Restoring Objects from the Archive Storage
Function
You can use this command to restore a specified object whose storage class is cold or restore objects in batches by object name prefix.
- Object content cannot be read during restoration.
- After an object is restored, the time it requires before the object can be downloaded depends on the OBS server.
- obsutil currently does not support the restoration status query. You can use OBS Browser+ or call the API for obtaining object metadata to query the restoration status.
To prolong the validity period of the Archive data restored, you can repeatedly restore the Archive data, but you will be billed for each restore. After a second restore, the validity period of Standard object copies will be prolonged, and you need to pay for storing these copies during the prolonged period.

Examples
- Take the Windows OS as an example. Run the obsutil restore obs://bucket-test/key command to restore a single object whose storage class is cold.
obsutil restore obs://bucket-test/key Start to restore object [key] in the bucket [bucket-test] successfully!
- Take the Windows OS as an example. Run the obsutil restore obs://bucket-test -r -f command to restore objects whose storage class is cold in the bucket in batches.
