The thread title is probably a misnomer at this point because most of the discussions for the last month or two has been around people that were still having various issues even after moving to 64K. I'm sure at least some of the issues are the same, but the problem with 4K is that it needs a lot more memory to survive.
Well good/bad news then. I'm actually still running 4K. I've been put in a situation where I don't have enough disks to migrate my data off, and at the same time, have too much data to just say eff it and start over! So I'm stuck!
The good news is I'm actually completely free of crashes or lockups and have been running for a couple months now without issue. But there are two caveats:
1. I cannot run synthetic full backups in my backup jobs. This causes the backup VM to lock up via RAM usage.
2. I cannot run Backup copy jobs that are over 2TB+. They have synthetic full component that I can't disable. This causes the backup copy VM to lock out via CPU usage.
I'm running the experimental refs.sys on my backup copy vm. However it doesn't appear to have any effect. I'm happy to pull any logs for Veeam or Microsoft
