+# Database snapshot guide
+
+For this guide we will be taking a snapshot of a parachain and relay chain. Please note we are using a local chain here `rococo_local_testnet` and `local_testnet`. Live chains will have different values
+
+*Please ensure that the database is not in current use, i.e no nodes are writing to it*
+
+# How to prepare database for a relaychain
+To prepare snapshot for a relay chain we need to copy the database. 
+
+```
+mkdir -p relaychain-snapshot/alice/data/chains/rococo_local_testnet/db/
+
+cp -r chain-data/alice/data/chains/rococo_local_testnet/db/. relaychain-snapshot/alice/data/chains/rococo_local_testnet/db/ 
+
+tar -C relaychain-snapshot/alice/ -czf relaychain.tgz data
+```
+# How to prepare database for a parachain
+
+To prepare snapshot for a parachain we need to copy the database for both the collator node (parachain data) and validator (relay data)
+
+```
+#Parachain data
+mkdir -p parachain-snapshot/charlie/data/chains/local_testnet/db/
+
+# Relay data
+mkdir -p parachain-snapshot/charlie/relay-data/chains/rococo_local_testnet/db/
+
+cp -r chain-data/charlie/data/chains/local_testnet/db/. parachain-snapshot/charlie/data/chains/local_testnet/db/

+
+tar -C parachain-snapshot/charlie/ -czf parachain.tgz data relay-data
+```
+
+# Restoring a snapshot
+Zombienet will automatically download the `*.tgz` file to the respective folder for a run. However you can also download it manually, just ensure you extract the tar file in the correct directory, i.e. the root directory
+`chain-data/charlie/`
