bup-ls(1) [debian man page]

bup-ls(1)						      General Commands Manual							 bup-ls(1)

NAME
bup-ls - list the contents of a bup repository SYNOPSIS
bup ls [-s] [-a] DESCRIPTION
bup ls lists files and directories in your bup repository using the same directory hierarchy as they would have with bup-fuse(1). The top level directory contains the branch (corresponding to the -n option in bup save), the next level is the date of the backup, and subsequent levels correspond to files in the backup. When bup ls is asked to output on a tty, it formats its output in columns so that it can list as much as possible in as few lines as possi- ble. However, when bup ls is asked to output to something other than a tty (say you pipe the output to another command, or you redirect it to a file), it will output one file name per line. This makes the listing easier to parse with external tools. Note that bup ls doesn't show hidden files by default and one needs to use the -a option to show them. Files are hidden when their name begins with a dot. For example, on the topmost level, the special directories named .commit and .tag are hidden directories. Once you have identified the file you want using bup ls, you can view its contents using bup join or git show. OPTIONS
-s, --hash show hash for each file/directory. -a, --all show hidden files. EXAMPLE
bup ls /myserver/latest/etc/profile bup ls -a / SEE ALSO

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 ... 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 autho- rized 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
