bup-on - run a bup server locally and client remotely


bup on <hostname> index ...

bup on <hostname> save ...

bup on <hostname> split ...


bup on runs the given bup command on the given host using ssh. It runs a bup server on
the local machine, so that commands like bup save on the remote machine can back up to the
local machine. (You don't need to provide a --remote option to bup save in order for this
to work.)

See bup-index(1), bup-save(1), and so on for details of how each subcommand works.

This 'reverse mode' operation is useful when the machine being backed up isn't supposed to
be able to ssh into the backup server. For example, your backup server can be hidden
behind a one-way firewall on a private or dynamic IP address; using an ssh key, it can be
authorized to ssh into each of your important machines. After connecting to each
destination machine, it initiates a backup, receiving the resulting data and storing in
its local repository.

For example, if you run several virtual private Linux machines on a remote hosting
provider, you could back them up to a local (much less expensive) computer in your
