Stuck in Verify ... Repair Loop

Hi All,

I did a backup to an offsite SFTP server and have had some issues I seem to be unable to recover from.

There were some messages about not being able to upload a file after 5 retries, but the thing that was odd was the timing with other messages. It was something like the below (from older to newer). It was odd to me that it said it couldn’t upload a file and then seemed to successfully rename it. It would then try to upload the newly named file and repeated this pattern until the 5 retry limit was reached. This happened for multiple files.

Operation Put with file duplicati-b57177ee5e3da412db1f55d254e253eba.dblock.zip.aes attempt 1 of 5 failed with message: Client not connected.

Renaming “duplicati-b57177ee5e3da412db1f55d254e253eba.dblock.zip.aes” to “duplicati-b28b599965e4147cbac30a0aa5dfe5985.dblock.zip.aes”

And then other unrelated files reported issues (in newest to oldest order):

  • Found 5 files that are missing from the remote storage, please run repair

remote file duplicati-b8d4ab807af754640923eda4003a884bd.dblock.zip.aes is listed as Uploaded with size 36537840 but should be 52375789, please verify the sha256 hash “Nwxx+V2ms76YvtLhK+jevAQ7Oqg6Q/SGbnZbli/mj9Y=”

Since then I seem to be stuck is this unrecoverable loop of instructions:
Run repair, error, run verify, run repair.

So I run the repair then I get this:
Operation Get with file duplicati-b8d4ab807af754640923eda4003a884bd.dblock.zip.aes attempt 5 of 5 failed with message: File length is invalid

Failed to perform verification for file: duplicati-b8d4ab807af754640923eda4003a884bd.dblock.zip.aes, please run verify; message: File length is invalid

Then I run verify and get this:
Fatal error

Duplicati.Library.Interface.UserInformationException: Found 2 files that are missing from the remote storage, please run repair

On a side note, the upload was much slower than expected, the UI showed 3.5 MB/s and windows task manager showed a sustained 30 Mbps. The connection is capable of 150 Mbps and can see something close just doing a normal transfer outside of duplicati. I measured 12 and 13 MB/s with a 600 MB file and a 90 MB file.

Any help is appreciated.

Thanks.

Does anyone have any insight?
