Backups created in Acronis True Image (2020 or 2021) and Acronis Cyber Protect Home Office

Acronis True Image 2020 introduced a new backup format - TIBX, which is even more reliable and convenient. The TIBX format is used for disk backups created to internal drives, external drives, network storage.

To learn more about backup file naming, see Backup file naming.

Backup schemes

Backing up in the TIBX format supports all backup schemes. As opposed to the TIB format, which saves every backup version as a separate file, the TIBX format saves full and differential backup versions as separate files, while incremental backup versions are automatically merged into their base backups (full or differential).

Cleaning up TIBX format backups

If you’d like to clean up backup versions you do not need anymore, use automatic and manual cleanup methods.

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.

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, refer to Backup file naming.
