As of today, mirrors can only be paused during CDC and not during initial load or query replication. 2. The PostgreSQL source replication slot will still exist and it **will continue to grow** as long the mirror is paused. 3. Pausing a mirror enables you to then add tables to the CDC mirror, along with editing the Sync Interval and Pull Batch Size. ### Why would I pause a mirror ? 1. You could want to run some initial set of validations and analysis on synced data. 2. You could want to [edit the mirror](/features/edit-mirror). ## Pause Mirror Guide The prerequisites for this guide are as follows: 1. You have [a PeerDB setup running](/quickstart/quickstart#deploying-peerdb). 2. You've [kicked off a CDC mirror](/quickstart/quickstart#real-time-cdc) First, select the mirror you created from the Mirrors page: selectmirror Once the mirror is in `Running` state, we can click on the **Pause** button under the **Actions** menu: pausemirror Once clicked, you can refresh the page and see that the **Status** is now **Paused**. To resume, we can click on the **Resume** button under the **Actions** menu: resumemirror Now the **Status** should be back to **Running**.
