Hello. I’ve deployed Duplicati in docker compose version 2.2.0.3 - 2.2.0.3_stable_2026-01-06 in a NAS with Openmediavault 8.0.8-1 (Synchrony) x64 because I think it is a very good solution for back-up. The whole process has gone well. I have configured a backup of tests with 1 small file. The problem comes to me to do the restore of tests that are not performed and gives the following error:
-
2026-01-25 16:45:22 +01 - [Error-Duplicati.Library.Main.Operation.Restore.VolumeDownloader-DownloadError]: Error during download
IndexOutOfRangeException: Index was outside the bounds of the array. -

Both the backup as a restore is performed on an external USB hard drive 8 TB and the folder where you would leave the restore has the following permissions:
I have checked the folder where it should stop the restore and interestingly creates the file that I’m testing peo and white with size 0.
Any help is welcome…..
Best regards
