When we were running LTO3, we also were consistently able to fill up tapes for a certain data set to about 1.2 TB. We had multiple restores of all 1.2 TBs and validated the data. The data was actually cold backups of Oracle databases, which surprised us since we had the same idea that if they were ASCII text files, then yea, I could see that, but databases?

My LTO3 tapes handling more than 800GB (about 1.2TB) on the media's report. I don't have any idea for this.. The backup not running the compression also.. Is it maybe the block size or something?
