The Database Archive routine first checks the database for possible errors, and stops if it finds a problem. Which is good, as a backup that contains errors isn’t desirable.
Run Tools > Verify & Repair.
If there are errors that can’t be repaired, it’s probably time to run Tools > Rebuild Database. Afterwards, check the Log (Window > Log) for a list of files that may have been excluded. Note that you can save the Log for future reference.
verify and repair did it. Thank you. Sorry, it must have been a pretty dull question, but I never did export anything from DTPO and I just start to use it on a regular basis. Although I own for years now (from DT on)
Bad news.
The repair command repaired the Database, but I couldnt archive it nonetheless, so I did a rebuild. Took a while. Tried to archive the DB, same as before at the very beginning. Repaired it again, but DT couldn’t repair one fault.
I will copy the relevant data manually and import it to a new database on the Macbook. Besser als nix.
