Amazon S3 Backup Validation fails
I'm getting the following error when validating a backup destination to Amazon S3:
Validation for transport "AWS S3" failed: Could not download test file: Computed and Response MD5's do not match: 1d3b2064f95e43ca602c1b7c9be3f78b : 13d1d0efbcd3932712a57b5ae07a67f7 at /usr/local/cpanel/Cpanel/Transport/Files/AmazonS3.pm line 299. [backup_destination_validate] version [1]
The test file is indeed being upload to the S3 bucket but it is not getting deleted after the test.
Thank you

Hi. No this does not help. I read this thread before posting. This thread involves the bucket name and the fact that it cannot upload the file. My setup uploads the file fine, but states "Could not download test file: Computed and Response MD5's do not match" I have verified the file does get uploaded and can be downloaded via S3 console. Do i need special perms set on the bucket? I would think not if WHM is using the API and the creds supplied. I have searched and read dozens of posts regarding S3 validation failures but none of them are related to this error. 0 -
Hi @BillBuilt I found one other instance of this occurring and in that instance it seems there the request for the validation object was returning a 301 redirection and the md5 hash was invalid due to the hash being calculated based on the 301 headers rather than the contents of the actual file. There's some more information on how and why Amazon S3 sometimes requires redirections in the following article: Request Redirection and the REST API - Amazon Simple Storage Service In the other case, they had use KMS encryption at some point, changing the encryption type to 256-bit encryption resolved the issue. 0 -
It appears my issue was indeed the KMS encryption. Changing to AES-256 seemed to resolve it. Thanks! 0
