Backup file naming

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

Naming convention for backup files created by Acronis True Image 2020 or higher

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 Acronis Secure Zone as their destination

Naming convention for backup files created before Acronis True Image 2020

A backup file name has the following attributes:

• Backup name
• Backup method (full, inc, diff: full, incremental, differential)
• Number of backup chain (in the form of b#)
• Number of backup version (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.
