-Redis saves snapshots of the database every few minutes. You can find them in the corresponding folder (for example, `\data\dump.rdb`). Use the `sudo docker cp <container_id>:/data/dump.rdb /tmp` to obtain the snapshot from the container (in this case, the copied data is stored in `/tmp/snap-private-tmp/snap.docker/tmp`).

+## Why I am facing authorization error when fetching data from hosted redis server?
+
+When utilizing the database in python code (as introduced in [here](https://github.com/sotopia-lab/sotopia/blob/main/notebooks/redis_stats.ipynb)), make sure you use in the command line:
+
+```sh
+export REDIS_OM_URL="redis://:QzmCUD3C3RdsR@localhost:6379"
+```
+
+If you plan to add environmental variables in the python code like this:
+
+```sh
+os.environ['REDIS_OM_URL'] = "redis://:QzmCUD3C3RdsR@localhost:6379"
+```
+
+We need to make sure this line of code is put before `import redis` to make sure that you will not face additional authorization error.
