But if you take a snapshot without VSS writer functions, I tend to believe that there is a serious potential that relevant information is still only in RAM and not written to disk. This would get lost in the snapshot. I may be wrong, but my understanding of a VSS writer is that all transaction and log files are flushed to disk prior tot he snapshot.
