Dear All,
Writing to tape of our old (indeed very old) files appeared to be more 
complicated than originally anticipated (see below), and we are 
considering to delete some significant fraction, in particular the files 
whose owners will not indicate their relevance for storing them on tape.
It is important to realize that work disk is in principle not backed up, 
and all critical files should be stored on tape by owners.
Please look again at the list of files in both listed below paths. In 
future we plan to implement automatic deletes after some expiration 
time, so all relevant files should be stored.
Best regards,

It looks like there are about 11 million files.  Can you tar them up 
into bundles before we move them to tape?
