In case automatic or manual cleanups are configured, some small auxiliary files may stay in the
storage after the cleanup. Windows may show the size of these files bigger than the real one. You
can see the physical size by checking Windows file properties.
Please do not delete any files manually!
Cleaning up local backups manually has the following scheme:
Full backups can be deleted with the dependent versions only.
Differential backup versions can be deleted independently of any other backup versions.
Incremental backups:
If it is the last backup chain, then any incremental backup can be deleted to free up the
space.
If it is not the last backup chain, any incremental backup version can be deleted only
together with all other incremental versions of the same chain.
Which backups retain TIB format
The following backups continue to use the TIB format:
File-level backups
Nonstop backups
Notarized backups
Backups which use CD/DVD/Blu-ray, FTP, or Acronis Secure Zone as their destination
To compare naming of a .tibx archive with a .tib archive in detail, please refer to Backup file naming
(p. 41).
Refer to Cleaning up backups, backup versions, and replicas (p. 82) for more details about automatic
cleanup.
For more details about manual cleanup, refer to Cleaning up backup versions manually.
