Applicable to:

  • Plesk for Linux

Symptoms

  • Upon creating backup and uploading to Backblaze S3-like storage, the backup fails and the following error can be seen in Tools & Settings > Backup Manager:

    Unable to create the remote backup: Transport error: Extension transport: ext://s3-backup/server/: Unsupported header 'x-amz-checksum-crc32' received for this API call.

Cause

AWS has updated the AWS-CLI, which changed some parameters.

Resolution

  1. Log into your Plesk server.

  2. Edit the /usr/local/psa/admin/conf/panel.ini file.

    Note: If the [ext-s3-backup] section does not exist, create it.

  3. Add the following lines to the [ext-s3-backup] section:

    [ext-s3-backup]
    request_checksum_calculation = WHEN_REQUIRED
    response_checksum_validation = WHEN_REQUIRED
    RequestChecksumCalculation = WHEN_REQUIRED
    ResponseChecksumValidation = WHEN_REQUIRED

    What are other options/parameters we can use with the S3 Backup extension? Is there a document that details it?

    Thanks!
