Backup and restore SQL Server database with encrypted columns: what should I backup along with database?

Assume I've backed up a SQL Server database with Management Studio, and that database have some encrypted columns. Now I want to restore this database into another fresh-enrolled MSSQL server. To use encrypted columns I had to: 1. Create database master key; 2. Create certificate; 3. Create symmetric key. Which of those are stored along with backup, and which I should backup manually and restore on the other server manually as well? I see there is SQL statements backup master key, restore master key, backup certificate, create certificate ... from file. So, along with database itself, there are: 1. Master key; 2. Master key password; 3. Certificate; 4. Certificate private key; 5. Symmetric key. So what (and how) should I deal with when I restore my database on a fresh server? Thank you!
