Hello @pierre-gilles,

After a reinstallation I’m having trouble restoring my backup; I have a message in the Gladys logs:

Hi @Nagromdark 🙂

The error says «&nbsp;bad decrypt&nbsp;», which means your recovery key is not correct.

Are you sure you entered the correct recovery key?

I was afraid you’d tell me that… But yes, I’m sure about the key — I stored it in KeePass. Unless it changed and I forgot to note it down… So is it over, have I lost everything? 😢

The recovery key never changes, unless of course you reinstall Gladys from scratch.

If I were you, I’d try restoring again, making sure that when you copy-paste you don’t accidentally include a space or a weird character at the beginning or the end.

If that doesn’t work, there’s no magic, it’s lost… 😕 You’re the only one who has the recovery key, and without it it’s impossible to decrypt the backup.
