Do a backup of a remote directory to a local repository
If we want to backup a remote directory to a local repository, how might we make that work?
Suppose we have permission to log into a remote machine, but the remote machine does not have permission to login to our server, we should be able to perform 'put' of a remote directory.
This doesn't necessarily have to be a builtin command, but perhaps a script or tutorial that does the correct ssh invocations.
User feedback:
To expand on the need for this: it’d be useful for people who wish to back up from (e.g.) a vps to their home server, without exposing the home server to the internet. That’s my use-case anyway. It’s cheaper for me to put a big disk in my home server than it is to hire a hosted box.
We technically only need to send ephemeral keys to the client, and we can configure the serve into put only mode for the user.
$ bupstash rput --host ssh://$server $PUTARGS
export BUPSTASH_RPUT_CONNECT_COMMAND="ssh $OPTS $HOST"
Or add to bupstash a client mode analogous to the server mode so that the local machine (home pc, central backup server) would use SSH to start the client on the remote machine and connect its input and output to a local bupstash in server mode. This wouldn't require anything about SSH access to the local machine or local server configuration as the local machine could fully specify options and parameters of both the remote and local client calls.
Bupstash already speaks over stdin/stdout
Yes, I noticed as soon as I sent the comment and I actually updated it while you replied. Sorry.
Another option is to include an sftp client in bupstash so that it is able to pull files directly from a remote machine without being installed there.

Would this have any benefits over a sshfs FUSE mount besides convenience and no dependecy on sshfs?
sshfs is an unmaintained project - but I suppose it would amount to the same thing.
