Backup Exec 22 is unable to list the buckets of us-east1 region for Wasabi Cloud Storage. Wasabi Cloud instance is configured using ‘compatible-with-s3-v4’ service provider.

Error Message

New-BECloudRegion : Cannot bind argument to parameter 'Identifier' because it is an empty string.



Wasabi backend is similar to Amazon Web Services S3. For Wasabi, the location constraint is set as blank for all buckets in region us-east-1. While all other regions have Location constraint mapped as the regions, they are created in.

  • Scenario 1 - When no region is set:  In this case, cloud connector checks for “Location is <empty> “. This matches with blank location for the buckets in region “us-east-1” and it lists all the buckets from us-east1 region. Whereas other provider returns storage location error in this case.
  • Scenario 2 - When region “us-east-1” is added then cloud connector checks for the “Location is us-east-1 “. This doesn’t match with location constraint (empty) returned for buckets in region “us-east-1. Due to this, it gives Storage location error instead of listing all buckets in us-east1 region.

Backup Exec does not allow user to add empty region string through BEMCLI command for add new region (New-BECloudRegion) or through generic s3 tool. Even though, empty region is a valid input but BE fails the BEMCLI command with invalid input error. This leads to error and a user will not be able to configure the us-east1 region of Wasabi with BE 22.


Scenario Service host Default region Actual Output Expected Output
1. Configure wasabi cloud instance with compatible-with-s3-v4. Do not configure any region. No region configured for instance. List all the buckets of us-east-1 Storage location error
2. Configure wasabi cloud instance with compatible-with-s3-v4. Add ‘us-east1’ region through BEMCLI. Same as above us-east-1 Storage location error List all the buckets of us-east-1












Workaround for Backup Exec (BE) 22:

Use the attached (modified) cloudprovider.txt (rename to cloudprovider.xml for use)  and CloudConnectorCfg.txt (rename to CloudConnectorCfg.xml for use) file. The CloudProvider.xml contains Wasabi as a service provider and has all its regions added. With the xml in place, user does not need to create any cloud instance/region for Wasabi.

Perform the following steps to configure Wasabi Storage with BE 22. 

  1. Download the 2 attached txt files (rename to .xml as shown CloudProvider.xml and CloudConnectorCfg.xml)
  2. Stop Backup Exec services on the BE server where Wasabi cloud storage need to be configured.

  3. Rename existing CloudProvider.xml and CloudConnectorCfg.xml (present in BE Install Path) and then replace it with the one downloaded from the Technote. 
    Delete Cloudinstance.xml from the server (Note: This Cloudinstance.xml deletion should be done if no private cloud instance configured on the BE server. If another private (not public) cloud instance is already configured please contact Technical support as these attached xmls may need modifications to accomodate the already configured private cloud instance details).
  4. Start Backup Exec services on the Backup Exec server.
  5. In the Backup Exec UI, Go to storage tab and click Configure Cloud Storage.
  6. Enter the name and description that you want to use for this cloud storage device, and then click Next.
  7. Select S3 as the cloud storage provider, and then click Next.
  8. From the Cloud storage drop down select Wasabi.

  1. Click Add/Edit next to the Logon account field
  2. On the Logon Account Selection dialog box, click Add.
    • In the Add Logon Credentials dialog box, do the following:
      • In the Username field, type the Wasabi account access key.
      • In the Password field, type the Wasabi account secret key.
      • In the Confirm password field, type the Wasabi account secret key again.
      • In the Account name field, type a name for this logon account.
      • Click OK twice.
  3. Select the Wasabi logon account that was configured in step 9 & 10, and then click Next.
  4. Select the Wasabi S3 bucket as the logical storage unit that you want to use, and then click Next.
  5. Review the summary, and then click Finish.
  6. Restart BE services. Wasabi cloud storage device should be online now.

Note - The above steps are only required for BE 22.
