Implementing an immutable data vault
One of the best ways to safeguard your data is to implement immutable and indelible storage. This type of storage ensures that data cannot be changed, encrypted, or deleted for a determined length of time (or at all). NetBackup and NetBackup appliances provide secure and tamper-resistant immutable and indelible storage to protect data backups from being tampered with and from unauthorized access.
You can store immutable data in the cloud on object storage, including FortKnox for NetBackup or with third-party OpenStorage Technology (OST) vendors. FortKnox for NetBackup also creates a separation of duties where Cohesity manages the administration of the storage and provides you another layer of isolation from attack.
These features are vital to an effective and a rapid recovery strategy.
With the addition of immutability, Cohesity now recommends a new strategy for backups. In the past, the recommendation was a 3-2-1 strategy: three copies of data, two on site on different media, and one copy off site. The current rise in cyber threats calls for an extra "1," creating a 3-2-1+1 strategy: three copies of data, two on site on different media, one copy off site, and one copy that is immutable.
