Hi Bob,
Try the newest 6.5 interim one-click I put together yesterday:
http://www.aidaweb.si/downloadIn this release the hourly snapshot together with image backup is
switched off by default. To enable it, evaluate:
AIDASite default hourlySnapshotEnabled: true
The hourly snapshot is used for image based persistence while image
backup provides additional protection against possible image corruption
of any cause.
Image backup troubles on Windows seems to be related to package
OSProcess running on Windows. I don't know in which state is OSProcess
currently on this regard.
Best regards
Janko
