Backup and Disaster Recovery Center (BDRC) scores the data protection level of Object Storage Service (OSS) resources in your Alibaba Cloud account. Use the check items and fix methods below to improve protection for your OSS resources.
Check items
| Check item | What it checks | Result | Description |
|---|---|---|---|
| OSS versioning | Whether versioning is enabled for OSS buckets | Passed / Failed | Versioning saves previous versions of objects when they are overwritten or deleted. Restore objects to a previous version if they are overwritten or deleted by mistake. |
| OSS cross-region replication | Whether cross-region replication is enabled for OSS buckets | Passed / Failed | Cross-region replication copies data across regions for cross-region disaster recovery. |
| OSS backup | Whether OSS backup in Cloud Backup is enabled | Passed / Failed | Cloud Backup protects important OSS data with scheduled backup plans. |
| Cross-region replication of OSS backup vaults | Whether cross-region backup is enabled for OSS backup vaults in Cloud Backup | Passed / Failed | After protecting OSS data with Cloud Backup, configure cross-region replication for backup vaults to achieve geo-redundancy. |
Check item details and fix methods
OSS versioning
Description
Checks whether versioning is enabled for OSS buckets. When objects in a versioning-enabled bucket are overwritten or deleted, OSS saves the objects as previous versions. If an object is overwritten or deleted by mistake, restore it to a previous version.
Fix method
Log on to the Object Storage Service console. In the left-side navigation pane, click Buckets. On the Buckets page, find the target bucket and click Enable in the Versioning column.
Versioning is free of charge. However, storage charges apply for both current and all previous versions of objects. To reduce storage costs, delete previous versions that are no longer needed. Downloading or restoring a previous version incurs request and traffic fees. For more information, see Billing overview.
Once versioning is enabled for a bucket, the versioning state cannot be set back to Disabled. The only option is to suspend versioning. For more information, see Overview.
OSS cross-region replication
Description
Checks whether cross-region replication is enabled for OSS buckets.
Fix method
Log on to the Object Storage Service console. In the left-side navigation pane, click Buckets. On the Buckets page, find the target bucket and click the bucket name. In the left-side navigation pane, choose Data Management > CRR or Data Management > SRR.
Cross-region replication (CRR) generates traffic charges when replicating objects. For more information, see CRR overview and Billing overview.
Same-region replication (SRR) does not charge traffic fees. Each object synchronization accumulates the request count, but no request fees are charged. For more information, see SRR overview.
The source and destination buckets must have the same versioning status.
OSS backup
Description
Checks whether the OSS backup feature of Cloud Backup is enabled.
Fix method
Log on to the Cloud Backup console. In the left-side navigation pane, choose Backup > OSS Backup. On the OSS Backup page, click Create Backup Plan. In the Create Backup Plan panel, configure the backup settings as prompted.
Cloud Backup cannot back up or restore symbolic links, object access control lists (ACLs), or objects in buckets of the Archive storage class.
Activate Cloud Backup before using OSS backup. Cloud Backup charges a storage fee for OSS backup. For more information, see Back up OSS objects and Billing methods and billable items. OSS API operations called during backup are charged and included in your OSS bills. For more information, see OSS billable items and billing methods.
Cross-region replication of OSS backup vaults
Description
Checks whether cross-region backup is enabled for OSS backup vaults of Cloud Backup.
Fix method
Log on to the Cloud Backup console. In the left-side navigation pane, click Storage Vaults. On the Storage Vaults page, find the target backup vault and click Cross-Region Backup in the Actions column. In the Create Mirror Vault panel, select the destination region for Region and configure other parameters to complete the cross-region backup configuration.
Activate Cloud Backup before using cross-region backup. Traffic charges apply when copying backup data from the backup vault to the mirror vault. For more information, see Billing methods and billable items.
Cross-region backup does not support archive vaults or backup vaults with Key Management Service (KMS)-based encryption enabled. For more information, see Back up data across regions.
