There has always been a golden rule of backup “The 3-2-1 rule” simple backup strategy: Three copies of your data, in two different formats, with one of those copies offsite. These three copies ensures redundancy


Many companies moved away from tape as primary backup to hard disk, using tape as a secondary. But cloud backups are gaining ground and becoming the new norm, Admins are now backing up first to disk and then to the cloud.




The idea of backing up with a cloud storage has some great benefits in theory, it can provide an offsite copy of your data should you need it. Without having to retrieve tapes or drives from an offsite facility. The backup goes right over the Internet to cloud storage.


The reality is not always so nice. The cost for Cloud backups can be expensive. You will also need to deal with limited bandwidth, and as your backups grow, the cost will increase.


If your Infrastructure in the cloud, don’t think you’re backed up. A recent article about Rackspace Cloud SQL not being able to fail between data centers sent several customers to Amazon’s offering.


There are a ton of cloud backup options out there, some of which offer simple cloud storage that you can just dump raw data into, and some provide the kind of backup and recovery capabilities familiar in the data center. Don’t make the mistake of thinking all cloud backup offerings are the same.


Most administrators will agree a hybrid approach might stratify you backup strategies.


Two different solutions: one to handle the backup and the other to hold the backup. An example could be Microsoft Azure for your storage provider with a front-end tool like Veeam Cloud Connect to manage the backup of VMs.


Veeam Cloud Connect offers an SSL backup (deduplicated and compressed) to a partner service provider (Azure, for example) and optionally includes WAN acceleration to help offset the bandwidth issue. It also offers “forever incremental backups” (deltas) that allow for less data to travel to the cloud. You can also do traditional grandfather-father-son (GFS) backup. End-to-end encryption of the data ensures security in transit and in storage.


Commvault’s Unified Cloud Data Protection has something similar.


Then there’s Nasuni, whose hybrid cloud storage offering combines local storage controllers and cloud storage..


No matter what solution you implement, it’s important to have a clear understanding of pricing (including storage costs and fees for storing and retrieving your data).


Once you have an understanding of what is available and how you can leverage it the cloud could be you friend.


Last note and backup, be sure to test your backup strategy, there is nothing like retrieving data that is not there.
