Hi R.walat,
First: Welcome to the forums
Second: I might misunderstand your request, but you should be able to recover from ANY backup with ANY of those few computers. When you use another PC, all you need to do is browse to the correct backup chain. then you will be able to recover from that backup. the scenario here:
https://helpcenter.veeam.com/docs/agent ... tml?ver=21 is written for original location, but if you simply browse to another backup chain (from another computer) you can recover from there also.
One of the scenario's I already used (a few times) is to install a brand new PC, fully clean instead of doing BMR from my old PC to the new hardware (depends on how much I "played" with that old PC

). But when the installation is finished, I installed VAW on it and used it to restore my previous files from my old computer
Cheers
Mike
