“Invalid header marker”

We need a little more detail:

  • What version of Duplicati are you running?
  • What OS (Windows, Linux, MacOS)?
  • What destination are you using (local, FTP, Google Drive, …)?
  • Can you copy / paste more of the actual error message?

Here’s a description of the “Invalid header marker” error likely meant to somebody using Dropbox:

You should be able to click on the error in the Duplicati logs to get details about it including the name of the file with the problem. If you can, then check the destination directly to make sure the file isn’t 0 bytes in size.

If you use WebDAV to look at file duplicati-ieb1200ced4fc4b7a947ea3b322e09d2c.dindex.zip.aes can you tell what size it is?

If you can open it in a hex editor does it start with the letters AES?

This message likely came from recreating the database, is that what you are trying to do when the “invalid header marker” error happens?
