S3 Object Lock for Immutable Backup

Protect your business from data loss with immutable storage that can be immediately deployed back into your production storage after a ransomware attack or accidental deletion or alteration.

What is Object Lock?

Creating a data storage air gap by physically removing your backups from the network (aka on site tape backup and hard drives) may seem like the safest way to protect your data, but it is hardly practical when you need to quickly restore your data in the event of a ransomware attack, equipment failure, human error or natural disaster.

Immutable storage with S3 Object Lock is the modern equivalent of the air gap. It creates a logical air gap through encryption and hashing, which makes data immutable to malicious efforts to encrypt or delete it. Immutable objects, locked individually by an application or as part of an overarching policy with Wasabi's immutable storage buckets, cannot be deleted or altered in any way, not even by a system administrator.

With Wasabi S3 Object Lock, your data is secure, offsite, and available at a moment’s notice should you need immediate access to your backups.

Why should you Use S3 Object Lock for immutable backups?

It is increasingly difficult to defend against bad actors, ensure the chain of custody and regulatory compliance of data, or prevent catastrophic data loss due to human error. Immutable storage enables you to make your data impervious to unauthorized or accidental revisions and deletion. Malicious actors cannot encrypt object-locked data and hold it for ransom.

In cases where you have multi-year retention requirements, you can set a fixed retention period to ensure those assets are securely protected for the duration of time required by governance or compliance requirements. Object Lock's immutable storage prevents unwanted revisions or deletions for all your stored data, for as long as you want to protect it, and is available to Wasabi customers at no additional cost.
