Dude you're preaching to the converted. I actually spend a good month
doing a formal document and proposal for server replacement and library
plus netbackup upgrade and various improvements over the current set up
such as deduplication etc all to be told "no we are not spending any
money and backups are not important so we will get a new library only"
I of course then found the hba we had was not compatible with solaris8
and so had to build Os on 2 other disks and swap em out.
Complete nightmare.
Cheers
