This has been fixed

This article applies to:

  • Acronis Backup & Recovery 10 Advanced Server
  • Acronis Backup & Recovery 10 Advanced Server - Small Business Server Edition
  • Acronis Backup & Recovery 10 Advanced Workstation
  • Acronis Backup & Recovery 10 Advanced Server - Virtual Edition

Symptoms

  1. You create a backup policy with Grandfather-Father-Son (GFS) backup scheme that saves backups to Centralized Managed Vault;
  2. After some time you notice that while the backups are deleted from the vault view according to GFS clean-up scheme, the space is not freed up on the vault location.

Cause

This is a known issue.

Solution

The backups will be deleted when the retention period for the first full backup is over.

This has been fixed and the fix is available in the latest released build. See Installation of the latest update of an Acronis product.

(!) The fix will only work for backups created with the latest build of the product. If you have backups created with Acronis Backup & Recovery 10 Build 11639 or lower, the issue will persist.

More information

For example you have the following chain of backups created by the GFS scheme:

F1+I1+I2+D1+I3+I4+I5+I6+D2+I7+I8+I9+I10+F2...

...where F1-F2 are full backups, I1-I10 are incremental backups, D1-D2 are differential backups.

The clean up task will not delete the incrementals between F1 and D1, D1 and D2, D2 and F2 when the time comes. These archives will be deleted along with the whole chain between F1 and F2 only when the retention period for all backups until F2 is over.

This is true only for backups stored on Centralized Managed Vault, i.e. when the clean-up is performed by Acronis Storage Node itself. However if the backups are saved to unmanaged vaults, then there will be no such issue since the clean-up is performed by on the Agents side locally on behalf of Acronis Managed Machine service which can properly delete the incrementals between F1 and D1, D1 and D2, D2 and F2 when the time comes according to the GFS scheme.
