Data Lock for preventing malicious or accidental deletion of snapshots

Heads up!

We've transitioned to a new documentation portal to serve you better. Access the latest content by clicking here.

Ransomware attacks are increasing at an exponential rate. Backup environments are popular targets for ransomware attacks. There can be various reasons when the backup copies can be modified or deleted. When it comes to protecting your data in the event of a ransomware attack, snapshots are critical components of your organization’s business strategy and data recovery plan. 

Organizations can enable Data Lock to prevent modification, deletion, or tampering of business-critical data and make it immutable. Immutability has gained widespread attention with rising ransomware attacks that put enterprise data and business continuity at huge risk.

The following infographic displays how an immutable backup set responds to a threat from rogue admin or ransomware compared to a mutable backup set.



  • Provide complete protection to the backed-up data from rogue admin threats.

  • After applying the Data Lock, no one can delete, modify, or encrypt the snapshots. 

  • Alert notification and confirmation emails for any suspicious modification to the Data Lock settings. 

Use cases

Rogue Admin

Let’s say your organization’s rogue administrator, who is a super admin or any person who has acquired the compromised super admin credentials, gains access to your backup environment and manually deletes the snapshots. Data Lock prevents modification, deletion, or tampering of such critical data.


Ransomware Attack

Let’s say your organization's administrator or any employee received an email from an unidentified source and for some reason, clicked on the attachment present in this phishing email. Since the ransomware attacker has access to your backup environment, they can modify or delete your snapshots. Data Lock will prevent the deletion or modification of snapshots.

Accidental deletion

When your organization’s administrator with access to the backup management interface accidentally deletes or reduces the intended retention period, this results in the loss of snapshots. In the process, some business-critical snapshots may be accidentally deleted. Data Lock will prevent the accidental deletion of such data.
