Are there any known issues with Differenced/Partial file backup support?
I'm using AlphaVSS to try a differential backup. I take a full backup for the Sql Server Writer. I think make some changes to one of the databases and attempt a differential. In the diff, I set the previous backup timestamp for each component
using the timestamp in the full backup's components document. I then prepare for backup (state of Diff), perform the snapshot, and look at the Component related to the database I changed. DifferencedFiles is empty. If I enable Partial support,
the PartialFiles collection is empty.
Is there some mechanism I'm missing to detect which files are changed?
