I get this error:
2019-08-26 21:29:11 -05 - [Error-Duplicati.Library.Main.Operation.BackupHandler-FatalError]: Fatal error System.Data.SQLite.SQLiteException (0x80004005): unknown error No transaction is active on this connection en System.Data.SQLite.SQLiteTransactionBase.IsValid(Boolean throwError) en System.Data.SQLite.SQLiteTransaction.Commit() en Duplicati.Library.Main.Operation.Common.DatabaseCommon.Dispose(Boolean isDisposing) en Duplicati.Library.Main.Operation.Common.SingleRunner.Dispose() en Duplicati.Library.Main.Operation.BackupHandler.<RunAsync>d__19.MoveNext()
It is persistent after database recreate (delete and rebuild); actually after recreating the database, the first backup completes without problems, but the second one gives this error again.
This error is different from what others report: there is no rollback here, there is no “Unexpected number of remote volumes detected: 0!”, there is no “cannot commit - no transaction is active”, no other error message before this one.
The backup is to a local disk, which has 0.5 TB free (the source disk has 100 GB, with a handful of tiny files to be updated from the previous backup – several MBs or less). The TEMP disk has 2 GB free.
I have several backup sets, but only one has this problem. They all have the same configuration (backup to the same local disk and with the same TEMP disk), differing only in the source directories.
How can I solve the problem, other than discarding the existing backup?
(BTW, any way to have more descriptive error messages, such as the values of the arguments of the function calls in the trace?)
