What Is Immutable Backup
What is immutable backup?
Invariant means that it cannot be changed.
Why Is Immutable Backup Important
Why is immutable backup important?
Immutable backups are not only useful in case of server failure.
They can also be used to protect against ransomware.
This post introduces different types of ransomware.
Besides, you might know how to prevent ransomware and how to protect your computers in this post.
While traditional forms of backups are effective, they are not foolproof.
Today, ransomware is designed to attack backups themselves, putting your data at more immediate risk.
Even with expensive security software and systems, backups can still be attacked.
Immutable object storage provides data security that is critical to many businesses.

How to protect your data from being attacked again?

How Does Immutable Backup Work
How does immutable backup work?
Immutable storage can be applied to data stored on traditional platforms such as disk or SSD.
Data saved in immutable cloud storage is protected by a write-once-read-many (WORM) mechanism.
When employees save files, they identify how long they want the files saved.
They can be kept indefinitely, but thats usually not the case.
Once they upload the data to the cloud, they set the immutability flag (selfie).
This flag locks the file in place for a while.
At that time, the file cannot be tampered with.
Benefits of Immutable Backup
The following are the benefits of immutable backup:
1.
Unlike traditional backups, you dont need to worry about immutable files being compromised.
Immutable storage keeps information safe and secure.
Consistent disaster protection
Immutable storage provides reliable protection against ransomware, natural disasters, outages, and more.
In this backup environment, your data is less vulnerable to virtual or physical tampering.
It provides peace of mind for many organizations that require this level of security.
Public Cloud
Backups can be stored on the public cloud as it enables you to make backups immutable.
Immutability in Linux
For Linux systems, Chattr commands allow you to store immutable data.
Backup solution providers are using this feature of Linux systems to allow users to create immutable backups.
Modern backup solutions allow you to set immutable flags on recovery points stored in Linux-based backup repositories.
Tape
Another backup storage option that supports immutability is tape.
Tape is an excellent storage medium for compliance retention and archiving.
LTO tapes are WORM capable, allowing you to preserve immutable backups by writing to the tape only once.
