You could set up syncthing to a pc at home and pull backups from there

Do you have unlimited data transfer with your vps? Transferring 40Gb three times each and every day is quite some traffic.

Why not host it at home then? I bought a used lenovo thinkcenter (m720q on top of my head) for 75€ It uses only 35 watt, it has 750 Gb storage and I only added some RAM.

I pay 1€ per month for a fixed public ip to avoid ddns. My NAS is at a family member (over vpn to home) for offsite backups.

To compress you need diskspace. Simple as that. Three daily from 40 Gb in small files? By thor, sure hope you think incrementals. Have you tried backupc?

But honestly, it’s worth -and most reliable- to invest in a new bigger disk to solve the problem instead of working your way around it.

Linux : 4Gb.

In that case, select a few that looks interesting to you. Read & compare tests but above all user reviews. (Positive, review … well yeah, you expect it to work. I usually find the low reviews more telling than the positives. What one sees as negative might not be relevant for me or may be critical.)

I have something similar to a small cabin, build with unifi in mesh mode. Works just fine, but i only need connectivity, not much more but one video stream is possible.

Depends very much on the repeater and on what you gonna do in the office. Stay away from one-radio repeaters. You get better bandwith and stability with :

A) an outdoor ap in wifi client mode. You run a cable from that to a switch in the office and cables from there to pc, printers etc. That’s how I connected a remote ip camera. Works flawless.

B) multi radio repeater (one radio talks to the router, the other radio is an ap on another chanel)

C) two one-radio ap’s with utp between them and the same as above under B
