It's hard to guess what were the reasons for that, your engineer has more information about your setup and what had actually happened, as well as the logs, so I'd ask him/her about that. If you feel the case is not treated properly, you can provide your feedback using the 'Talk to a Manager' option available on the customer portal.

Can someone get back to me about the 90 days disappearing, no replies to that as yet? I have had little response to questions through the case and it`s been over a month since it was initially opened so i hope you can see my frustration with communications and length of time with this.
In Update 3 we start identifying clustered VMs a bit differently (a fix to another issue). So, if you have a cluster added to backup console via SCVMM, clustered VMs (not local ones) residing on cluster nodes will get new IDs and will be treated as new ones. This will lead to new full backups and duplicated replica entities.

You had a deleted VM retention period configured. In your case the specified value was lower than selected retention period. As the result, clustered VMs with obsolete IDs that from backup server perspective were no longer processed were wiped out from backup files.

Thanks.

That`s fine BUT not knowing this change had been made, the engineer didn`t know either so escalated it and it took almost 2 weeks to get a `lab session` organised to then tell me that this change was made in U3. We could of avoided the 90 days being removed if that information was at hand earlier (4 weeks) and i would have removed the retention option enabling our now second repo of historical backups to catch up to the 90 days we lost and as such ensure we had resilience.

I think that`s a fair point, things could have been handled better...

Agreed. But before the case got escalated to R&D, the issue (caused by one of the fixes introduced by Update 3) was unknown for us. So, the time it took us to find the root cause is explainable.

Anyway, I just wanted to share the detailed description with you as well as warn you that having deleted VM retention period lower than generic retention period is not recommended practice that might lead to multiple issues. Use it cautiously.

Thanks.
