I've seen the figure 25-30 years bandied about for data tape. Data backups
are a double edge sword. They have better error correction so the data is
more resilient. However, if there's an unrecoverable error it renders ALL
data for that particular file (and if it's in the directory area, all data
on the tape) unrecoverable. With digital audio tape the error only affects
that portion of the recording.
