What is Cloud Backup

Prerequisites

Before you read this topic, you should understand the following concepts:

• What is a data center?

• What is cloud storage?

• What is data backup?

• What is object storage?

Scenarios

• Back up data on the cloud

  Back up important data to a backup vault over the Alibaba Cloud internal network. Supported data sources include ECS files, self-managed MySQL, Oracle, SQL Server, and SAP HANA databases, NAS file systems, OSS buckets, and Tablestore instances. Cloud Backup supports real-time backups of MySQL and Oracle databases with a near-zero recovery point objective (RPO). Back up data from other cloud platforms to a backup vault on Alibaba Cloud.

• Back up on-premises data to the cloud

  Back up on-premises data from servers, NAS file systems, VMware virtual machines, and databases directly to a backup vault with flexible backup policies.

• Cross-region or cross-account backup and ECS cross-region disaster recovery

  • Implement cross-region or cross-account disaster recovery for your backup data using cross-region backup or cross-account replication of backup vaults. Use cross-account backup to add multiple layers of data protection.

  • Cloud Backup provides two types of cross-region disaster recovery solutions for ECS instances to meet different RPO and RTO requirements: continuous replication and async replication of cloud disks.

• Migrate VMware VMs to the cloud

  Migrate on-premises VMware virtual machines to the cloud without an agent. Cloud Backup provides a simple and fast incremental migration method.

• Archive data from on-premises NAS, HDFS, and S3-compatible storage based on policies

  Archive large volumes of files from on-premises NAS, Hadoop Distributed File System (HDFS), and S3-compatible storage to an archive vault or a cold archive vault based on policies. Configure flexible archive policies. Cloud Backup also supports full-text search of file content in both local storage and archive vaults, with results returned in seconds.
