NAME

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

SYNOPSIS

       bup on <hostname> index ...

       bup on <hostname> save ...

       bup on <hostname> split ...

DESCRIPTION

       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
       basement.

EXAMPLES

              # First index the files on the remote server

              $ bup on myserver index -vux /etc
              bup server: reading from stdin.
              Indexing: 2465, done.
              bup: merging indexes (186668/186668), done.
              bup server: done

              # Now save the files from the remote server to the
              # local $BUP_DIR

              $ bup on myserver save -n myserver-backup /etc
              bup server: reading from stdin.
              bup server: command: 'list-indexes'
              PackIdxList: using 7 indexes.
              Saving: 100.00% (241/241k, 648/648 files), done.
              bup server: received 55 objects.
              Indexing objects: 100% (55/55), done.
              bup server: command: 'quit'
              bup server: done

              # Now we can look at the resulting repo on the local
              # machine

              $ bup ftp 'cat /myserver-backup/latest/etc/passwd'
              root:x:0:0:root:/root:/bin/bash
              daemon:x:1:1:daemon:/usr/sbin:/bin/sh
              bin:x:2:2:bin:/bin:/bin/sh
              sys:x:3:3:sys:/dev:/bin/sh
              sync:x:4:65534:sync:/bin:/bin/sync
              ...
