Which Copy Do You Reach For?

About this interactive

Where you store backups is one of the biggest decisions in a backup design: on site or off site. An on-site copy is close at hand. When something goes wrong, you can restore it quickly, and it costs less to store. An off-site copy is slower to get to, but it survives what happens to the site. If a fire destroys the building and the backup with it, only the off-site copy is left. That is why most organizations keep both: the on-site copy for speed in everyday restores, the off-site copy for resilience when the site itself is lost.

What you'll learn

Choose between an on-site backup copy (faster, cheaper restore) and an off-site copy (survives a disaster at the site) for a given restore need
