We employed tape backup as a form of sneaker-net to move large (for the day) amounts of data around the country in the early 1990s. Manufacturer's claims for MTBF notwithstanding, we discovered in a very short time that triple backups were an absolute necessity if data were to be trusted to tapes. Lost data on tape was about a 1% occurrence for us, which translated to about 2 tapes a month that had to rely on their first backup, and one tape a year that had a double failure and relied on its secondary backup.
