TIB file naming (Acronis Support please verify)

Could some (from Acronis, or someone else who knows this stuff) please verify my assertions/assumptions in this message?

I would like to have a comprehensive description of the automatic TIB file naming conducted by ATI 11 backups. The product documentation lacks this level of detail - my assumptions here are based on tests.

TEST

Source Data: C:/data - folder with 60G of data
TIB/Backup location: \\fileserver\backup\Daily.tib
Options: Split archive into 15G chunks
Backup type: differential​

The first time the backup runs, the following are created (file is split due to option to split into 15G chunks):

- Daily1.tib - 15G
- Daily2.tib - 15G
- Daily3.tib - 13G​

The next time the backup runs, Daily4.tib is created (roughly 400M). Succeeding executions of the backup creates Daily5, Daily6, ... Dailyn.

If in C:/data there is more than 15G of modified data (since the first execution of the differential backup which acted like a full backup), the next execution of the backup will create multiple Dailyn.tib files, due to the splitting.

Assertions/Assumptions:

1. All executions of a differential backup to the same location (same TIB file) will produce new TIB files with a numeric suffix added to the base name (<file>). If an execution of the backup requires multiple files due to archive splitting, than n files will be created: <file>k+1 ... <file>k+n.
2. Data recovery is conducted by using the base file, or the first one in the sequence. A sequence of differential backups allows a checkpoint of the data each time the backup was run.
3. Restarting the sequence requires the files to be renamed/removed before the backup runs as each successive execution of a differential backup to the same TIB file will create new files in the same series.

Thank you,

Kevin.

 

Hello Kevin,

Thank you for choosing Acronis Disk Backup software

We'd like to inform you that automatic backup naming works exactly the the way you described it in this post. Your suggestions about the differental backups are also correct.

Concerning creating new set of differentials, the differential backups require only the full one to be usable. In this case, to distinguish certain backup, we recommend you to put archive comments to each backup so you could easily find the necessary data to restore instead of renaiming them.

The instructions on how to provide comments for archives are shown in section 5.2.8 of Acronis True Image User Guide.

If you have any further questions concerning our software, please submit a request for technical support or post any of them on this forum. We will do our best to help you as soon as possible.

Thank you
