If there is archive data in the source bucket, you need to restore the data before migration. To do so, you can perform the following steps:
- Use a tool or the source platform management console to restore the archive data before migration. It is recommended that you configure a long restoration duration.
- If the source bucket is not on Huawei Cloud, follow the restoration methods provided by the source cloud service vendors.
- If the source bucket is on Huawei Cloud, use obsutil to restore the archived data. For details, see Restoring Objects from the Archive Storage.
- On the OMS console, create a migration task for the source bucket again and enable the Archive Data Restoration function. OMS will automatically restore and migrate archive objects that are not restored in advance.
CAUTION:
- If you do not restore archive objects in advance, and if you rely entirely on the automatic restoration function of OMS, it takes 1 to 5 minutes to restore each object, depending on the source object storage services. This can significantly slow down the migration.
- For OBS buckets with direct reading enabled, even though the archived data in these OBS buckets can be directly downloaded without being restored in advance, OMS cannot migrate such data because its storage class is not changed.
- You will be billed for enabling direct reading for your source bucket and enabling OMS to automatically restore archived data in the source bucket. To learn about OBS billing details, see Pricing Details.
- Before you migrate archive data, you are advised to set the storage class of the destination bucket to Standard. After the migration is complete, confirm that the migrated data is correct, and change the storage class of the destination bucket to Archive.
