Mirroring OS X folders with Rsync

[Dimitri Larmuseau]

we are using rsync version 2.5.5 protocol version 2.6 that provides 
support for hfs,  see options below :

...
-- nohfs        receive fileset from non-HFS+ filesystem
-- ufs2hfs     send non-HFS+ filest to HFS+ filesystem
...

if i'm not mistaking, it comes standard with OSX 10.2.6 or you can 
download RsyncX 1.7d for OSX, the hfs supported version is included in 
the package.
it works perfectly for us in a test environment with 40G of living data, 
(have not tested it in a production environment, will do shortly)

kind regards,
Dimitri.
