Sorry, is there an easy way to backup a server (e.g. Debian)? Do you use the provider's "backup your instance" feature? How can you be confident that they'll never close your account and lose ypur backups, for example based on an assumption that something you're doing isn't legit?
I use http://duplicity.nongnu.org to back up my data (not the whole server). I don't know if it's necessarily the best thing these days, but it works OK.
I think the risk of losing my VPS, my working copy and my backups at the same time is acceptably low, given that the world would not end if my git repos disappeared anyway.
