[rdiff-backup-users] TotalDestinationSizeChange?

[Kevin Horton]

I'm puzzled by the meaning of "TotalDestinationSizeChange" in the  
session statistics.  The only documentation I can find for it is in  
the rdiff-backup changelog, which says that it is "(total change in  
destination directory - mirror change + increments change)".

I started a new repository last weekend on an external drive that I  
store at a friend's house.  Yesterday I did the second backup to that  
drive, and the session statistics showed a negative  
TotalDestinationSizeChange.  What does that mean?
