Gentlemen,
 
A warning! It is important to note that when you copy tapes, 
error blocks may appear/disappear. If you are copying VMS BACKUP 
savesets, it is extremely important that you leave on the CRC 
checking and redundancy grouping capabilities of VMS BACKUP. 
Otherwise, there is a distinct chance that your saveset may get 
corrupted. 
 
While it is often painful, precautions are necessary to ensure 
that the savesets you copy (and take off of the site) are usable 
in the event of a problem!
