[rdiff-backup-users] Measuring transfer size

[Torrance]

Hi all,

I have a (possibly) really simple question: is it possible to work out  
from the session statistics the total amount of data transferred  
during a backup?

For example:

--------------[ Session statistics ]--------------
StartTime 1249920926.00 (Tue Aug 11 04:15:26 2009)
EndTime 1249921122.67 (Tue Aug 11 04:18:42 2009)
ElapsedTime 196.67 (3 minutes 16.67 seconds)
SourceFiles 2
SourceFileSize 482343704 (460 MB)
MirrorFiles 2
MirrorFileSize 482171086 (460 MB)
NewFiles 0
NewFileSize 0 (0 bytes)
DeletedFiles 0
DeletedFileSize 0 (0 bytes)
ChangedFiles 2
ChangedSourceSize 482343704 (460 MB)
ChangedMirrorSize 482171086 (460 MB)
IncrementFiles 2
IncrementFileSize 4839591 (4.62 MB)
TotalDestinationSizeChange 5012209 (4.78 MB)
Errors 0
--------------------------------------------------

I would have guessed it was the IncrementFileSize + the NewFileSize,  
ie. in this case 4.62MB (or probably this figure gzipped).

Is this correct? I have very limited data allowances and I need to be  
able to monitor nightly backups of some fairly large datasets.

Thanks in advance,
Torrance
