Elastic Desktop Service:Update an image

Image template updates

• An image update task takes approximately 15 minutes.

• Do not share, copy, or modify the image while an update is in progress. Do not use the image to create cloud computers or cloud computer pools during the update. These operations use the outdated image.

Cloud computer image updates

• A cloud computer image update takes approximately 10 to 15 minutes. End users cannot use the cloud computer during the update.

• The system updates only cloud computers that are in the Running state and not connected to any end users.

• If the update fails, the cloud computer may not work as expected. Create snapshots before the update so that data can be restored or the image can be rolled back. For more information, see Use snapshots (public preview).

Automatic push

• The automatic push feature supports only custom images. For system images or shared images, push updates manually.

Scheduled updates

• The scheduled window is 00:00:00 to 05:00:00 daily. This window cannot be changed, but the day is configurable.

• The system imposes a daily limit on the number of cloud computer images updated. If the limit is reached on a given day, select a different day.

• If the current time is less than three hours before 00:00:00 of the following day, the following day cannot be selected.

• If an end user is connected to the cloud computer during the scheduled window, the system does not update the image. Make sure no end users are connected during the scheduled period. For more information, see Configure a scheduled task.

• If a scheduled update task is modified multiple times, the most recent settings take effect.

• After a scheduled update task is created, end users receive notifications about the update time and precautions.

• By default, the system creates snapshots three hours before the scheduled update begins. This can be configured to six hours.

• For multiple scheduled update tasks with the same effective period, the system automatically creates snapshots for all cloud computers involved before execution.
