BackupPC uses 1000MB (not 1024MB) for "G", while df uses 2^30 (1024MB). So the BackupPC number will be 2.4% higer. I should probably change BackupPC to use 2^30 too; I don't know why I picked 1000 * 2^20 - maybe that's what disk drives use for raw capacity? The pool size is the sum of the number of blocks used for each file in the pool. In general that should be less than reported by "df" since the pc directories contain full directory trees (just containing hardlinks of course) and Xfer log files that occupy some disk space. So your results above make sense if you have copied the pool but there aren't too many backups saved.
