Losing business data is stressful. But having a cloud backup doesn’t automatically mean you can recover everything when something goes wrong. Unless you regularly test your cloud backups, they might not restore everything you need.
What is cloud backup?
Cloud backup is a copy of your business data stored securely away from your main systems. If files are accidentally deleted, corrupted, lost or affected by a cyber attack, the backup gives you a way to recover them.
Unlike cloud storage, which is primarily designed for accessing and sharing files, cloud backup is designed for recovery.
Is cloud backup secure?
A properly configured cloud backup can provide strong protection against data loss, but not all backup systems are the same.
It is important to look for features such as encryption, access controls, MFA, retention policies and protection against backup deletion. Your backup should also be separated from the systems it is protecting, so an attacker who compromises your network cannot simply delete the backup too.
What is the 3-2-1 backup rule?
The 3-2-1 backup rule means keeping:
- 3 copies of your data
- On 2 different types of storage
- With 1 copy kept off-site
Cloud backup can provide that off-site copy, but the important point is to avoid having a single backup that represents your only way of recovering your business data.
How often should a business back up its data?
It depends on how much data your business could afford to lose.
If losing a day’s work would cause a serious problem, a daily backup may not be enough. More frequent or continuous backups can reduce the amount of data you could lose between backups.
Think about how much data you could realistically afford to lose, rather than simply choosing a backup schedule because it is convenient.
Can I recover deleted files from a cloud backup?
Usually, yes provided your backup retention policy still includes the deleted data. If a file is deleted today and your backup system immediately removes every copy, there may be nothing to restore. A suitable retention period gives you a recovery window if someone deletes a file accidentally or discovers the loss several days later.
What happens if ransomware encrypts my files?
This is where a good backup can become your last line of defence. If ransomware encrypts the files on your network, you may be able to restore clean versions from a backup created before the attack. However, the backup itself needs protection. If ransomware can access and encrypt or delete your backups, they may not help you recover.
That is why isolated, protected and tested backups are so important.
How often should I test my cloud backups?
Regularly, because a backup you have never restored is an assumption, not proof of recovery.
Businesses should test both that backups are completing successfully and that data can actually be restored. The right frequency depends on the importance of the data, but testing at least quarterly is a sensible starting point for many businesses.
The test should go beyond checking that a backup says “successful”. Actually restore files and confirm they are usable. For critical systems, test more frequently and include a realistic recovery scenario.
