I didn't see what you meant, but you were right, in the Exclude section was:

Wild = "[A-Z]:/Users/*/AppData/*"

Albeit that is certainly a mulligan - even if I have No excludes at all against the AppData directory - strangely, Bacula will just not back anything up but folder names within that AppData directory - and not even all folders. 

I can specify */AppData/Roaming, or */AppData/Local - it doesn't matter, it doesn't even Try to back them up!

I will conduct more experiments on this, but so far - even adding an Include of a WildDir against all directories within AppData just isn't helping.

I have abolished all AppData excludes, and even with the following as the only includes, all it will back up is */AppData/Local/History - Nothing else:

      WildDir = "[A-Z]:/Users/*/AppData"

      Wild = "[A-Z]:/Users/*/AppData/*"

      WildDir = "[A-Z]:/Users/*/AppData/Local"
      Wild = "[A-Z]:/Users/*/AppData/Local/*"
      WildDir = "[A-Z]:/Users/*/AppData/LocalLow"
      Wild = "[A-Z]:/Users/*/AppData/LocalLow/*"
      WildDir = "[A-Z]:/Users/*/AppData/Roaming"
      Wild = "[A-Z]:/Users/*/AppData/Roaming/*"

On a side note, however, I'm a tad overdue for a Bacula Director upgrade, so maybe there was a fix they already knew about in regards to this - especially since VSS is floppy on the version I'm running. We'll see.
