You're lucky your environment is as large as it is. In my experience, the larger the environment, the better the success rate.
Large environments tend to have more tape drives, more robots, and more budget. Hence you lose one out of 50 tape drives, you're still likely to have better than 99% success. In an environment with 10 drives, you lose one drive, you could lose 5-10%, depending on how thin your overhead is. I've supported Netbackup environments with 100 to 2500 backup jobs. 10 failures daily, out of 2500 wasn't uncommon. That's only about 1/2 of a percent. You could lose an entire media server and still have over 95% success on a given night. In an environment with 100 clients, 2-4 failures is not uncommon......that's a much bigger hit. Lose a media server early in your backup window an you could have 0% success on a given night. Not to mention, the smaller environments usually have less strict change control, which means clients are being patched, upgraded, have untested software installed, have different NIC drivers, etc, etc. That being said, I'm personally very uncomfortable with backup success rates < 98%.
