Creating a system disk image from an ECS or BMS

After creating a cloud server, you can set it up, installing whatever software or application environment you need, and then use the preconfigured server to create a system disk image. You can create new cloud servers with the custom configurations from the image, which frees you from a lot of repetitive work.

Creating a system disk image from an external image file

You can import a system disk from your local PC or other cloud platforms, and use the imported image to create new cloud servers or reinstall or change the OSs of existing cloud servers.

Creating a system disk image from an ISO file

In contrast with other image formats, an ISO file can be used only after it is decompressed using a tool, such as UltraISO or VirtualBox. For details about the image creation process, see the Helpful Link column in the table.

Creating a system disk image using Packer

Packer is an open-source tool used to create custom images. It simplifies private image creation by using manageable code. In this way, you can customize images easily.

Creating a data disk image from an external image file

You can import the data disk image of a local server or a server on another cloud platform to Huawei Cloud and then the image can be used to create EVS disks.

Creating a full-ECS image from an ECS, a CSBS backup, or a CBR backup

You can use an ECS with data disks to create a full-ECS image, complete with an OS, various applications, and your service data. The full-ECS image then can be used to quickly provision identical ECSs for data migration.

A full-ECS image can be created from an ECS, a CSBS backup, or a CBR backup.
