Mark,
 
This is still a limitation in version 4.5.  The workaround is to
multistream.  BTW, for a 1TB backup I would always multistream, simply as a
way of finishing the backup within a reasonable amount of time.  For
example, a tape device that is able to stream data at 10MB/second would take
approximately 28 hours to backup 1TB.  Send that same backup to 4 tape
drives and you can be done in approximately 7 hours.

I'm getting this in my error logs: 
02/09/2003 22:43:32 snoopy snoopy  from client snoopy: ERR - Backup exceeds
1 terabytes 
                    in size. 
02/09/2003 22:43:47 snoopy snoopy  suspending further backup attempts for
client snoopy, 
                    policy UNIX_stg, schedule full because it has exceeded
the 
                    configured number of tries 
02/09/2003 22:43:47 snoopy snoopy  backup of client snoopy exited with
status 130 (system 
                    error occurred) 
I found this note for v3.4 that descibes problems backing up over a Terabyte
of data and suggests multistreaming from the filesystem to correct.

Can anybody comment if this is still a problem?  This is v4.5 MP2 on Solaris
8.
