However, if he is talking about 'tarring' the pc tree component for a BackupPC incremental backup, then the deletions are indeed encoded in the attrib files, though I am not sure how he would intend to reconstruct it all in practice without some code to glue it back together properly unless he is already has a copy of the fulls and is maintaining a full incremental chain... That being said, if that is what he means, he could just literally tar the incremental backup tree... however, he would still lose the pooling benefits... ------------------------------------------------------------------------------ Symantec Endpoint Protection 12 positioned as A LEADER in The Forrester Wave(TM): Endpoint Security, Q1 2013 and "remains a good choice" in the endpoint security space.
