[SOLVED] Tweaks for PBS datastore on slow link

[mlazzarotto]

Hi guys, I recently installed PBS on my PVE as LXC container and I'm slowly migrating all of my QEMU VMs to LXC containers.
My setup is pretty basic: my mini-pc contains both PVE and PBS, and I configured PBS to use my NAS as a datastore. The NAS is connected to PVE via a PowerLine which is kind of slow: 50Mbps at peak (because it's in the basement of the apartment building, 2 floors below).

Is there any tweak that I can implement to have faster backups over this slow link?

not really, no. your link is likely not only slow, but also not really low latency..

Hey @fabian , thanks. I was asking because I remember that on PVE I can set a `tmpdir` in the `jobs.cfg` to specify a temp direcory where (I suppose) files are elaborated before sending the backup to the NAS

 

[fabian]

that only affects certain files or backup modes, and doesn't work for PBS at all. if you need something similar for PBS, the only option is to have a PBS with local storage but aggressive pruning (e.g., only keep 1-2 backups), and syncing that to the offsite PBS that keeps the backups long term.

But in that way I'd need 2 separate PBS servers, 1 on PVE and 1 in the basement next to the NAS. Right?

 

[fabian]

no, one PBS with two datastores (one backed by the local disk, one backed by the network share one) would also work

Makes sense, I'll try that. Thank you
