… and the VM (and its snapshot) managed to get corrupted …

Talking about rt. Our support site. Thankfully most of the stuff is in the database with a little customization. Thankfully we want to move from 3.x to 4.x. Annoyingly, this is more work.
Thankfully, our web server design is now far more intelligent than in the past. We may simply run it on the web frontend directly, rather than running it as a VM. There’s really little advantage to the VM, and we keep having to do a reset of the VM. Separate machine, lower end. Could use it for something else.
So onto RT4 we go, with a possible boot up of rt3 just to capture all the bits we are missing.
And yes, our backup is going MUCH better now.
