I have 24TB of data that I need to backup. We have a 1 year document retention policy. We are using Commvault with Datadomain for disk backup and Quantum 1800 and 506 for our tape (LTO3) backups.
We try to do full weekly backups. Its too hard to backup 24TB on LTO3 tapes? Whats the best practice for backups and schedule? Our goal is to save money and increase restore time.
