This issue has been posted about several times, but I don’t see any resolutions yet. My laptop has been getting a blue screen of death (Windows 10) lately. I later discovered it was bad RAM. As I was getting ready to run some hardware tests, I did a manual backup with Duplicati as a precaution. That’s when I noticed Invalid Passphrase issue had recently started.
I don’t see anything new that caused it to start in the logs. Assuming the BSODs are maybe to blame. I was not able to complete a new backup, or recover any files, or repair the database. I was using version 126.96.36.199. The backups would run a long while before finally throwing the error at the “deleting unwanted files” stage.
Error: Failed to decrypt data (invalid passphrase?): Message has been altered, do not trust content
I confirmed I could manually decrypt the files using AESCrypt for Windows, so I know the password is valid. I have it stored in my password manager.
I recreated the database which completed successfully. This allowed me to complete one backup without any errors/warnings on the profile. It also allowed me to restore files from old backups which did not work before. Any subsequent backups received the error again. I have upgraded to version 188.8.131.52 and done a recreate and successful backup twice now, with all subsequent backups failing.
Anybody have any ideas of what can be done without starting a new backup? This backup is over 200GB off-site which would take me 3 days at full bandwidth to re-upload.
