Still using Private Internet Access (PIA).
Honestly, dunno why they’ve fallen out of fashion due to the FUD about being owned by an unsavoury parent company, but the most important matter to me is if they keep logs, which they don’t. One of the few VPN companies tested on this, in court, and in a recent audit. Plus still extremely cheap (if you go for 3yr+3mo).
Port forwarding works with with this docker NAS stack. Doesn’t use gluetun, but there’s a specialised docker-wireguard-pia container as part of the stack, with a script that handles port changes. Been flawless.
Nice work, but if I may suggest - it lacks hardlink support, so’s quite wasteful in terms of disk space - the number of ‘tags’ (snapshots) will be extremely limited.
At least two robust solutions that use rsync+hardlinks already exist: rsnapshot.org and dirvish.org (both written in perl). There’s definitely room for backup tools that produce plain copies, instead of packed chunk data like restic and Duplicacy, and a python or even bash-based tool might be nice, so keep at it.
However, I liken backup software to encryption - extreme care must be taken when rolling and using your own. Whatever tool you use, test test test the backups. :)
