Response codes#

Cloud Backup returns an HTTP code that denotes the type of response.

Successful response codes are returned only if all configured providers were successful in processing the request.
When an error occurs, the Rackspace Cloud Backup Service returns a fault object containing an HTTP error response code that denotes the type of error. In the body of the response, the system returns additional information about the fault.

The following table lists possible responses with their associated codes and descriptions.

Table: Response codes for Cloud Backup

Response	Associated response code	Description
OK	200	The request has succeeded.
Created	201	The request has been fulfilled and a resource was created.
Accepted	202	The request has been accepted for processing.
No Content	204	The request has been fulfilled but does not return a representation (that is, the response is empty).
Bad Request	400	There was one or more errors in the user request.
Unauthorized	401	The supplied token is not authorized to access the resources, either it’s expired or invalid.
Forbidden	403	Access to the requested resource was denied.
Not Found	404	A requested resource was not found.
Instance Fault	500	This is a generic server error and the message contains the reason for the error. This error could wrap several error messages and is a catch all.
Not Implemented	501	The requested method or resource is not implemented.
Service Unavailable	503	The Rackspace Cloud Backup Service is not

The symptoms and solutions for some frequently encountered issues follow.

Backups get corrupted

Does your server have a backup agent and did you clone it to create a new backup system? This means that two backup agents exist with the same credentials writing to the same vault.
Solution: Ensure the agent on the cloned backup server is re-registered before any backups are run.

Backups get network error

Solution: Make sure that your backup server has a connection to both service net and public net. If it is on an isolated network, the backup agent is able to function properly.

Backups sometimes fail

This is most commonly caused by either a failure to communicate with Cloud Files, running out of disk space, or a failure to communicate with Cloud Backup.
Sometimes the agent might fail to backup a particular file because of a permissions error. Either the file is in use when the agent attempts to save it or the file in question cannot be read by the agent. Consider permissions when hunting for the root cause of a backup failure.
Solution: Make sure that you’re running the latest agent release. After that, attempt to determine the cause of the error, and try the backup or restore again if it is an intermittent error.

Backup or Restore is slow

If your backup or restore is encrypted, it can be especially slow. Encryption comes at a cost.
If your system uses Cloud Block Storage as the storage medium, this is known to introduce some slowdowns. Consider whether the benefits of using Cloud Block Storage outweigh the need for faster backups/restores.
Solution: Make sure that you’re running the latest agent release. After that, attempt to determine the cause of the error, and try the backup or restore again if it is an intermittent error. We’re always working on making backup more robust.
