Hi @Truong_Ha  
Welcome to the community!  
Regarding taking backup of one database, you can choose selective backup. Please go through the tab [selective backup](https://docs.percona.com/percona-backup-mongodb/usage/start-backup.html#__tabbed_1_3) and specify the desired namespace. Also, before going to implement the selective backup, make sure to read the [limitation](https://docs.percona.com/percona-backup-mongodb/features/selective-backup.html#known-limitations-of-selective-backups-and-restores) of it as well.

Thanks,  
Mukesh
