Backup Storage Operations

You can perform the following operations on a backup storage:
  • Search: Support three types of search method on the backup storage page: name, UUID, and advanced.
  • Add backup storage: Add the backup storage to the cloud. Each backup storage has its own corresponding backup storage type. When you select different backup storage types, the Add Backup Storage page is a bit different. This chapter will introduce all these differences according to the types.
  • Enable: Enable the backup storage that is in the disabled state. Batch operations are supported.
  • Disable: Disable the backup storage. Batch operations are supported.
  • Reconnect: Reconnect the backup storage. When you reconnect the backup storage, the storage information that is associated with the backup storage will be updated. Batch operations are supported.
    Note:
    • When a backup storage reconnects, you cannot manage and operate resources on the backup storage.
    • If any host can connect normally to the backup storage, the status of the backup storage will be Connected.
  • Clear data: Clear both the invalid data that have been completely deleted and the temporary data that were expired on the backup storage to release storage spaces.
    Note:
    • For example, assume that you have deleted an image file totally, and have deleted VM instances that you created by using this image file. If you clear data, storage spaces of the backup storage will be released. After you clear the data successfully, the UI page will display the released space size and the available space.
    • Only ImageStore backup storages support the preceding operation.
    • When you clear data, avoid related operations of writing data.
  • Delete: Delete the backup storage. Batch operations are supported.
    Note:
    • Exercise caution. If you delete the backup storage, all image files on the backup storage will be deleted as well.
    • The preceding deleting operation can only remove the records of the backup storage and the image on the ZStack. Real data will not be deleted.
  • Clear data: Click OK to clean up original data reserved during the migrations across Ceph primary storages on the Clear Data tab of the Ceph backup storage details page. Exercise caution. After you clean up the original data successfully, the data cannot be recovered.
