Backup/Recovery ChallengesBackup/Recovery Challenges
Explosive data growth Increasing reliance on roaming profiles Missing backup windows Network backups spill over into primetime Hard to validate backup success Slow and error-prone restores Too many tapes (on and off-site) What if a hurricane struck Houston?

Lessons LearnedLessons Learned
New tape technologies are really fast Half the hardware delivers twice the speed Remove the tape bottleneck and other bottlenecks may arise
Tape can be used to compliment a backup to disk strategy
Media costs are not the only area of savings Maintenance Personnel
Backup improvements can easily pay for themselves Reduced risk of backup window overruns Improved ability to recover files quickly Truck-less offsite backups for disaster avoidance: Priceless.
