How Do I Reduce the Vault Space Occupied by Backups?

Symptom

The size of a disk backup is much greater than the used space of the disk displayed on a server. Even if you delete large files from the disk and back up the disks again, the backup size does not reduce significantly.

Possible Cause

After files are deleted from a disk, the data remains though it is no longer available. When you use CBR to back up a disk, all disk data including the invisible data will be backed up. For the backup principles, see Why Is My Backup Size Larger Than My Disk Size?.

Solution

Currently, CBR cannot help reduce the backup size. You can use a third-party tool to do this but need to evaluate the security of the tool by yourself.
