Description 1: The data recovery of the snapshot depends on the source data.
If the source data is physically damaged, it cannot be recovered.
In this case, the clone can still recover the source data.
Description 2: After the source data is damaged, LUN copy must make a complete copy of the backup data to restore the source data.
The clone only needs to restore the damaged data, which greatly shortens the recovery time.
-Snapshot: The data recovery of a snapshot depends on the source data. If the source data is physically damaged, it cannot be recovered. In this case, the clone can still recover the source data.
-LUN copy: After the source data is damaged, LUN copy must make a complete copy of the backup data to restore the source data. The clone only needs to restore the damaged data (incremental copy), which greatly reduces the recovery time.
-Remote replication: Remote replication can only protect data between storage devices. The hardware cost is high, and the remote link bandwidth is usually low, and the data recovery time is long. The cloning can realize data protection in the storage device, which can effectively save expenses and shorten the data recovery time.
- A. Description 1 is wrong, description 2 is wrong
