Amen to prying LTO out of my cold dead hands. Yes they are pricey at the SMB level, and getting Backup Exec to play nice is always a fun game, but the cartridges are cheep enough to keep full backups permanently every week/month for both DR and Compliance.
That, and I've never had trouble getting a customer that has previously lost data to budget for one to do them properly.
At that scale, Robotic tape libraries may become an out of hand cost but geeze, some kind of offline backup people! Imagine if they'd Cryptolocker'd their on network - did this scenario never occur to them?
