| | 1 | WHAT IS RSYNC? |
| | 2 | -------------- |
| | 3 | |
| | 4 | rsync is a replacement for rcp that has many more features. |
| | 5 | |
| | 6 | rsync uses the "rsync algorithm" which provides a very fast method for |
| | 7 | bringing remote files into sync. It does this by sending just the |
| | 8 | differences in the files across the link, without requiring that both |
| | 9 | sets of files are present at one of the ends of the link beforehand. |
| | 10 | At first glance this may seem impossible because the calculation of |
| | 11 | diffs between two files normally requires local access to both |
| | 12 | files. |
| | 13 | |
| | 14 | A technical report describing the rsync algorithm is included with |
| | 15 | this package. |
| | 16 | |

| | 18 | USAGE |
| | 19 | ----- |
| | 20 | |
| | 21 | Basically you use rsync just like rcp, but rsync has many additional options. |
| | 22 | |
| | 23 | Here is a brief description of available options: |
| | 24 | |
| | 25 | Options: |
| | 26 | -v, --verbose increase verbosity |
| | 27 | -c, --checksum always checksum |
| | 28 | -a, --archive archive mode (same as -rlptDog) |
| | 29 | -r, --recursive recurse into directories |
| | 30 | -R, --relative use relative path names |
| | 31 | -b, --backup make backups (default ~ extension) |
| | 32 | -u, --update update only (don't overwrite newer files) |
| | 33 | -l, --links preserve soft links |
| | 34 | -L, --copy-links treat soft links like regular files |
| | 35 | -H, --hard-links preserve hard links |
| | 36 | -p, --perms preserve permissions |
| | 37 | -o, --owner preserve owner (root only) |
| | 38 | -g, --group preserve group |
| | 39 | -D, --devices preserve devices (root only) |
| | 40 | -t, --times preserve times |
| | 41 | -S, --sparse handle sparse files efficiently |
| | 42 | -n, --dry-run show what would have been transferred |
| | 43 | -W, --whole-file copy whole files, no incremental checks |
| | 44 | -x, --one-file-system don't cross filesystem boundaries |
| | 45 | -B, --block-size SIZE checksum blocking size |
| | 46 | -e, --rsh COMMAND specify rsh replacement |
| | 47 | --rsync-path PATH specify path to rsync on the remote machine |
| | 48 | -C, --cvs-exclude auto ignore files in the same way CVS does |
| | 49 | --delete delete files that don't exist on the sending side |
| | 50 | --force force deletion of directories even if not empty |
| | 51 | --numeric-ids don't map uid/gid values by user/group name |
| | 52 | --timeout TIME set IO timeout in seconds |
| | 53 | -I, --ignore-times don't exclude files that match length and time |
| | 54 | -T --temp-dir DIR create temporary files in directory DIR |
| | 55 | -z, --compress compress file data |
| | 56 | --exclude FILE exclude file FILE |
| | 57 | --exclude-from FILE exclude files listed in FILE |
| | 58 | --suffix SUFFIX override backup suffix |
| | 59 | --version print version number |
| | 60 | |
| | 61 | |
| | 62 | SETUP |
| | 63 | ----- |
| | 64 | |
| | 65 | Rsync uses rsh or ssh for communication. It does not need to be setuid |
| | 66 | and requires no special privilages for installation. It does not |
| | 67 | require a inetd entry or a daemon. You must, however, have a working |
| | 68 | rsh or ssh system. Using ssh is recommended for its security |
| | 69 | features. |
| | 70 | |
| | 71 | To install rsync, first run the "configure" script. This will create a |
| | 72 | Makefile and config.h appropriate for your system. Then type |
| | 73 | "make". |
| | 74 | |
| | 75 | Once built put a copy of rsync in your search path on the local and |
| | 76 | remote systems (or use "make install"). That's it! |
| | 77 | |
| | 78 | |
| | 79 | MAILING LIST |
| | 80 | ------------ |
| | 81 | |
| | 82 | There is a mailing list for the discussion of rsync and its |
| | 83 | applications. It is open to anyone to join. I will announce new |
| | 84 | versions on this list. |
| | 85 | |
| | 86 | To join the mailing list send mail to listproc@samba.anu.edu.au with |
| | 87 | no subject and a body of "subscribe rsync Your Name". |
| | 88 | |
| | 89 | To send mail to everyone on the list send it to rsync@samba.anu.edu.au |
| | 90 | |
| | 91 | |
| | 92 | BUG REPORTS |
| | 93 | ----------- |
| | 94 | |
| | 95 | If you have web access then please look at |
| | 96 | http://samba.anu.edu.au/rsync/ |
| | 97 | |
| | 98 | This will give you access to the bug tracking system used by the |
| | 99 | developers of rsync and will allow you to look at other bug reports or |
| | 100 | submit a new bug report. |
| | 101 | |
| | 102 | If you don't have web access then mail bug reports to |
| | 103 | rsync-bugs@samba.anu.edu.au or (if you think it will be of interest to |
| | 104 | lots of people) send it to rsync@samba.anu.edu.au |
| | 105 | |
| | 106 | |
| | 107 | CVS TREE |
| | 108 | -------- |
| | 109 | |
| | 110 | If you want to get the very latest version of rsync direct from the |
| | 111 | source code repository then you can use anonymous cvs. You will need a |
| | 112 | recent version of cvs then use the following commands: |
| | 113 | |
| | 114 | cvs -d :pserver:cvs@samba.anu.edu.au:/cvsroot login |
| | 115 | Password: cvs |
| | 116 | |
| | 117 | cvs -d :pserver:cvs@samba.anu.edu.au:/cvsroot co rsync |
| | 118 | |
| | 119 | Look at the cvs documentation for more details. |
