Backup file naming

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.
