Hi, @Harinishree,

If you use the ./startFabric script directly to run the network. It first kills the existing network before starting a new one. you can modify the script to make sure it just stops the nodes instead of deleting them. Also, you can take a backup from the volumes before you stop the network.

For in detail information on Hyperledger fabric back up and restore you can go through this https://medium.com/@jariarud/hyperledger-fabric-backup-and-restore-3263561e259e

Hey, @Harinishree,

You can also do one thing, bind volumes to your host machine. So that when you restart your peer service again it doesn't lose all the data.
