Just started using the append only feature to prevent a potential hacker from wiping out backups that live on a remote ssh server. Combined with restricted ssh access this can be made quite secure. I also tested writing backups to my Android phone (as a backup target) using Termux and Wireguard, worked flawlessly with a bit of tuning (keeping the vpn alive)

Append only modes are brilliant. Is there an easy way to hook into something like Glacier Deep Archive? That would be super cost effective.

I backup to a Hetzner storage box and a Raspberry Pi at home.
