Which Set Is Where? — TechKnowSurge

About this interactive

You will want more than one copy, and the lesson shows how a rotation of tape sets gives you that. A set is loaded into the drive and written. Next week it is rotated out to local storage on site, where it is ready for a fast restore, and a fresh set goes into the drive. The week after, the set on site goes to an off-site safe, and the set that was in the safe comes back to be written again. So at any time one set is being written, one recent copy is on site, and one older copy is off site. With three sets, each one comes back to the drive every three weeks.

What you'll learn

Track where each tape set is in a weekly drive, on-site shelf and off-site safe rotation, which set holds a given week's backup, and which one survives a disaster at the site
