Client side deduplication for Mac OS X

Hi,

I am using Mac OS X 10.6 for a file server and we are considering a backup solution for it.

Does anyone know whether NetBackup 7.5 support a client side deduplication option for Apple Mac OS X?

If it support, anyone know what would be possible deduplication ratio for normal design related files?

Any information about Mac OS X client option would be highly appreciated.

Thanks a lot.

Regards,

Rich
