7 Reasons Why Data Backup is Here to Stay

Data storage backup has evolved considerably over the last two decades. Tape once prevailed with organizations running full backups either every night or each week. Tape cartridge after tape cartridge would be shipped off site for that rainy day they hoped would never come.

Then someone realized that full backups were mostly repeats of data previously backed up. So incrementals became popular – only backup new or changed data. That gave rise to the next logical extension – use deduplication to store one complete set of organizational data on disk (though many also kept additional tape copies offsite).
