If you want to temporarily stop writing data to a destination database, you can pause and retain your Data Transmission Service (DTS) instance. This way, you can restart the DTS instance when you need to resume writing data to the destination database.
Prerequisites
A data synchronization or migration instance is created. For more information, see Overview of data synchronization scenarios and Overview of data migration scenarios.
NoteA serverless instance is a special synchronization instance that can be paused.
The Status of the instance is Running.
Usage notes
Data inconsistency may occur if you pause a DTS instance.
If a paused DTS instance fails to run or is forcibly terminated, the incremental data loss may occur.
You cannot resume DTS instances that have been paused for more than seven days, including serverless instances.
A paused serverless instance still consumes 1 DU of resources and incurs costs.
If your DTS instance does not migrate incremental data or your DTS instance transfers a small amount of data, you may fail to pause the DTS instance.
You are still charged for a data synchronization instance during the period in which the instance is passed, regardless of whether the source or destination database can be connected.
You can not pause a change tracking instance. You can release DTS instances based on your business requirements. For more information, see Release DTS instances.
If you no longer use a subscription task that auto-renewal is enabled, we recommend that you manually disable the auto-renewal or release the instance to which the task belongs. Otherwise, you will be charged additional fees. For more information, see Renewal guide and Release DTS instances.
Procedure
This example shows how to pause one or more data synchronization instances.
Use one of the following methods to go to the Data Synchronization page and select the region in which the data synchronization instance resides.
DTS console
Log on to the DTS console.
In the left-side navigation pane, click Data Synchronization.
In the upper-left corner of the page, select the region in which the data synchronization instance resides.
DMS console
NoteThe actual operations may vary based on the mode and layout of the DMS console. For more information, see Simple mode and Customize the layout and style of the DMS console.
Log on to the DMS console.
In the top navigation bar, move the pointer over Data + AI and choose .
From the drop-down list to the right of Data Synchronization Tasks, select the region in which the data synchronization instance resides.
Pause one or more data synchronization instances.
Pause one data synchronization instance
On the Data Synchronization page, find the data synchronization instance that you want to pause and choose
> Pause Task in the Actions column. Pause multiple data synchronization instances at a time
On the Data Synchronization page, select multiple data synchronization instances that you want to pause and click Pause Task in the lower part of the page.
In the message that appears, click OK.

FAQ
What is the status of a DTS instance after it is paused?
After a DTS instance is paused, the Status of the DTS instance changes to Paused.
Can I resume a paused DTS instance?
In most cases, a DTS instance that is paused for no more than 24 hours can be resumed. If a DTS instance transfers a small amount of data and is paused for no more than seven days, the DTS instance can be resumed. We recommend that you do not pause a DTS instance for more than six hours.
