I’m trying Duplicacy with the final goal to perform backups on a remote sftp server.
For testing purposes, I’ve created an encrypted backup using duplicacy CLI on a Linux x64 machine with a local USB drive as storage.
In order to test various environments, I’ve then attached the USB drive to a Windows 10 x64 machine and created here a repository using again the USB drive as storage, then I attempted to restore the previously created backup.
What happens is that I’m asked for the encryption password, I type it in, then the restore process tries to start but suddenly stops with the message “Failed to decrypt the chunk f69617df28e40f624fadd7ce7efbf085043b0e8d5d6ac91eeee7cc21c00b0b51: cipher: message authentication failed; retrying”, it retries four times then aborts.
I’m sure the password I’ve entered is correct, if I try to type an incorrect password I get immediately this message “Failed to download the configuration file from the storage: Failed to retrieve the config file: cipher: message authentication failed”, which is similar (the password isn’t recognized), but here it fails immediately, while giving the correct password it fails when attempting to restore the contents of my backup (while decrypting the chunks).
So my guess is that backups created under Linux are incompatible with Windows (and vice versa). Is this true? If not, what else can be the cause of my issue? Can it be solved?
