@badnetmask My proxmox backup strategy (FWIW)
I have two prune strategies.
1 of them is to keep for a month but have 1 monthly 4 weekly 7 daily and 24 hourly
1 is to just keep the last backup
then I have three backup jobs
* Daily sends to ‘keep last' (this is more for OMG did I just screw that up?”
* every 2 hours (machines that change all the time, databases, etc..)
* every 6 hours (machines that change throughout the day, but I don't need the granularity.
