How to back up your forum (and actually restore it)

Every forum owner eventually needs a backup: after a bad update, a hacked account, a hosting problem, or a mass spam cleanup gone wrong. A backup you've never restored is only a hope. Here's a simple routine.

What to back up

• The database. Posts, members, private messages and settings live here. For MySQL/MariaDB-based forums (phpBB, SMF, MyBB, XenForo, vBulletin), this is a SQL dump.
• The files. Uploaded attachments, avatars, custom themes or styles, extensions and the config file. Attachments are often the biggest part and the easiest to forget.

How to make the backup

• Hosting control panel: cPanel and similar panels can download a full account backup, or a backup of one database.
• Command line: mysqldump creates a SQL file of the database. Then compress the forum's directory with tar or zip.
• Built-in tools: some packages include backup features, and their documentation explains how (see the phpBB Knowledge Base for phpBB). Discourse has built-in backups that can be scheduled and stored offsite (see Discourse Meta).

How often

Match it to how much you can afford to lose. A busy forum should back up the database daily. A quiet one might do it weekly. Always take a fresh backup right before upgrades, extension installs or bulk deletes.

Store copies offsite

Keep at least one copy somewhere other than your web host, such as cloud storage or your own computer. If the hosting account is lost, backups stored on it are lost too. Keep several dated copies, not just the latest.

Test a restore

A few times a year, restore a backup to a test subdomain or a local install. Check that you can log in, that recent posts are there, and that attachments load.

Protect the backup files

Backups contain member emails and password hashes. Never leave them in a public web folder, and limit who can download them.
