A website backup is a complete copy of your site’s files and database, stored separately from your main server. If something goes wrong–a hack, a failed update, a server crash–a good backup lets you restore your site to a working state quickly. Most businesses think of backups as optional, something to do someday, but they are one of the cheapest insurance policies a business can buy. The cost of a breach or lost data is thousands of times higher than the cost of proper backups. This guide explains what backups are and how to set them up properly.
What a backup includes
A complete website backup has two parts. The files are your theme, plugins, images, and custom code. The database holds your posts, pages, comments, and configuration. Losing either one breaks your site. A backup must include both, stored somewhere other than your hosting server. If your server catches fire, a backup on the same server burns with it. If your server gets hacked and the backup is on the same server, the hacker can delete the backup too. This is why the golden rule of backups is: keep them off-site, separate from your main server.
Automatic backups are essential
The biggest mistake businesses make is relying on manual backups. “I’ll back up when I remember” is a promise usually broken. Life gets busy, backups get forgotten, and then disaster strikes. Automatic backups run on a schedule–daily or weekly–without you having to think about them. They are also more reliable, since they are not dependent on someone remembering. Most hosting providers offer automatic backups, often included with your plan or for a small monthly fee. Many backup plugins for WordPress automate the process too. The point is to set up a system that runs without you managing it.
How often to back up
For a busy site, daily backups are ideal. For a site that updates a few times a week, weekly is acceptable. The frequency should match how much data you could afford to lose; if losing a week of posts would hurt, back up weekly or more often. Many backup plugins let you set daily, weekly, or custom schedules. After setting up automatic backups, test one to confirm it actually works and can be restored. A backup you cannot restore is worse than no backup.
Where to store backups
Off-site is the rule. Backups stored on your hosting server do not protect you if the server fails. Cloud storage services like Amazon S3, Dropbox, or Google Drive are good choices. Many backup services like WordPress.org host (or plug-ins like BackWPup) automatically upload backups to cloud storage. This separation means a server compromise does not compromise your backups. It also means you can restore even if your hosting provider disappears.
Testing restores
The final step many people skip is testing a restore. A backup that cannot be restored is not a backup; it is a false sense of security. Once you set up backups, restore one to a test environment or a staging server to confirm it works. Practice the restore process so you know what to do if you need it. Most hosting providers and backup tools include restore instructions, but reading them before you need them is much better than learning during a crisis.
Frequently asked questions
How much space do backups take?
A full backup is typically the size of your site. A 1 GB site needs 1 GB per backup. With automatic daily backups, you might keep 30 days, so 30 GB of storage. Cloud storage is cheap, so this is a small cost.
Can I back up my site myself?
You can if you have technical skill to download files via FTP and export your database. But automatic backups are more reliable.
What is the difference between a backup and a restore?
A backup is the copy. A restore is the process of putting the copy back in place when you need it.
How long does a restore take?
Minutes to hours, depending on site size and the cause of the problem. Having a backup means you can restore quickly rather than rebuild from scratch, which would take days.
