You can also back up your compose file and data directories, pull the backup from another computer, and as long as the architecture is compatible you can just restore it with no problem. So basically, your services are a whole lot more portable. I recently did this when dedipath went under. Pulled my latest backup to a new server at virmach, and I was up and running as soon as the DNS propagated.
Initramfs listening with dropbear to prompt me for my passphrase. I can ssh in if I needed to reboot, or if it’s lost power for longer than my ups can keep it running.
