12.5 & Storagenode: Format always Version 11, even if selected Version 12

Hi all,

I built an 12.5 13400 ad-integrated environment from scratch.

There are few things with deduplication and backup format, that make me wonder, if they are bugs or intended.

  1. Default Backup options: Backup format Version 12 selected,
    all Backups are in Backup format: Version 11
  2. Location uses 11.7 deduplication - is this the current format for 12.5 13400?
    settings DEDUPLICATION_TYPE_11_7
    version LOCATION_VERSION_ABR11_7

Kind regards

Hello SEGBE,

This is the intended behavior. The format 11 is automatically set if you back up to a manged location with enabled deduplication. If you change the format to Version 12, the backups will fail: https://www.acronis.com/support/documentation/AcronisBackup_12.5/#38763.html

To my knowledge, Format 12 has built-in deduplication, it is not possible to use it together with the old deduplication algorithm of 11.7.

Hi Ekatarina,

thank you for your quick reply.

Does it mean the following: If a managed location with deduplication shall be used, there is only Version 11 format?

Kind regards

Yep, currently this is the only option if you want to use a managed location with dedup.
