Wherever data is, however it is stored you still need to backup.

Cloud Backup, Hybrid Backup, Local Backup. Virtual, Physical, Application Level. Wherever data is, however it is stored you still need to backup.

 Backup is still as relevant as ever, data is the life blood of any organisation and without it a company can cease to exist. So how do you back up data in the modern IT infrastructure when data can be either on premise, in the cloud, or a mixture of the two, Physical, Virtual and data rate changes could be in the TB’s daily depending on your type of business.

There is also the grey area of Backup and DR, they are both different but a lot of Backup vendors are developing DR functionality into their solutions whether that be onsite or offsite DR.

Regardless of how you store data you still need to remember the fundamentals.

Fundamentally Backup is storing your data in a location different to the primary data for as long as the company needs it. DR is restoring and presenting that data at the speed needed, to the location required. Pretty basic eh? What some companies are starting to forget is regardless of how simple the above is, the 321 rule below is still as relevant as ever regardless of where the data is, what it is on and how much of it there is. Recent issues such as the data outage issue at the ATO http://www.zdnet.com/article/ato-services-begin-to-return-again/ show that issues with a company’s failover plan from their primary systems can cause major issues but they still had a Backup plan!! Data was backed up using the 321 rule. They had the data on different media and in an different location to their primary data. Without this they could never have rebuilt their systems. The fact it took longer than expected was a failure in their DR solution, not their Backup solution.

The 3-2-1 backup rule implies that you should:

  1. Have at least 3 copies of your data
  2. Keep these backups on 2 different media
  3. Store 1 backup offsite 

So regardless of where the data is, what it is on, how it is accessed or how much there is the 321 rule should still be followed.
