usage="usage: $exname -d DEST1 [-d DEST2 [...]] [-u USER] [DIR1 [DIR2 ...]] |
|||
|
|||
Preserve as much as possible the source structure, keeping hard-links, acl, |
|||
exact numerical uids and gids, and being able to resume in very large files. |
|||
|
|||
Options: |
|||
DIR1 ... DIRn |
|||
Local directories that should be mirrored on destination(s). |
|||
|
|||
examples: /etc /home /var/backups |
|||
|
|||
If no directories are provided, the config file root |
|||
entries will be used all as destination to copy. |
|||
|
|||
-d DESTn |
|||
Can be repeated. Specifies host destination towards which |
|||
files will be send. Note that you can specify port number after |
|||
a colon and a bandwidth limit for rsync after a '/'. |
|||
|
|||
examples: -d liszt.musicalta:10022 -d 10.8.0.19/200 |
|||
|
|||
-u USER (default: 'backuppc') |
|||
|
|||
Local AND destination user to log as at both ends to transfer file. |
|||
This local user need to have a NOPASSWD ssh login towards it's |
|||
account on destination. This destination account should have |
|||
full permissions access without passwd to write with rsync-server |
|||
in the destination directory. |
|||
|
|||
-h STORE (default is taken of the hostname file) |
|||
|
|||
Set the destination store, this is the name of the directory where |
|||
the files will all directories will be copied. Beware ! if 2 hosts |
|||
use the same store, this means they'll conflictingly update the |
|||
same destination directory. Only use this if you know what you |
|||
are doing. |
