Data retention and cleanup schedules vary by table type. Core tables such as Incident, Change, and Problem retain records indefinitely unless administrators configure cleanup rules. System tables with transactional data rotate automatically on predefined schedules.

Records remain within the instance until removed by users or admins, either individually or in bulk through an integration or scheduled job. Some tables are configured to remove data by default on a weekly or monthly basis through table rotation. Tables using table rotation hold only a subset of transient data over time before rotating away on a predefined schedule. Records that rotate away are deleted from the instance. System data rotation schedules: System transactional data (syslog): Maintains a rolling 8 weeks of dataSystem events (sysevent): Deletes data daily, maintaining a rolling 1 week of data Table rotation removes data based on a defined rotation schedule. A related feature called table extension retains data and automatically extends data into new, smaller table shards to improve performance. To view table rotations and extensions: Go to System Definition > Table Rotations. (https://__INSTANCE__.service-now.com/sys_table_rotation_list.do) Important: Modifications to table extension and rotation can affect instance performance. Contact ServiceNow before making changes. For more information see Table rotation. Table Cleaner Removal You can remove data from your instance by deleting records individually or in bulk using a filtered list. ServiceNow provides a Table Cleaner job that runs by default and removes records from specific tables by matching filter criteria to predefined rules. Instance admins can create custom Table Cleaner rules to remove records from any table after a specified period (30, 60, 90+ days) based on user-defined criteria. To view and configure Table Cleaner rules: Go to System Maintenance > Table Cleanup. (https://__INSTANCE__.service-now.com/sys_auto_flush_list.do) For more information, see Table cleaner. Instance Size To check how much data your instance retains, go to Instance Usage > Application Usage Overview. (https://__INSTANCE__.service-now.com/home.do?sysparm_view=usage_overview) On this page, locate Primary DB Size (MB), which displays the primary database size of your instance in megabytes. Divide by 1,000 to get the value in GBDivide by 1,000,000 to get the value in TB You can also request database size information through the Database Footprint Service Catalog item in Now Support, which returns the total database size and top 10 tables by size. For additional data usage information (total, per table, and so on), contact ServiceNow Customer Support. Service Catalog for Instance Storage Usage ServiceNow provides an automated workflow that allows you to request a list of production and non-production instances in your account along with storage consumption for each instance. To request an instance storage report: Go to Now Support.Select Automation Store.Select Service Catalog in the left navigation.In the Search bar, enter Cloud and locate Cloud usage request.Select Request.
