hi @Ilan_Manouach !!
Depending on how you deployed Verba, your data should be stored in a docker volume or on the Weaviate embedded volume path.
One way to make sure you have a backup, is to migrate that data to a new cluster, and point the new Verba there.
Here is a migration guide that can get you there:
When you start Verba, there should be some info with hints on where your data should be stored.
Let me know if this helps.
Thanks!
