[Borgbackup] Backup to current QNAP NAS?

[Thomas Waldmann]

I don't use a QNAP neither do I develop/package for QNAP, so only some 
replies:

> a QNAP NAS (TS-451D2, Intel Celeron, 4GB RAM)

4GB is sufficient to run borg on it, but it depends on the amount of 
data you have in a repo, see formula in our docs.

> 1. Should I install borg on the QNAP QTS system?

If possible and you do not have too much data (so the RAM would not 
suffice): yes

Running client/server borg is often more efficient than just running the 
borg client and having the repo on a network filesystem.

Not the latest, but recent enough.

Maybe motivate the packager to package more often. :-)

Debian (and Ubuntu) packages are well-maintained, so that would be a 
good way.

But please note that once accepted into stable, the borg version won't 
be changed and will only receive rather few, rather critical fixes.

So, if you want to have something recent for borg on debian, use the 
backports repo, for ubuntu use the maintainer's ppa. There, you will 
usually find the latest borg stable release.

> 4. Some completely different solution, e.g. borg talking to QNAP Hybrid
> Backup Sync?

No idea about that. Our usual recommendation for redundancy is to make 
backups to multiple, separate repositories.
