Hi,
today I had my first error with my duplicati backup which was the following:
“Fatal error
Duplicati.Library.Interface.UserInformationException: Found 1 files that are missing from the remote storage, please run repair
bei Duplicati.Library.Main.Operation.FilelistProcessor.VerifyRemoteList(BackendManager backend, Options options, LocalDatabase database, IBackendWriter log, String protectedfile)
bei Duplicati.Library.Main.Operation.BackupHandler.PreBackupVerify(BackendManager backend, String protectedfile)
bei Duplicati.Library.Main.Operation.BackupHandler.Run(String sources, IFilter filter)”
I’m on 2.0.3.3_beta_2018-04-02.
I’ve tried the repair function which had no effect at all.
I’m a bit scared about the delete and repair function because my 700GB backup is on a remote side and my upload is rather slow…
Edit1:
I did a “list-broken-files” procedure with the following outcome:
No broken filesets found in database, checking for missing remote files
Listing remote folder …
Marked 1 remote files for deletion

Return code: 0
Edit2:
Afterwards I ran the “purge-broken-files” command with the following answer:
No broken filesets found in database, checking for missing remote files
Listing remote folder …
Marked 1 remote files for deletion

Then I started the backup process again.
Now everything is fine… Problem solved
