How to restore repository in nexus3

How to restore repository in nexus3 which is deleted mistakenly while running pipeline.
I am unable to find .properties file of particular repo as there are multiple directory like vol-01 to vol-02 and inside it chap-01 and etc.

@neha.shrivastava, repositories are defined by configuration that lives in the embedded database. The vol-01/chap-01 files are just the stored binaries, not any configuration.

To recover a deleted repository, you’ll need to restore from a backup of the database.

(Make sure to stop nexus and/or the compact blob store task, otherwise the binaries themselves will be deleted.)
