Honestly, I doubt Veeam see it as a priority. There have been request for this feature dating back to January 2015 - veeam-agent-for-windows-f33/feature-request-backup-validation-t25320.html
. As a software dev I find it hard to believe that an in-memory "pretend" restore that at least checks the validity of the backup files is so difficult to implement that it takes all this time to code if it was something Veeam saw as important.
I cannot rely on a backup system that cannot be either validated or even tested (without installing a spare internal drive for the purpose). Veeam Agent has great potential, but as a proper backup solution it is does not meet this basic requirement of backup software - If you cannot validate a backup then just how many copies of a backup do you judge to be necessary? Two? Five? Twenty? Without validation you are playing with probability and statistics - every one of those could be faulty; there is no way to know otherwise. Veeam seem to be enterprise-focused, for which they do provide validation functionality. That is absolutely fine as a business model. But they have decided to also target single-user PCs and they do not seem to appreciate what is required for a reliant single PC backup solution. A single workstation PC nowadays can host data that is just as valuable/more valuable as the total data held on the PCs of an entire office, or on a server. For this sole reason, the lack of ability to validate a backup, I've now switched to alternative software that can.
