Restore individual repository from Gitlab backup file

Hi ,

I'm trying to restore only 1 repository from complete gitlab backup file .

I'm using gitlab-rake for backup my repositories .

Backup command : "sudo gitlab-rake gitlab:backup:create"

How i can restore from this tar file only 1 repository ? Or mayber i should change my backup command to backup only specific repository .

more Info :

Gitlab version : GitLab Enterprise Edition 7.13.5-ee

Thanks , Amit
