I am backing postgre SQL db using pgadmin.
However, while the db has a password the backup file has no protection. The backup file can be taken and restored to any blank database without any password !!
How do I make the backup secure / password protected? Thanks.
PostgreSQL and PgAdmin have no built-in facility for backup encryption and password protection.
There are numerous ways you can encrypt backups. You can use gnupg, but I suspect you will be happier using a zip utility that supports encryption. I recommend 7zip, which supports the zip64 format and zip file encryption.
