1. What Is a Website Backup?

A website backup is a separate copy of the files, data, and other components needed to rebuild or restore a website.

Depending on the platform, a complete website backup may include:

• Website files
• Images and uploaded media
• The website database
• Theme files
• Plugins or extensions
• Configuration files
• Custom code
• Other website-specific data

NIST describes a backup file as a copy of files and programs created to support recovery after data loss or another disruption. Its guidance on protecting data from ransomware and data loss also emphasizes planning, maintaining, and testing backups rather than simply creating them.

2. Why Businesses Need Website Backup and Recovery

Websites can fail for reasons that have nothing to do with a business doing something wrong.

A backup may be needed after:

• A plugin or software update causes an error
• Website files are accidentally deleted
• A database becomes corrupted
• A security incident changes or removes files
• A server or hosting problem affects the website
• A website migration goes wrong
• Custom code causes unexpected issues
• A page or configuration needs to be restored to an earlier version

Without a usable restore point, rebuilding damaged or missing website content can take far longer than restoring a known-good backup.

This is also why reliable website hosting and management should include clear backup and recovery planning rather than treating backups as an afterthought.

3. A Backup Should Include Both Website Files and the Database

Many websites rely on both stored files and a database.

Website files may contain themes, plugins, scripts, images, and configuration files. The database may contain pages, posts, settings, user information, form data, product information, and other dynamic content.

Backing up only one side can leave a business with an incomplete restore.

A business using WordPress, for example, may restore the site's files successfully but still be missing recent content if the database backup is outdated.

A complete website backup strategy should account for every component required to rebuild the working site.

4. How Often Should Website Backups Run?

There is no single backup schedule that fits every website.

The right frequency depends on how often information changes and how much recent data the business can reasonably afford to lose.

A mostly static website may change only a few times per month. An ecommerce site, membership website, active blog, or website receiving customer submissions may change throughout the day.

NIST's small-business security guidance notes that backup frequency should reflect how much information changes and the potential impact of losing that information. Some environments may need weekly backups, while others may require daily or more frequent copies.

5. Backups Should Not Exist Only on the Live Website Server

Keeping every backup in the same location as the production website creates a single point of failure.

If the server fails, an account is compromised, or malicious software gains access to the same storage, the website and its backups could both be affected.

CISA's StopRansomware guidance recommends keeping offline, encrypted backups of critical data and regularly testing their availability and integrity.

Businesses should understand whether their website backups are stored separately from the live environment and whether additional protections prevent them from being modified or deleted.

6. What Is Backup Retention?

Backup retention refers to how long backup copies remain available before they are removed or replaced.

A service may keep several restore points, such as copies from the last few days or weeks.

Having multiple restore points can be useful because a problem may not be discovered immediately.

If malicious code was added five days ago but the business notices it today, restoring only yesterday's backup may bring the same problem back.

Retention planning should give the business enough historical options to choose a clean and appropriate recovery point.

7. Full Backups and Incremental Backups Are Different

Backup systems may use different methods depending on storage, performance, and recovery needs.

A full backup creates a complete copy of the selected website data.

An incremental backup generally saves data that has changed since a previous backup, reducing the amount of information that needs to be copied each time.

Some systems use a combination of full and incremental backups.

Businesses do not necessarily need to manage these technical details themselves, but they should understand whether the backup system can provide a complete and reliable restoration when needed.

8. Automated Website Backups Reduce Dependence on Memory

Manual backups can be useful before major website changes, but they are easy to forget.

Automated website backups can run on a schedule without relying on someone remembering to create a copy every day or week.

Automation is especially useful for business websites that change regularly.

It does not remove the need for monitoring. Someone should still confirm that backups are completing successfully and that storage limits, failed jobs, or account issues are not preventing new backups from being created.

9. A Successful Backup Is Not the Same as a Successful Restore

A backup system may report that a job completed successfully, but that alone does not prove the website can be recovered.

Files may be incomplete, a database may fail to import, credentials may be unavailable, or the backup may depend on systems that are no longer accessible.

NIST's backup guidance emphasizes testing backups as part of the recovery process. CISA also recommends regularly testing backup availability and integrity in disaster recovery scenarios.

A restore test gives the business more confidence that its website backup and recovery process will work when it is actually needed.

10. What Should a Website Restore Test Check?

A restore test should verify more than whether the homepage loads.

The restored website should be checked for important functions such as:

• Pages and posts
• Images and media
• Navigation menus
• Forms
• Database content
• Plugins or extensions
• Custom functionality
• User accounts where applicable
• HTTPS and certificate configuration
• Important integrations

Checking these areas can reveal problems that would not be obvious from viewing only one page.

Good website navigation should also be verified after restoration so users can still reach important services and pages.

11. Backups Should Be Protected From Unauthorized Access

Website backups can contain sensitive information.

Depending on the website, a backup may include customer information, user accounts, configuration details, database contents, API information, or other private data.

Backup storage should have appropriate access controls, strong authentication, and encryption where supported.

CISA recommends protecting backups so attackers cannot easily delete or modify them during an incident. Its guidance also highlights offline copies and protections such as object lock or delete protection where those technologies are available.

Our guide to website security basics covers related controls such as updates, HTTPS, access management, monitoring, and multifactor authentication.

12. Backups Matter Before Website Updates and Major Changes

Regular scheduled backups are important, but businesses may also want a fresh restore point before making significant changes.

These changes may include:

• Major WordPress or CMS updates
• Plugin or extension updates
• Theme changes
• Custom code deployments
• Website redesigns
• Hosting migrations
• Database work
• Large content imports

If a change causes an unexpected problem, a recent backup can make it easier to return to the previous working version.

13. Website Backups and Hosting Are Closely Connected

Hosting providers often include some type of backup feature, but the details can vary widely.

Businesses should not assume that every hosting plan includes the same backup frequency, retention period, storage location, or restoration process.

This is one reason it helps to understand the difference between hosting and other website infrastructure.

Our guide to domain vs hosting vs DNS explains how hosting, domain registration, and DNS perform separate roles even when one provider manages several of them.

14. Backups Should Be Part of a Recovery Plan

A backup is most useful when a business knows how it will be used.

A basic website recovery plan should identify:

• Where backups are stored
• Who has access to them
• Who is responsible for starting a restore
• Which backup should be selected
• How the website will be tested after restoration
• Who should be notified during an outage
• Which services need to return first

CISA recommends identifying critical systems and restoration priorities so recovery efforts can focus on the services that matter most to the organization.

Planning these steps before an incident can reduce uncertainty when the website is unavailable.

15. Businesses Should Know Who Is Responsible for Website Backups

Backup responsibility can become unclear when several vendors are involved.

A business may assume its web developer handles backups while the developer assumes the hosting provider handles them. The hosting provider may offer backups but retain them for only a limited period.

These assumptions should be replaced with documented answers.

16. Website Backup and Recovery Should Account for Recovery Time

Having a valid backup does not mean recovery will be instant.

Restoration may involve downloading data, rebuilding an environment, importing a database, updating DNS, checking SSL, reconnecting integrations, and testing the website.

Larger or more complex websites may take longer to recover than smaller brochure-style sites.

Businesses that depend heavily on their website should understand how quickly recovery could realistically happen and whether their current process supports that goal.

17. Website Performance Should Be Checked After Recovery

A restored website may technically work while still having performance problems.

Cache settings, server configuration, database changes, plugins, image optimization, or other technical settings may need to be reviewed after restoration.

Our article on factors affecting website speed explains several hosting and website factors that can influence loading performance.

Recovery should include checking important pages on desktop and mobile rather than assuming the site is fully restored once the homepage appears.

What Businesses Should Check About Their Website Backups

If a business cannot answer these questions, it may have backups without having a complete recovery process.

When Managed Website Backup Services Make Sense

Small website owners can sometimes manage backups themselves, but the process becomes more important as the website plays a larger role in marketing, lead generation, ecommerce, customer service, or daily operations.

Professional website backup services and website maintenance services may be useful when:

• No one regularly checks whether backups are completing
• The business does not know how to restore the website
• The website changes frequently
• Backups exist only on the production server
• The business needs multiple restore points
• Website updates are performed regularly
• Downtime could affect leads, customers, or revenue
• The business wants one team responsible for ongoing management

Managed website backup and recovery can combine automated backups, retention, monitoring, restoration support, hosting management, and ongoing website maintenance under a clearer process.

Website Backup and Recovery Should Be Tested Before an Emergency

The best time to discover a backup problem is before the website needs to be restored.

Businesses should know what their backups contain, where copies are stored, how often new restore points are created, and whether the recovery process has been tested.

Strong website backup and recovery planning does not prevent every website problem, but it can give a business a much clearer path back to a working site when something goes wrong.
