Hi, what is differences between 'snapshot client' backup and regular backup? In documentation there is written that snapshot client backup makes point-in-time presentation of drive and dont lock drive. So what? Any kind on backup, example standard or ms-windows also make point-in-time presentation and also dont lock drive. Microsoft integrated VSS never lock drive. And when I make regular standard backup with netbackup, then in client options I can choose to use VSS or symantec own open-file-provider. Also, with 'snapshot client backu' there is not possibility to save windows system-state. This is strange, because windows VSS always makes also system-state through VSS writers. And when I use Netbackup regular backup, then I can include system-state. But system-state can only made through VSS, so it is also made through snapshot. Where is the point of term "snapshot client"?
