A reference topic that includes general guidelines to optimize your clone duration when requesting a clone.

Configuring additional settings for your clone request can significantly increase your clone completion time.

When creating a clone request, consider the following guidelines.

Set the amount of data copied from the task table to Full. This option clones all data from the task table and its child tables to the target instance.

Note: The Last 90 days option can increase duration, as it takes longer to remove records from the task table that are older than 90 days after restoration.
Selecting Exclude Attachment Data on the clone request form can add to your clone duration.
Don't preserve large amounts of data in your request. If you must preserve table data, such as users, groups, and roles, consider exporting the records to a file and importing them after cloning.
Add conditions to the preservers configured for the clone request to only preserve the data that you need.
Use clone chaining to split up your request, see Clone terminology.

# General guidelines for optimizing your clone duration

A reference topic that includes general guidelines to optimize your clone duration when requesting a clone.

Configuring additional settings for your clone request can significantly increase your clone completion time.

When creating a clone request, consider the following guidelines.

- Set the amount of data copied from the task table to `Full`. This option clones all data from the task table and its child tables to the target instance.

**Note:** The `Last 90 days` option can increase duration, as it takes longer to remove records from the task table that are older than 90 days after restoration.

- Selecting Exclude Attachment Data on the clone request form can add to your clone duration.
- Don't preserve large amounts of data in your request. If you must preserve table data, such as users, groups, and roles, consider exporting the records to a file and importing them after cloning.
- Add conditions to the preservers configured for the clone request to only preserve the data that you need.
- Use clone chaining to split up your request, see [Clone terminology](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-administration/clone-terminology.md).
