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 Linux System Disk Image from an External Image File

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 data disk image from an ECS

A data disk image only contains user data. You can create a data disk image from an ECS and then use the image to create new EVS disks. This is a convenient way to migrate data from an ECS to EVS disks.

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 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.

Creating an ECS from a private image

After a system disk image or full-ECS image is created, you can click Apply for Server in the row that contains the image to create an ECS.

Modifying an image

You can modify the following attributes of an image: name, description, minimum memory, maximum memory, and advanced functions such as NIC multi-queue and SR-IOV driver.

Sharing images

You can share an image with other accounts. These accounts can use your shared private image to quickly create ECSs or EVS disks.

Exporting images

You can export private images to your OBS bucket and download them to your local PC for backup.

• Exporting an Image
• Image Export

Encrypting images

You can create encrypted images to improve data security. KMS envelope encryption is used.

Encrypted images can be created from external image files or encrypted ECSs.

Replicating images within a region

By replicating images within a region, you can convert encrypted and unencrypted images into each other or enable some advanced features, for example, fast instance provisioning.

Replicating Images Within a Region

Tagging an image

You can tag your private images for easy management and search.

Exporting image list

You can export the public or private image list in a given region as a CSV file for local maintenance and query.

Deleting images

You can delete images that will be no longer used. Deleting an image does not affect the ECSs created from that image.
