VCB on standalone ESX 3.5 and Backupexec 12 without virtual center
I have a single ESX 3.5 server in a site not attached to virtualcenter. I know it's possible to run vcb without centralized storage by using the new "NBD" switch. I've tested it and it seems to work. So my questions are:
1. vcbmount seems to work if I point directly to the ESX 3.5 server. So what's the benefit of pointing it to a virtualcenter server? Assuming virtualcenter is on another site away from the local esx target should I even point vcb to it?
2. I have a standalone server running backupexec 12 and vcb. When i run the vcbmount script from the pre/post option it fails. However, the same batch file works when i run manually.
