rsync - Apr 2011 - best option to synchronize dm-crypt archive

Hi folks :-)

I've an archive done by dm-crypt (using losetup and crysetup luksOpen I
mount this archive to os and share it by samba).

Everyday I synchronize this archive to other backup server.

Which is the best option to do a backup of this archive?

thanks

Pol

I cannot disconnect cryptsetup and losetup.. which problem can I have if I
use rsync --archive --inplace with this archive mounted?

I have a raid6 with ext3 fs
