We have a BE15 and we plan to migrate to BE16
the BE15 is Local backup Exec with Remote SQL server 2014 instance .
our perpose to migrate to BE16 it's to use Azure Storage Account to store our Full Backups Files .
My question , it'is a good idea to do this ?what is the best way to use a Cloud Storage in this Case?
There are Pros and Cons for using Cloud Storage for storing Backup Data. Its hard to give a blanket statement on whether it is right for you or your organization.
Some of these are covered in the following Veritas Best Practices document. It was written with BE15 in mind, but the principles would be the same for BE16 and Azure.
As far as the migration from BE15 to BE16, that should be pretty straight forward and I would not expect any issues.
