I have a proxmox+Debian+docker server and I’m looking to setup my backups so that they get backed up (DUH) on my Linux PC whenever it comes online on the local network.
I’m not sure if what’s best is backing up locally and having something else handling the copying, how to have those backup run only if they haven’t run in a while regardless of the availability of the PC, if it’s best to have the PC run the logic or to keep the control over it on the server.
Mostly I don’t want to waste space on my server because it’s limited…
I don’t know the what and I don’t know the how, currently, any input is appreciated.
Since space is a major concern, maybe have a look at borg and possibly something like borgmatic on top for easier configuration. Borg does deduplicated backups, so you could do even hourly ones if you wanted without too much extra space depending on how many you want to keep. You’d need to run a borg server wherever you want to store your backups so it’s not a simple rsync over ssh situation but that’s the price you pay for the extra niceties.
