To roll back data from a cloud disk snapshot, you typically need to follow these steps:
- Identify the Snapshot: Locate the specific snapshot you want to use for the rollback. Ensure it contains the desired data state.
- Stop Disk Operations (if required): Some cloud platforms require you to detach or stop the disk before restoring from a snapshot to avoid data corruption.
- Restore from Snapshot: Use the cloud provider’s console or API to initiate the rollback process. This usually involves creating a new disk from the snapshot or overwriting the existing disk.
- Reattach or Restart: If the disk was detached, reattach it to your instance. If the instance was stopped, restart it to apply the changes.
Example:
Suppose you have a cloud disk snapshot taken on January 1st, and you want to revert to that state due to accidental file deletions. You would:
- Select the January 1st snapshot in the cloud console.
- Create a new disk from the snapshot (or overwrite the current disk if supported).
- Detach the current disk from your instance, attach the restored disk, and restart the instance.
Tencent Cloud Service Recommendation:
For Tencent Cloud, you can use Cloud Block Storage (CBS) Snapshots to roll back data. Navigate to the CBS console, select the target snapshot, and choose "Create Disk" to restore data to a new disk or "Rollback Disk" to restore directly to the original disk (if supported). Ensure proper backup before proceeding.
