Backup problems rarely announce themselves. You usually only discover them at the worst possible moment — when you actually need to restore your site and the backup either does not exist, is incomplete, or will not restore cleanly.
Here are the most common issues and what causes them.
The most common WordPress backup problems
- Backups stopped running silently — A configuration change, a failed authentication with the storage destination, or a server timeout can cause backups to stop without any visible error. Without monitoring or notifications, this goes unnoticed for weeks or months
- Incomplete backups — Some setups back up only the database and miss the files, or vice versa. A partial backup cannot fully restore a site
- Backups stored on the same server — If the hosting server is compromised, corrupted, or goes offline, backups stored on that same server are lost with it
- Backups that time out on large sites — Sites with large media libraries can exceed server time limits during backup, resulting in incomplete or failed backup files
- Restore failures — A backup file that exists does not guarantee a successful restore. Corrupted archives, database import errors, or mismatched configurations can all cause a restore to fail mid-process
- No retention policy — Keeping only the most recent backup means that if a problem is introduced and not caught immediately, you have no earlier restore point to fall back on
The fix is not a better plugin
Most of these problems are not solved by switching tools. They are solved by having someone who actually monitors the backup system, verifies it regularly, and tests restores before they are needed.
If you are unsure whether your backups are actually working, a website checkup covers this as standard. Backup monitoring is also part of our WordPress maintenance service. Read more in the backups knowledge base.
