 #### Using Selective Sync
 
-Use Selective Sync to manage the data you send to your warehouses by choosing which tables and columns (also known as properties) to sync. Syncing fewer tables and properties will lead to faster and more frequent syncs, faster queries, and using less disk space.
+Selective Sync lets you choose which tables and columns (also called properties) to sync. Syncing fewer tables and properties reduces sync times, improves query performance, and uses less disk space.
 
 You can access Selective Sync in two ways:
-- From the Set Selective Sync page as you connect your warehouse to Profiles Sync.
-- From the Profiles Sync settings (**Profiles Sync** > **Settings** > **Selective sync**).
+- From the Set Selective Sync page when you connect your warehouse to Profiles Sync.
+- From Profiles Sync settings (**Profiles Sync** > **Settings** > **Selective Sync**).
 
-You'll see a list of event type tables, event tables, and [tables Segment materializes](/docs/unify/profiles-sync/tables/#tables-segment-materializes) available to sync. Select the tables and properties that you'd like to sync, and be sure the ones you'd like to prevent from syncing aren't selected.

-Regardless of schema size, only the first 5,000 collections and 5,000 properties per collection can be managed using your Segment space. To edit Selective Sync settings for any collection which exceeds this limit, [contact Segment support](https://app.segment.com/workspaces?contact=1){:target="blank"}.

 #### When to use Selective Sync
 
-Use Selective Sync when you want to prevent specific tables and properties from syncing to your warehouse. Segment stops syncing from disabled tables or properties, but will not delete any historical data from your warehouse.
+Use Selective Sync to prevent specific tables and properties from syncing to your warehouse. Segment stops syncing from tables or properties you turn off, but it doesn’t delete historical data from your warehouse.
 
-If you choose to re-enable a table or property to sync again, only new data generated will sync to your warehouse. Segment doesn't backfill data that was omitted with Selective Sync.
+If you turn a table or property back on, only new data will sync. Segment doesn’t backfill data that was omitted with Selective Sync.
 
 #### Using historical backfill
 
-Profiles Sync sends profiles to your warehouse hourly once setup completes. Setup is complete after an initial automated backfill syncs all profile data. To initiate the backfill, the Profiles Sync requires live data flowing into your workspace. If live data isn’t available, you can send test data to trigger the backfill sooner. Backfill can also sync historical profiles to your warehouse.

-- Profile raw and materialized tables sync your entire historical data to your warehouse.
-- Profiles Sync gathers the last two months of all events for Event type and Track event tables and syncs them to your warehouse.
