Duplicati is totally failing to run

Duplicati is totally failing to run any backup. I have two scheduled backup tasks

Manually running one task produces

Found 2 files that are missing from the remote storage, please run repair

Running repair by clicking the button leads to the following error
Got 6 error(s)

But I cannot find any further information or find any way to correct the error resume my backups.

I believe this this all started when one of the mirrored drives in my NAS failed and took my NAS completely offline - it would not even switch off from the power button. I don’t know whether it failed during a backup or not. I have had to removed the faulty disk drive to get my NAS is working again (but no longer mirrored) but since then I have totally failed to be able to run either of my backup tasks since that date. I think I have tried the recovery options described but to no effect.

My NAS is going to be replaced (it is quite old) but I do have about 2 months of backups on it since I started to use Duplicati. I am now beginning to doubt if Duplicati is an appropriate choice for my backup and should I be looking for an alternative. I need to resolve this issue as soon as possible - please help me.

I wonder if some of your backup files got corrupt when you had a NAS failure. Can you share the full errors that you see when you try to do a repair? (What are the six errors?)

To help protect you from a failure of your primary backup storage, you might consider syncing the backup data to another location. This is the approach I use. My backups go to my NAS, but then my NAS syncs to cloud storage (B2). This way I’m almost certain to never lose my backup data…

I have tried to upload a PDF containing the screen shots but that does not appear to be allowed. I have copied the error log below. I had just run repair.

My real concern is that I am now unable to run a backup at all. It is very disturbing that a crash of my NAS should prevent further backups and quite possibly recovery of existing backup data. When I removed the failing disk (and hence broke the NAS mirror) all my other files were intact.

As I am about to replace my NAS I can just about live with the error but I will have lost all of my backups for the past two months since I first tried Duplicati. I may have to revert to my previous backup solution which, at worst, could probably only lose a single file and could not prevent future backups which is the situation I am now in. It would be impossible to break the backup from running. I am guessing that the clever optimisation of Duplicati has led to these issues. I have not tried to restore any files but i am guessing that this would not be possible if the master files are not recoverable.

Duplicati.Library.Interface.UserInformationException: Found 7 files that are missing from the remote storage, please run repair at Duplicati.Library.Main.Operation.FilelistProcessor.VerifyRemoteList(BackendManager backend, Options options, LocalDatabase database, IBackendWriter log, IEnumerable1 protectedFiles) at Duplicati.Library.Main.Operation.BackupHandler.PreBackupVerify(BackendManager backend, String protectedfile) at Duplicati.Library.Main.Operation.BackupHandler.<RunAsync>d__20.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at CoCoL.ChannelExtensions.WaitForTaskOrThrow(Task task) at Duplicati.Library.Main.Controller.<>c__DisplayClass14_0.<Backup>b__0(BackupResults result) at Duplicati.Library.Main.Controller.RunAction[T](T result, String[]& paths, IFilter& filter, Action1 method) at Duplicati.Library.Main.Controller.Backup(String inputsources, IFilter filter) at Duplicati.Server.Runner.Run(IRunnerData data, Boolean fromQueue)

Ok, if all your other files are in tact then maybe your backup data is ok as well. It could very well be that the NAS failure occurred while a Duplicati backup is in progress, so right now we just need to fix the out-of-sync state between your local Duplicati database and the back end storage.

Your screen shot didn’t come through. Can you try again? And I see your error text telling you to run Repair. Can you show me the full error text you get when you attempt a Repair?

Run backup

Found 7 files that are missing from the remote storage, please run repair

Run Repair

Got 7 error(s)

I have attached the log data - i hope this is what you need

I hope this is what you need.

There are two backup tasks - both fail and this is just one of them

Is this file present on the NAS?

duplicati-b1aac112a0c5b49e38b306df84e7f62b1.dblock.zip.aes

You should be able to just paste these from the clipboard into the forum post.

Not sure what master file you mean. Database can often be recreated. Lost destination files mean part of the backup is gone, You use The AFFECTED command to see which source files are affected by loss of some destination file (affected means broken). There’s also list-broken-files and purge-broken-files. See Disaster Recovery. It’s definitely more complicated than simple backup programs, but has its advantages.
Going down the list, there’s also Duplicati.CommandLine.RecoveryTool.exe which handles damage better.

This looks like an old log of backup on the 18th. Errors often log in About → Show log → Stored.
Here’s an example from a Repair I ran after hiding a file (and I pasted .png from clipboard here):

I like how Repair names names. Backup doesn’t, but you can see About → Show log --Live → Warning

Yes it is. It took some finding!

Here is one of the log files - I think this is from my scheduled backup. It is asking me to run repair. I have not done this for this backup but it has had no effect do far.

I am very new to Duplicati and have not yet found my way around the log files and how to access them. I am quite experienced with Windows (from around 1986 - beta copy of Windows 1) but less so with UNIX/Linux.

If it runs like mine, it should at least tell you what the missing files are. For Backup, use live log per above.
list-broken-files will I think automatically notice missing files. It actually doesn;t work so well with this

where a file looks corrupted (maybe partial, hard to say without more info). Corrupted files can be deleted unless you want to try to look inside with file tools (in which case just move them out of the backup folder).

Once you find the missing or damaged (such as above) file names, date of the file may suggest when that happened, although if there’s a chance that NAS file damage was involved, date stamps might not reveal.

If it suits you, you could open a copy of the Database with DB Browser for SQLite to get some information about given files to see when they were made (old damage, or new). See Remoteoperation table and use EpochConverter on the timestamp. Same data can be had in a GUI view at <job> → Show log → Remote, however searching is easier in the DB browser via the Filter column. This exercise won’t fix anything but might help understand what went wrong sometime earlier. log-file data would be better, but wasn’t created.

To resume backups, you probably need a damage assessment. Missing files are missing, damaged ones can be deleted. If there are extra files then situation gets less clear, otherwise it’s probably list-broken-files and purge-broken-files to trim out some versions of some files, and get the backup back into backing up…
