bup-on(1) General Commands Manual bup-on(1) NAME bup-on - run a bup server locally and client remotely SYNOPSIS bup on <hostname> index ... bup on <hostname> save ... bup on <hostname> split ... bup on <hostname> get ... 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 sub- command 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 exam- ple, 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 re- mote hosting provider, you could back them up to a local (much less ex- pensive) 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 ...
