Cloud Backup:Which operating systems are supported for ECS disaster recovery?

Last Updated:Sep 23, 2024

This topic describes the Windows and Linux operating systems supported for ECS disaster recovery (CDR) and the corresponding version requirements. CDR is short for continuous data replication.

CDR supports mainstream Windows and Linux operating systems. For more information, see Operating systems.

The following table describes the operating systems that support ECS disaster recovery (CDR).

Important

Only the operating systems listed in the following table are supported. For other operating systems, we recommend that you use the async replication feature.

Operating system

Version

Windows Server

2008 R2, 2012, 2012 R2, and 2016

Linux

Important

You must make sure that the /boot partition and the / partition reside on the same disk. If the partitions do not reside on the same disk, move the partitions to the same disk, and then register the ECS instance for which you want to enable ECS disaster recovery (CDR).

  • Red Hat Enterprise Linux 7.0~7.9

  • Red Hat Enterprise Linux 6.0~6.10

  • CentOS 7.0 to 7.9

  • CentOS 6.0 to 6.10

    Note

    Only 64-bit CentOS is supported.

  • SuSE Linux Enterprise Server 12.0 to 12.3

    Important
    • Only 64-bit SUSE Linux Enterprise Server is supported.

    • If SUSE Linux Enterprise Server 12.1 runs on a VMware virtual machine (VM), a black screen appears after you restart the VM. The black screen is caused by operating system errors, but not by ECS disaster recovery (CDR).

  • Alibaba Cloud Linux 2.1903 LTS 64-bit

    The following kernel versions of Alibaba Cloud Linux 2.1903 LTS 64-bit are supported:

    • 4.19.91-25.1.al7.x86_64
