There are 4 aliases in there:

MacIntosh HD (4kb) and the 3 partitions of the external drive (each 0 kb).

Btw, I did a smart-update from the MacIntosh HD to the backup-partition of the ext. HD again using the 'backup all files' sript and now the size of the ext. HD partition used for the backup is 42.18 GB of 149.88 GB instead of 33.75 GB (after the initial backup using the 'backup all files' sript and the "Erase ... then copy files from ..." option). The only other change I made was the 'successful-completion" setting: Instead of 'Do nothing' I now chose 'Set BackUp as startup-disk'.

That reduces the discrepancy between the internal HD and the backup-partition of the ext. HD down to roughly 4 GB.

What happened...?

Is it now save to rebackup from the ext. HD to the internal HD?

Edit: I checked the file-sizes with WhatSize and - dahdah - the private/var folder contains 4.09 GB of which there are 3 GB in 'vm', another 1.07 GB in 'tmp', 11.1 MB in 'log', 6.99 MB in 'db', etc.. Are these all temporary files which I won't need for rebackingup?
