Ii am using Duplicati on a Raspberry Pi 4 in combination with rclone to backup some data from my OneDrive to a network share on my NAS device. I have setup two backup jobs for two different top level directories of my OneDrive space, these jobs run on a daily base. Every day I receive a number or warnings (around 35) from each of these jobs, the warning are all similar to this one here:
*** 2021-01-25 18:00:07 +01 - [Warning-Duplicati.Library.Main.Operation.FilelistProcessor-MissingRemoteHash]: remote file duplicati-b5385c7c127d74a7a8aa4eba9419b2b37.dblock.zip.aes is listed as Uploaded with size 34930688 but should be 52415917, please verify the sha256 hash “GBbtipmfTYDwOGSb6619Qqdv3xOBgZqAFtkjo6XQnmw=”**
I also get some error messages from time to time like
*** 2021-01-26 06:05:15 +01 - [Error-Duplicati.Library.Main.Operation.TestHandler-FailedToProcessFile]: Failed to process file duplicati-b174c8b79ce1d429083887aba55bf0cc8.dblock.zip.aes**
*** 2021-01-22 23:21:06 +01 - [Error-Duplicati.Library.Main.Operation.RestoreHandler-PatchingFailed]: Failed to patch with remote file: “duplicati-b85ae24dfa8234f4e8c36d525ee284a45.dblock.zip.aes”, message: File length is invalid**
I was trying to do a full restore of a backup to a local destination which did not generate any error message but I am a bit worried about the reliability of my backups. Does somebody know what may have caused these permanent warnings / errors and how to identify the root cause to solve this?
