Thanks for your help, but also there I cannot seem to find the answer to my question.
More info: Since my HD had to be replaced, I made two backups. One was the TM backup (which had existed for months and was up-to-date). To be sure, I made a second one, with CCC.
When I got my iMac back, I used the TM backup to restore my system. But I was shocked to find out that my system suddenly had upgraded to Lion, which I had just downgraded from to SL couple of months ago.
So I removed everything, made a fresh re-install of SL using the install DVD, and then I used CCC to get back to the day I brought my iMac to the store.
But now, when I fire up TM to go on with making backups, it claims it need some 500 Gb (that's a full backup) to make the backup on the same old external HD where all the old backups reside. While practically nothing has changed yet on my iMac.
So, apparently, TM does not understand that it just has to make an incremental backup.
Of course, I can format the external HD. But that is not what I have been making TM backups the past year for.

OK. Rather than delve into all of your combinations, if you made a CCC bootable clone of what you had before getting the HD replaced, the simplest thing to do is boot with the clone, launch Disk Utility, wipe the new HD, and restore the clone. Ignore TM for the moment. Once your machine's running on the int HD exactly like it was before, then go an investigate the TM stuff. I don't use it, so Pondini's guide is the only thing I can point you to. Since your HD changed, so it comes with an universally unique ID (UUID) and TM needs to redo the backup to reflect that, but the details are beyond my ken.27" i7 iMac SL, Lion, OS X Mountain Lion (10.8.2), G4 450 MP w/Leopard, 9.2.2
