As our EMC Centera increases in usage, our backups have been taking
longer and longer. We do a full backup on Friday nights and
differentials during the week. The full backup is now taking over 20
hours during the weekend. Since the CBRM module only creates one saveset
stream the options are limited for tuning on the Legato side. The stream
is unable to keep a single LTO-2 drive busy, so upgrading to LT0-4/VTL
or save_to_disk doesn't appear to be a viable option. 

EMC's has suggested to either: 1) Only do full backups yearly 2) Buy a
second Centera, create an offsite and do replication to it. Since we
find both suggestions laughable, and EMC has no 3rd option, does anyone
using CBRM have any suggestions?
