Haha i get that. I feel like proxmox backup server is really great together with proxmox though. And idk but I feel like there is not too much to do wrong? Correct me if you think differently, but we use a mirrored hdd zfs pool on pbs and pve, so we have 4 copies plus snapshots ob the backup server. So harddrive failure is not really a problem. And deleting or corrupting files or databases manually on accident can happen, but they can be revived sometimes or restored from last nights backup And yes, the backup server could die, but the drives should be fine still. And yes, it can burn down but then you have a mirrored drive on the home lab. I think its rather difficult to delete stuff on the bps on accident. I would just not delete anything manually. If its too full, either increase the pruning job for old snapshots or just put in a mother pair of drives.

Maybe I am cheap but its also fun I think. Also I feel like my data is actually mine now?
