bionic (1) bup-on.1.gz

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
              ...
