Solution

Backup is not completing because the total size of backup is more than the size of a single tape. Hence there is need for deleting any unwanted data from /u01 and /var directories of th EMS.

For /var and /u01 cleanup:
1. check for any files that are older than 15 days in the log directories.
Here is an example to check in one such directory:

find /u01/app/netboss/local/STP/ -mtime +15 -exec ls -al {} \;

2. Make sure that all files older than 15 days should be deleted and there is no script file or other important file.
3. Delete the files using following command:

find /u01/app/netboss/local/STP/ -mtime +15 -exec rm -rf {} \;

NOTE: Take extreme care while running rm command because data once deleted cannot be recovered
