A backup is only useful if it actually works when you need it. The 3-2-1 rule is a widely adopted standard that defines how many copies of your data you should have, where they should be stored, and why that distribution matters.
This article explains the principle and how it applies to your mybox account.

What the 3-2-1 rule means
The rule is simple:
- 3 copies of your data in total
- 2 stored on different types of media
- 1 stored off-site (outside your primary location)
The logic is redundancy. If one copy fails or is destroyed, you have others. If two copies are in the same physical location and that location is affected - fire, flood, theft - the off-site copy remains intact.
How mybox handles backup automatically
Every mybox account includes an automatic daily backup. The backup runs overnight and is available for restore the following day. You do not need to configure anything - the backup happens in the background.
To restore your data, go to the Backup section in your mybox panel and submit a restore request. You do not need to contact support to initiate a restore.
| Plan | Frequency | Retention | Restore method |
| One Box | Daily (overnight) | 1 day | Self-service via panel |
| Flex Box | Daily (overnight) | 7 days | Self-service via panel |
| Prime Box | Daily (overnight) | 7 days | Self-service via panel |
Flex Box and Prime Box accounts allow you to restore from any of the previous 7 daily snapshots - useful when an issue goes unnoticed for several days.
Why the automatic backup is not enough on its own
The mybox backup covers most common scenarios - accidental file deletion, a failed update, a corrupted database. However, it does not cover every situation:
- Changes made and lost within the same day are not recoverable from the backup
- The backup copy is stored on mybox infrastructure - it is not an off-site copy in the 3-2-1 sense
For projects where data loss has serious consequences, consider maintaining an additional copy outside of mybox - for example, a local download of your files and a database export stored on an external drive or a separate cloud service. This brings your setup closer to the full 3-2-1 standard.
Practical backup habits
Regardless of what your hosting provider backs up automatically, a few habits reduce risk significantly. Export your database before making major changes. Download a copy of your files before updating themes or plugins. Test your backups periodically by verifying that a restore actually works.
