Backups are great. Restores are better!

Storage backup

The Alaskan Department of Revenue has just learned the hard way that your backups are only as good as your restores.

A report by AP that was picked up Woonsocket Call, a local paper in Rhode Island, says the department wiped out a disk drive containing information on an account worth $38 billion. But worse still, when it turned to the backup tapes to recover the data, it was unreadable.

P.S: Not every backup issue can be avoided but there are resources to help. Here’s one if you have time: a free seminar that’s coming to a city near you this year.

    Good story - proves the need to test restores on a regular basis.

    vendor scare tactic? is there a list of total industry examples?

    Hi Frank, We appreciate your skepticism. But in this instance a list of industry examples in which tapes have not been readable for restore purposes would probably wrap around the planet.

    I wish I could say with 100% certainty that every backup I wrote to tape was readable. However, that's the reason you don't keep "one" backup tape. You take weekly, monthly and quarterly backups for this very reason - to increase the chances of getting data sets from multiple pieces of media. Archival backups are only good if they can be tested for readability, then perfectly preserved. Without both, the archival backup is a shot in the dark.
