I'm setting up off-site backup, how?
My dad also used to self-host. Now I run all of the services he used to, and more.
Anyway, his server is still around so I thought I might as well use it for an offsite backup box, I run a matrix instance and nextcloud, as well as other things. But those two are the contents of which matter most.
How would you set this up?
Just a nightly rsync over sftp? That seems ineffecient. Is there a best way ro do this?
wireguard tunnel, carve off an lv on his network, expose it as an ataoe/iscsi/whatever device over wg, connect it on your end, write a luks volume to it. periodically connect, unlock, mount, rsync all your shit to it, unmount, lock, disconnect?
or just create a gpg'd backup set and rsync it over wg? or just rsync over wg if you dont give a shit about encryption or anything.
