Restore metabase with mv.db file

I accidently pruned on my EC2 instance and it removed all my data from metabase. I'm trying to recover it with an old copy of backup which is the metabase.db.mv file. Can you please guide me how can I do that ?
I'm new to this and have messed up all my data due to this.

I am not sure what you can do but for reference if you decide to redeploy metabase. just move away from H2

I'd be happy to help. I'll contact you by direct message, if you send me the metabase database files, I'll take a quick look. Then we can decide on a fixed price to repair/move to Postgres.
