You can just copy the data.mdb file if you want to make a backup. There is no reason to use monero-blockchain-export.

Which would make incremental backups to an external source much harder. Again, I thought this tool was a solution to make easy, incremental backups.

Can you delete blockchain.raw and try to export it again, does it stop/error at the same height?

I'll have to let it run for a while. It slows down quite a lot even though it's on a local SSD.
Once it's done, i'll let you know. I'll get to it in probably 12-24 hours.

The new export has been running for a few hours now and is almost finished. I also briefly stopped the export in between and turned on the Monero node to let the blockchain synchronize. After a few minutes of synchronization, I turned off the node again and restarted the export, which then continued without any problems. It really seems as if the first export was corrupted for some reason, even though the export tool did not give me any error message.
UPDATE:
Seems like i replied too early. After now fully synchronizing my Blockchain and trying to update the blockchain_new.raw exported file, i get the same error again.
