Add rclone backend

[aawsome]

Idea: Start a backgroud rclone serve restic --addr localhost:0 and read the correct address from the output. Then simply use the REST backend to access it.

How do we use the rclone mechanism?

I did something like this (I'm writing from memory as I'm away from my computer, so the syntax might not be quite the same)
rustic-rs --repository rclone:path init
rustic-rs --repository rclone:path backup /root/foldername

And it created the repo just fine, and created various snapshots.

But it seems to have put the repo in /root/rustic, not in my remote storage. Rclone is connected just fine and can be used by restic or mounted/synced by itself.

The syntax is identical to restic: rclone:remote:path.
E.g. I use a rclone remote ovh and use rustic-rs -r rclone:ovh:backup /dir/to/backup.

Could it be you didn't specify a rclone remote?

If it still doesn't work, please specify which command you exactly used, thanks!

Oh, I think I see my error. I used rclone:remote/path rather than rclone:remote:path. It's interesting that it didn't throw an error, and instead created the repo in /root/path (the rustic binary is in /root. Perhaps some sort of syntax check would be useful when the repo path begins with rclone:?

rclone also accepts local paths. So if you don't specify a remote, rclone just accesses local dirs.
I'll think about whether to add an warning.
