Hello,
I have an offsite class configure to back up our network with a schedule 
for Sunday night. On monday when I ran:
bpimagelist -hoursago 24 -class offsite | grep CIB | sort -u | awk '{print $9}'

I saw four tapes in the four tapes listed.  Now yesterday when I went to 
duplicate Sunday nights backups to be sent offsite I see that Netbackup 
only used three tapes. So I am wondering how this is possible does 
bpduplicate use some form of compression?
