Suddenly one of my backups to google drive started to fail due to the error in the title, as logged below:
2019-06-18 09:49:05 +02 - [Error-Duplicati.Library.Main.Operation.TestHandler-FailedToProcessFile]: Failed to process file duplicati-20190618T073640Z.dlist.zip.aes
Duplicati.Library.Main.BackendManager+HashMismatchException: Mancata corrispondenza hash nel file "C:\Users\Myname\AppData\Local\Temp\dup-b86434d2-ed85-4889-b962-9b56e547e4c2", hash registrato: +KAA4zvZPCQcZkQZaP7ylOeMOwZ/5+cV06eBYjn+P7U=, hash effettivo x63Iat6swBjAH8ly0Pkd/KsbYYEQsEalzB/03xkpcks=
in Duplicati.Library.Main.BackendManager.GetForTesting(String remotename, Int64 size, String hash)
in Duplicati.Library.Main.Operation.TestHandler.DoRun(Int64 samples, LocalTestDatabase db, BackendManager backend)
I tried to follow some hints, the last one suggesting to delete the duplicati-*.dlist.aes file and then repair the database, but the error reappears at the next backup.
Since the thread is more than a year old, I’ve opened a new one (I hope to have made the right choice).
