Bob:

Something must be different. We use an unattended process that creates the two backups one after the other, Datacare and Toolkit, in different networks and disk sizes. Datacare fails sometimes, Toolkit backup never fails. It is probably that the network is slower when Datacare fails, but it doesn't happen to the Toolkit backup. It is unfortunate that we cannot rely on Datacare backup, because Toolkit doesn't have the feature to clean up its own old backups.
