What determines that a restore job will be "restartable"?  I've looked in both 
the server and client manuals but all I have found are instructions for 
restarting or querying restartable restores.  The online help for the client 
had some information about options that would make a restore non-restartable, 
but we thought we had met the requirements and the restores still do not show 
up as restartable.  I queried the list for "restartable" and found some 
information, but nothing specific.  If you can point me to the information 
about this I would appreciate it.

Thanks
