What is Wasabi Object Lock?

While offline tape backups or hard drives may seem like the safest place for all your essential data, removing them from the network means restorations can take many hours or even days. 

With cyberattacks, equipment failure, natural disasters, and plain old human error, you never know when you’ll need your backups to go live. Hours or days of downtime just won’t do.

Immutable storage increases cyber resilience

With Wasabi Object Lock, your data is secure, offsite, and available at a moment’s notice should you need immediate access to your backups. It’s also free with Wasabi, with no added API request charges or hidden fees to enable Object Lock or recover data.

Check out answers to these frequently asked questions about Wasabi S3 Object Lock.

Object lock is a data storage feature of Wasabi Hot Cloud storage that allows customers to designate certain objects to be immutable, meaning they cannot be altered or deleted by any application or user during a fixed date range defined by the user.

Immutable storage is a class of data storage which cannot be altered or deleted until the end of a set period of time.

Immutable storage is recommended as part of a ransomware and cybersecurity strategy that includes spreading data backups across multiple storage mediums, including an immutable backup copy of critical data, to avoid having a single point of failure within your system.

Immutable storage cannot be altered or deleted by anyone, including Wasabi engineers. All immutable storage is created with a set retention period and at the end of this period the data stops being immutable. Once the files are no longer immutable, they can be deleted.

Data stored with Wasabi can be made immutable through Wasabi Object Lock or by placing it in an immutable bucket.

Object lock enables customers to customize immutability and retention periods for each individual object. This granular control makes object lock an excellent fit for data that needs to be protected but may change over its lifetime, like backup data.

In an immutable bucket, all objects share the same immutability and retention settings. Immutable storage buckets are ideal for long-term protection of data such as archives and primary data storage as well as an important element in a ransomware protection strategy.

With compliance mode, a protected file or object can’t be overwritten by anyone, including any level user or even Wasabi engineers. When an object is locked in compliance mode, its retention date can’t be shortened, and it will remain immutable until the end of its retention period.

With governance mode, only users with special permission, such as the root user in the account can reduce the retention settings. This allows you to grant special permission to some users if necessary.

There is no additional charge for using Object Lock and immutable storage with Wasabi.

No. To use Wasabi Object Lock it must be enabled at the time a bucket is created. Buckets using object lock must also have versioning enabled. This is the same process required when using AWS S3.
