I am currently reading reviews for this type of product, and I am desperately avoiding this one product because Symantec has provided the worst support I have ever experienced.  Not on one occasion, but several over the last year.  I was on hold for support on our corporate antivirus solution for 4 hours one time, and we pay for platinum support (which is very expensive)!  Most of the time I have to wait for 40 minutes on hold and then there is no follow-up on the case, if you have an additional question you have to pick up the phone, get back into the queue and repeat the process.

Veritas support for backupexec is slightly better but has gone downhill also since Veritas bought them; if you have a problem that is urgent, expect to resolve it yourself, it will be faster.

Bottom line is that Symantec support is very inaccessible and this is just not acceptable for business-critical applications, even if the product is good.  I am going to keep reading reviews.
