Manage Disk Space

Either before or after a backup, Macrium Reflect can automatically remove old backups to free drive space for later backups using the following mechanisms:

• Delete full backups and their associated Incremental or Differentials backups older than a stated number of days or weeks.

• Keep a maximum number of full backups and their associated Incremental or Differential backups, removing excess backups just before or just after the next full backup.

Deletion rules

• The current backup set (the one you are creating or incrementing) is never purged.

• When a full backup is deleted, any linked incremental or differential backups are also deleted.

• Backup sets are purged on a per-directory basis.

• File deletions are logged in the log window.
