FAQ about OSS backup

What do I do if an OSS backup fails with the error "Failed to access the OSS Bucket. Access to the OSS Bucket is restricted by the access policy"?

• Issue

  An OSS backup fails, and the following error message is returned: "Failed to access the OSS Bucket. Access to the OSS Bucket is restricted by the access policy. Check the OSS Bucket access policy and VPC configuration to ensure that Cloud Backup has permissions to access the OSS Bucket to be backed up."

  

• Cause

  Cloud Backup does not have the required permissions to access the OSS Bucket because of restrictions in the bucket policy.

• Solution

  1. Log on to the OSS console.

  2. Find the target OSS bucket and click Authorize on the Bucket Policy tab.

     

     1. Authorized User: Select All Accounts, RAM User, or Other Accounts. For more information, see Authorize access to OSS using a bucket policy.

     2. For Authorized Operation, select Advanced Settings.

     3. For Effect, select Allow.

     4. Actions: The permissions required by Cloud Backup to perform operations on the OSS bucket. For more information, see Service-linked Role.

3. In the Create Restore Job panel, complete the following steps.

   1. Select the backup vault that contains the target backup data.

   2. Select the bucket to which the backup data belongs.
