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 restoration), 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 directly 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 already 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, instead 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 usually be backed up quickly, and skip over
              large ones (like virtual 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 respectively.

       --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 currently, 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 directories.

              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 /chroot/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)
