If I delete the data directory, How should I recover?

MongoDB Percona Backup for MongoDB
1

I have a replica set, I made a physical backup, then I stopped the database service and deleted the files in the data directory. I started the data again, initialized the replication set and pbm users, then configured the pbm parameter file and started the agent. But pbm list has no results. I know this information is stored under admin. So how should I restore the database?

Hi, you have to run pbm with --force-resync so that it reads your backups from the storage. After that you will be able to restore.

but, no --force-resync .
