Note that, even when running as an admin user, sometimes timedog and TimeTracker need to be run as root to see all files. When not doing that, one might for example not take the backups of MySQL logs and data into account:

cd "/Volumes/Backup of Palahala/Backups.backupdb/Palahala/Latest"
sudo ls -l "Macintosh HD/usr/local/mysql-5.0.51a-osx10.5-x86"
[..]
drwxr-x---@  6 _mysql  wheel    374 Jul  2 20:05 data

In those cases both timedog and TimeTracker will report a lower total backup size and less files than the backupd logs in Console (easily shown using the Time Machine Buddy widget), or the (different) log that is kept in the hidden .Backup.log file on the backup disk.

So, for timedog:

cd "/Volumes/Backup of Palahala/Backups.backupdb/Palahala" 
sudo ~/Downloads/timedog

Likewise, for TimeTracker:
