Revolving around the core of technology
Hoping at some point the Exchange Plug In can backup Exchange database like other traditional backups and not have to do PST dumps which can take quite some time in larger Exchange environments and then still require the transfer of the PST files. Not very efficient.
I agree. However, have you tested a simple VSS backup copy of the db files? I wouldn't be surprised if it worked fine. Still not ideal but would be better than PSTs.
