If you back up your data to tape, do you also
verify the data on the tape after
According to Kroll Ontrack, an
leader in data recovery,
Of all of the media that is used for data backups, tape is the poorest and least
60% of all tape backups are defective.
- Tape stretches over
time, distorting the tape and making it difficult to impossible to read.
- Tape is subject to
changes in temperature and humidity, again, distorting the tape.
- The read/write head and
rollers make physical contact with the tape. Over time, the magnetic media on
the tape can be worn away.
- The exposed tape on a
tape cartridge can collect dust. Dust particles then can get in between the
read/write head and the tape, causing a read/write error to occur
- Tapes are not stored
properly between uses.
- Tapes are used over and
over and over and…until they are no longer viable. But, because they’re not
checked, no one knows this.
So, the only way to know
if your tape backup is any good is to verify the files on it – every single time
you do a tape backup. Just because the last backup was OK doesn’t mean that the
next one will be.
What should you do?
You should still continue
to do to backups in whatever format and on whatever media you are currently
using. But, then,
augment those backups with
