Restoring a File or Folder

Restore Archive objects before downloading them.

To extend the validity period of the restored Archive data, you can repeatedly restore the Archive data, but you will be billed for each restore. After a second restore, the validity period of the Standard object copies will be extended. You need to pay for storing these copies during the extended period.

Context

Archive storage is secure, durable, and inexpensive for storing data that is rarely accessed (once a year on average). It is suitable for data archiving and long-term backup. This storage class allows you to safely store your data at low cost. However, it may take hours to restore data stored in this class.

If an Archive object is being restored, you cannot suspend or delete the restore task.

Objects in the Restoring state cannot be restored again.

Procedure

  1. Log in to OBS Browser+.
  2. Go to the object list in the target bucket.
  3. Select the file or folder you want to restore and choose More > Restore Object. The window shown in Figure 1 is displayed.

    To restore an object, you must configure the validity period and restore speed. Table 1 describes relevant parameters.

    Table 1 Restoring an object

    Parameter

    Description

    Object Name

    Name of the object or path to be restored.

    Validity Period

    Time duration when an object remains in the Restored state after it has been restored. The validity period starts when the object is restored. You can set the validity period to an integer ranging from 1 to 30 (days). The default value is 30.

    For example, you set Validity Period to 20 when restoring an object. 20 days after the object is restored, its status will change from Restored to Unrestored.

    Speed

    How fast an object will be restored.

    • Expedited: All Archive data can be restored within 1 to 5 minutes.
    • Standard: All Archive data can be restored within 3 to 5 hours.

  4. Click OK to confirm the restored file or folder.

    To view the restoration status of the file or folder, click next to the object and choose Object Properties to view the restoration status. You can download the file only after it has been restored.

Follow-Up Procedure

Within the validity period of a restored object, you can restore the object again. Each time the object is restored, its validity period will restart. This extends the validity period.

1. If a restored object is restored again, its expiration time should be later than the time set for the previous restoration. For example, if an object is scheduled to expire at 4/12/2021 08:00:00 GMT+08:00 after it is restored for the first time, it should expire later than 4/12/2021 08:00:00 GMT+08:00 after the second restore.

2. You are advised not to restore a large number of files in one batch. When more than 10,000 objects are being restored, OBS Browser+ will take a long time to query the restoration progress of such objects. If you indeed need to restore such a large number of files in one batch, you are advised to use SDKs or APIs to query the restoration progress. You can also download files after the maximum restoration time, which is estimated based on the restoration rate you selected.
