I'm currently backuping my 300 Vms on a physical Veeam Server with local storage (SAS).
Once a week, some backup copy jobs pick up the last restore point of each backup and put them on another local volume, still on my Veeam Server.
Those local copy jobs produce a set of VBK/VIB files according my GFS policy.
I'd like to automatically push my VBK files (not the VIB) on another storage system, that is a Quantum DXi deduplication NAS. Just to have an off-site backup copy of my GFS archives.
I've tried to do some others backup copy jobs with my Quantum as destination, but merge operations are incompatible with those kind of system.
So my idea was to execute a script at the end of each local backup copy job to launch a robocopy of the VBK on my Quantum. This script runs well but my problem is that VBK files at source (produced by my backup copy job) are compressed (mandatory for my local volume). And so, deduplication is not as effective as it could be on my Quantum system.
So my question : is there any way to uncompress a VBK file and produce a "big" VBK in command line (powershell or something else...) ?
Thanks in advance for your help.
