Backup file naming

Depending on the version by which a backup was created, its name will differ.

Naming convention for backup files created in Acronis True Image (2020 or 2021) and Acronis Cyber Protect Home Office

A backup file name has only the backup name and an incremental counter. It does not contain any additional information such as backup method, backup chain number, backup version number, or volume number.

A backup name may look like:

1. my_documents.tibx
2. my_documents_0001.tibx
3. my_documents_0002.tibx
4. my_documents_0003.tibx

Full and differential backups are stored in separate files and incremental backups are automatically merged into full backups.

The following backups continue to use the TIB format and naming convention:

• File-level backups for all destinations except for Acronis Cloud. File-level backups to Acronis Cloud are in .tibx format.
• Nonstop backups
• Notarized backups
• Backups which use CD/DVD/Blu-ray, FTP, or Secure Zone as their destination

Naming convention for backup files created before Acronis True Image 2020

A TIB backup file name has the following attributes:

• Backup name
• Backup method (full, inc, diff: full, incremental, differential)
• Number of backup chain Sequence of minimum two backup versions that consist of the first full backup version and the subsequent one or more incremental or differential backup versions. Backup version chain continues till the next full backup version (if any). (in the form of b#)
• Number of backup version The result of a single backup operation. Physically, it is a file or a set of files that contains a copy of the backed up data as of a specific date and time. Backup version of files created by Acronis Cyber Protect Home Office have a .tibx extension. The TIBX files resulting from consolidation of backup versions are also called backup versions. (in the form of s#)

• Number of volume (in the form of v#)

  For example this attribute changes when you split a backup into several files. Refer to Backup splitting for details.

Thus a backup name may look the following way:

1. my_documents_full_b1_s1_v1.tib
2. my_documents_full_b2_s1_v1.tib
3. my_documents_inc_b2_s2_v1.tib
4. my_documents_inc_b2_s3_v1.tib

If you are creating a new backup, and there is already a file with the same name, the program does not delete the old file, but adds to the new file the "-number" suffix, for example, my_documents_inc_b2_s2_v1-2.tib.
