BDRC data high availability overview - Backup and Disaster Recovery Center

The Overview of Data High Availability page in Backup and Disaster Recovery Center (BDRC) shows the storage redundancy status of your OSS buckets and Tablestore instances. The Overview of Data High Availability page displays resource counts by redundancy type and lets you convert OSS buckets from locally redundant storage (LRS) to zone-redundant storage (ZRS). The following sections describe the Overview of Data High Availability in Backup and Disaster Recovery Center.

Supported scope and limitations

Tablestore does not support storage redundancy conversion. Zone-redundant storage covers Tablestore redundancy options.
OSS bucket storage redundancy can only convert from LRS to ZRS. This conversion is irreversible and switches billing to ZRS rates. Storage fees.
Regional availability for this conversion is listed in Convert the storage redundancy type of a bucket.

Note

The high availability status is informational only and does not affect the data protection score in the Resource Risk overview.

Data high availability

Displays OSS bucket counts by storage class and redundancy type. Data refreshes daily; click Check All Resources for a manual update. Click the locally redundant storage count to view those buckets in Resource Center.

A page-level warning states: if the zone hosting your LRS data becomes unavailable, that data is inaccessible. Use zone-redundant storage for higher availability.
Displays Tablestore instance counts by specification and redundancy type. Data refreshes daily; click Check All Resources for a manual update. Click the locally redundant storage count to view those instances in Resource Center.

Data disaster recovery screen

On the Data Disaster Recovery Screen page, yellow indicates locally redundant resources and white indicates zone-redundant resources.

Click an OSS bucket to view its data protection risks and high availability status. Click Convert to Zone-Redundant Storage to open the bucket in Resource Center and convert from LRS to ZRS.
Click a Tablestore instance to view its data protection risks and high availability status.

A details card shows the data protection risk score and star rating. The high availability status section displays the redundancy type (for example, locally redundant storage). Click Fix to address the risk.

Resource list page

The OSS list shows all resources by default. Filter by storage redundancy type at the top. High availability status refreshes daily; click Check Resource to update manually. You can convert OSS bucket redundancy directly in the BDRC console:
1. Click Convert Now to start the LRS-to-ZRS conversion.
2. Click Confirm Conversion, then click OK to start the conversion task.
  
  The Convert Locally Redundant Storage to Zone-Redundant Storage panel notes the following constraints: conversion is LRS-to-ZRS only, irreversible, and takes approximately one day. Archive and Deep Cold Archive files remain LRS. The task cannot be canceled. Cross-region replication is restricted during conversion. A deleted bucket's name cannot be reused for seven days.
  
  A confirmation dialog reminds you that billing switches to ZRS rates and that the conversion is irreversible.
3. After confirmation, track progress in the high availability status column. Click View Task Details and check the Conversion Task Status.
  
  Note
  A bucket converted within the last 24 hours may still appear as LRS because BDRC refreshes daily. Click Check Resource to refresh manually.
The Tablestore list shows all resources by default. Filter by storage redundancy type at the top. The high availability status refreshes daily; click Check Resource to update manually.

When filtered by locally redundant storage, the list shows Instance ID/Name, Instance Specification, Instance Status, Creation Time, Region, Data Protection Score, Resource Checks, and Risk Items. Click Details in the Actions column to view instance details.
