Are you sticking with them or looking elsewhere? At work, I am not sure about recommending anything besides vSphere and Hyper-V since I haven’t used any other solution.
I have been looking at other solutions for my lab and was wondering what other professionals were turning to at work and home.
Pbs is very good at what it does. Deduplicaton is great. You can restore images or files, Easier then veeams file restore appliance imho. Live restore works great. And a user on pve can not delete the backups if you set it up right. You can easily replicate the datastore to a offsite. The backups are very fast for running vm’s with qemu’ dirty block tracking.
But…
There is no application aware in pbs itself. You need to hook into qemu-guest-agent fsfreeze if you want to prepare oracle for backups. Can find scripts on github.
And there is no DR replication that uses the dirty block tracking to do a short replication to a ready vm. I have scripted a simple restore after backup to have a dr vm ready to start but it is not compareable to veeam dr replication. This is on proxmox roadmap tho, so hopefully soon.
