bup-save(1) General Commands Manual bup-save(1) NAME bup-save - create a new bup backup set SYNOPSIS bup save [-r host:path] <-t|-c|-n name> [-#] [-f indexfile] [-v] [-q] [--smaller=maxsize] <paths...>; DESCRIPTION bup save saves the contents of the given files or paths into a new backup set and optionally names that backup set. Note that in order to refer to your backup set later (i.e. for restora- tion), you must either specify --name (the normal case), or record the tree or commit id printed by --tree or --commit. Before trying to save files using bup save, you should first update the index using bup index. The reasons for separating the two steps are described in the man page for bup-index(1). By default, metadata will be saved for every path, and the metadata for any unindexed parent directories of indexed paths will be taken di- rectly from the filesystem. However, if --strip, --strip-path, or --graft is specified, metadata will not be saved for the root directory (/). See bup-restore(1) for more information about the handling of metadata. OPTIONS -r, --remote=host:path save the backup set to the given remote server. If path is omitted, uses the default path on the remote server (you still need to include the `:'). The connection to the remote server is made with SSH. If you'd like to specify which port, user or private key to use for the SSH connection, we recommend you use the ~/.ssh/config file. -t, --tree after creating the backup set, print out the git tree id of the resulting backup. -c, --commit after creating the backup set, print out the git commit id of the resulting backup. -n, --name=name after creating the backup set, create a git branch named name so that the backup can be accessed using that name. If name al- ready exists, the new backup will be considered a descendant of the old name. (Thus, you can continually create new backup sets with the same name, and later view the history of that backup set to see how files have changed over time.) -d, --date=date specify the date of the backup, in seconds since the epoch, in- stead of the current time. -f, --indexfile=indexfile use a different index filename instead of $BUP_DIR/bupindex. -v, --verbose increase verbosity (can be used more than once). With one -v, prints every directory name as it gets backed up. With two -v, also prints every filename. -q, --quiet disable progress messages. --smaller=maxsize don't back up files >= maxsize bytes. You can use this to run frequent incremental backups of your small files, which can usu- ally be backed up quickly, and skip over large ones (like vir- tual machine images) which take longer. Then you can back up the large files less frequently. Use a suffix like k, M, or G to specify multiples of 1024, 1024*1024, 1024*1024*1024 respec- tively. --bwlimit=bytes/sec don't transmit more than bytes/sec bytes per second to the server. This is good for making your backups not suck up all your network bandwidth. Use a suffix like k, M, or G to specify multiples of 1024, 1024*1024, 1024*1024*1024 respectively. --strip strips the path that is given from all files and directories. A directory /root/chroot/etc saved with "bup save -n chroot --strip /root/chroot" would be saved as /etc. Note that cur- rently, metadata will not be saved for the root directory (/) when this option is specified. --strip-path=path-prefix strips the given path prefix path-prefix from all files and di- rectories. A directory /root/chroot/webserver/etc saved with "bup save -n webserver --strip-path=/root/chroot /root/chroot/webserver/etc" would be saved as /webserver/etc. Note that currently, metadata will not be saved for the root directory (/) when this option is specified. --graft=old_path=new_path a graft point old_path=new_path (can be used more than once). A directory /root/chroot/a/etc saved with "bup save -n chroot --graft /root/chroot/a=/chroot/a" would be saved as /ch- root/a/etc. Note that currently, metadata will not be saved for the root directory (/) when this option is specified. -#, --compress=# set the compression level to # (a value from 0-9, where 9 is the highest and 0 is no compression). The default is 1 (fast, loose compression) EXAMPLES $ bup index -ux /etc Indexing: 1981, done. $ bup save -r myserver: -n my-pc-backup --bwlimit=50k /etc Reading index: 1981, done.
