I have indeed installed SP5. Did that back in February 2010. Then, installed hotfix 70 on top of that in July 2010.
It used to be the case that you could easily find service packs and hotfixes for Symantec Backup Exec. Now, you have to wade through a cumbersome search feature that usually either provides items that are not hotfixes or service packs, or it provides results that appear to be unreliable. Why would a search return a link to hotfix 63, but fail to give a link to hotfixes 64 through 70? I have no confidence that I have the latest patch based on what I can see through the Tech Support portion of the Symantec website.
Does anyone know of a way to get a comprehensive listing of all service packs and hotfixes for a particular version of Backup Exec?
