Automatic consolidation creates a new archive with the data from the original ones and deletes the older incremental or differential backups

This article applies to:

  • Acronis True Image Home 2009


Automatic consolidation in Acronis True Image Home can be set up for any backup task that creates incremental or differential backups (slices) regardless of the archive's storage place (except for removable media).

After the backup creation process is finished, the program checks for quota violations. If the quota violation is detected, Acronis True Image Home performs the automatic consolidation according to the following scenario:

  1. Identifies the oldest slice in the chain;
  2. Detects the next relative slice created after the oldest one;
  3. Creates a new archive that will contain the data stored in the original ones. If both of the detected slices contain the data with the same sector IDs, the data from the newer slice will be placed to the new archive;
  4. Associates the new archive with the rest of the chain;
  5. Deletes the older slices after the consolidation is complete.

The cycle is repeated several times until no quota violation is detected.

More information

If the new slice is put to a different place than the previous ones, the consolidated archive will be saved to the same location as the new slice.

The quota violation is only checked after the backup is created.
