremental with full backup Backup Repository type, it is technically impossible to remove recovery points if there is no full backup after them. Make a full backup before deleting older recovery points.
Reclaiming free space can take the same amount of time as copying the entire Backup Repository to the storage where it is located (that is, if your repository size is 500 GB, reclaiming free space can take the same amount of time as copying 500GB of data to the storage where the Backup Repository is located).
Refer to the following topic to learn how to start and stop the reclaiming process:

Important
Space reclaim requires at least 500 MB of free space on the repository storage in order to start.
To reclaim free space, follow the steps below:
-
Go to the main menu of NAKIVO Backup & Replication and click Settings.
-
Go to the Repositories tab and choose a Backup Repository.
