All This and Archives Too?

Today, archives and backups are two different beasts. There was a time, not too long ago, when archiving simply meant putting your tapes in a better class of long-term storage facility. But today, backups are all about data protection, while archives are about data retention and control, with emphasis on the ability to build information about--and maintain relationships between--different types of data.

In the world of backups, the only relationship data has is with its location on the storage device being backed up. None of the processes we've covered so far take it beyond that, and the only information actually being kept is file name, extension, source location, date and time--with a smattering of other data relevant only to the backup application in charge. Archiving demands that additional metadata be collected, which can then be used to establish where that data fits in the big picture of your business.

This metadata then becomes the foundation of a useful long-term archive. A number of companies have learned this the hard way, when a process server shows up at the door with a subpoena for all documents pertaining to research, development, manufacture, marketing and safety testing of that swell new product ... the one that took your company five years to develop. And that includes any e-mail, internal memos, spreadsheets, presentations, photographs, calendar appointments and sketches on cocktail napkins.
