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.
run your backup process every few minutes, if both machines are online, it sends the latest snapshot, if not then it exits. You could reduce your snapshots to once a day, so it only does the data transfer once per day, and any extra backups just succeed.
The downside of this approach is you will need to setup alerting if a snapshot doesn’t get backed up within a window, rather then alerting on a single backup process failing. (i.e. if the server doesn’t have a successful backup within a week create an alert)
You could also do the same thing with rclone vfs mounts with full caching, so you could write locally even when the network is offline, and when you get online it would transfer (but you need to setup your server side alerting again)
