How can the administrator minimize the number of failures?

Refer to the exhibit.

Two media servers, sharing a library with 10 tape drives, exist in the NetBackup 8.0environment displayed in the exhibit. Both weekly full and daily differential incremental backups need to run for the clients and each schedule has a different retention period. Because of network topology, some clients back up to Media Server 1 and some back up to Media Server 2. The environment suffers from multiple status 96 failures during the backup window.
