Jobs targeting an S3-Compatible repository fail with either of the following errors: Error: S3 error: Content-MD5 HTTP header is required for Put Object requests with Object Lock parameters Code: InvalidRequest Agent failed to process method S3 error: Checksum Type mismatch occurred, expected checksum Type: null, actual checksum Type: sha256
Starting in Veeam Backup & Replication 13.0.1, the software now utilizes the SHA256 algorithm for hash calculation when signing API requests to S3 storage systems. SHA256 is supported by AWS (as stated in their documentation), but not all S3-compatible storage systems implement SHA256, instead relying on the obsolete MD5.
Option 1: Enable SHA256 Support on Storage For on-premises storage devices, review the settings to determine if the option to use compliant SHA-256 hashing is available. If this option is not available, we encourage you to contact your storage vendor for assistance in determining if newer firmware is available that includes SHA-256 hashing or if it will be available in an upcoming firmware release.
