Think twice about your last sentence. What should cause a local *copy*
to be changed??

zope might write to the Data.fs while it is copied, thus an inconsistent
copy would be backuped, even inside one filesystem.

This is not the point. rsync will run into if the file to be synced changes
in-between the sync operation. This will happen with the Data.fs - it won't
happen with a static copy. An inconsistent copy of the Data.fs is not the problem since invalid transaction entries will be discarded by the ZODB.
So rsyncing a copy of the Data.fs it the way to go.
