The technology overlap between backup, redundancy and archiving can often lead to confusion, but each has a different role to play in streamlining and safeguarding data. Backups essentially create a second copy of data at specific points in time, ideally keeping multiple historic copies. Redundancy establishes a straight copy of an entire system, ready to take over if the original system fails. Backup offers a certain level of redundancy, and redundancy a basic level of backup, but neither are stand-alone solutions.
Archiving makes a primary copy of selected data with the aim of retaining data in the long-term. Not all of the data contained in a backup will ultimately end up in an archive so archiving is rarely an adequate backup solution in itself but as a complementary approach, it can considerably optimize the data storage process.
Most backup strategies rely on a combination of backup, redundancy and archiving. An important factor to bear in mind when planning a backup schedule is prioritization of data. Not all data is created equal and a tiered backup strategy that restores the most critical applications first will get you back in business faster and cut data storage costs.
