I know, but since I was planning to move, I would prefer to move also to 
the DataStore.

The BLOB store have problems with the backups because the files removed 
after the last backup are lost and it is not possible to restore 
completely the snapshot done at the moment of the backup.

I guess I will have to deserialize the DB nodes in order to get the 
reference to the DataStore. Or I can hack the Property class to get the 
RAW property with the SHA-1 from the node.
