How much data can I back up by using Hybrid Backup Recovery (HBR)?

You can back up an unlimited amount of data by using HBR. HBR provides backup vaults with unlimited storage space. You can expand backup vaults to store an unlimited amount of backup data.

How long does it take to back up data by using HBR?

The amount of time required to back up data by using HBR varies based on multiple factors such as the total size of data, the total number of files, and the network bandwidth. If the network bandwidth is fixed, the time required to complete a backup job is determined based on the total size of data and the total number of files.

What types of data can I back up by using HBR?

You can use HBR to back up data from your data centers, Elastic Compute Service (ECS) instances including the files, databases, and CSG gateways that are deployed on ECS instances, Apsara File Storage NAS file systems, and Object Storage Service (OSS) buckets. For more information, see What is Hybrid Backup Recovery.

Does HBR encrypt backup data that is stored in the cloud?

Yes, HBR encrypts backup data that is stored in the cloud. The AES-256 encryption method is used to encrypt and protect all backup data in HBR.

Does HBR support data compression and data deduplication?

Yes, HBR supports data compression and data deduplication. The compression ratio and deduplication ratio vary based on the type of source data. The maximum ratio is 30:1.

Does HBR support incremental backup?

Yes, HBR supports incremental backup. During an incremental backup, only the data that is generated after the previous backup is uploaded to HBR. This way, you can back up your data faster and reduce network bandwidth.

What do I do if I forget my logon password for a backup client?

If you forget your logon password for a backup client of an earlier version whose process is hybridbackup, you need to re-download a client from the HBR console and register the client.

How can I create a backup plan?

If you want to use a backup client of an earlier version whose process is hybridbackup, you must create backup policies. When you create a backup plan, you must select the backup source and the required backup policy. After you change a backup policy, the change is synchronized to the associated backup plan. If you delete a backup policy, the related backup job is also deleted. However, the data that is backed up is retained.

Is actual data backed up when I back up symbolic links?

No, actual data is not backed up when you back up symbolic links. Symbolic links of Linux are similar to Windows shortcuts. When you back up symbolic links, the linked data is not backed up.

How can I view the cause of failure of a backup job or a restore job?

If you want to view the cause of a failure, you can move the pointer over the Failed status.
