I’m unable to solve this problem.

```

I’ve tried repair, delete+repair, purge, purge broken files, verify: none works.  
No throttle option, no need for it: the destination is a usb disk attached to the router.  
Any hint?  
Thanks.

The hint is what you got in the one-line summary, which omitted the detailed error.  
Some problem is showing up with those files, maybe while [verifying backend files](https://duplicati.readthedocs.io/en/latest/03-using-the-graphical-user-interface/#verifying-backend-files).

Can you try for a more detailed report from About → Show log → Live → Retry?

[The TEST command](https://duplicati.readthedocs.io/en/latest/04-using-duplicati-from-the-command-line/#the-test-command) has more. Did you set up [–backup-test-samples](https://duplicati.readthedocs.io/en/latest/06-advanced-options/#backup-test-samples) or similar?  
I’m not sure if the three rather-close-together errors were from one backup or not.

I suppose you could also see if the file still makes sense or if it’s been malformed.

[AES Crypt](https://www.aescrypt.com/) should decrypt it. If you prefer CLI, use Duplicati’s SharpAESCrypt.exe.
