Multiple backups may be kept.

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. :)

There’s no point doing anything fancy like that - wireguard over Tailscale is pretty pointless, as Tailscale is literally wireguard with NAT traversal and authentication bolted on. Unless you enable subnetting, it can’t get more secure than that.

And even if you do enable subnetting (which you might wanna do if you need access to absolutely everything), you can use Tailscale ACLs to keep tighter control - say, from specific (tagged) devices.

Won’t take that long before the enshittification is complete.
