Data persistence activates the cloud proxy to store data if the connection fails between the cloud proxy and vRealize Operations Cloud. Using data persistence, you can avoid data gaps in case of temporary conectivity issues.

Once the connection is restored, the cloud proxy sends the stored data to vRealize Operations Cloud. The stored data is pushed to cloud before the real-time data. Cloud proxy can store data for a maximum duration of one hour. If there is a lack of space or if the connection fail lasts for more than an hour, the cloud proxy rotates the stored data by deleting the oldest stored data and replacing it with the most recently collected data.

You can activate data persistence when you deploy a new cloud proxy. For more information, see Configuring Cloud Proxies in VMware Cloud. You can also activate data persistence in an existing cloud proxy. For more information, see Monitoring the Health of Cloud Proxies.
