2 full backups,counter set to 1

Thread needs solution

I have my counter set to 1 string but on one machine I have 2 full backups. The files are named as follows; my_partitions_full_b30_s1.tib and the second is: my_partitions_full_b30_s1-2.tib. can someone explain the 1-2 nomenclature and can I delete the first, oldest, file? Thank you, cbp

Charles, welcome to these user forums.

Please see the ATIH 2015 User Guide which states:

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.

If you do decide to delete the older of these duplicate files, please then perform a Valdiation of your backup task that created them so that the Acronis Database information is reconciled for the files which are present on your backup drive.  If you can any messages saying the Validation process cannot find a file, then take the Ignore option for each / any of these messages.
