tape

I backup my data every day on tape using one drive DAT HP Storageworks DAT 160. I use one tape for every day and I turn them weekly. Every monday I check one tape randomly recover some files saved on it.

I know that when data is saved on tape, the driver and backup software check data integrity, but I wonder if a manual check of some data saved has a sense or not. I re-use these tapes many times and I would be sure data are safe.
