Background: Immutable Storage
The rise of cyber attacks demands stronger protection of data and backups. This is why immutable
storage is becoming increasingly popular.
But immutability is nothing new at all. For those
who remember, it was already possible to prevent overwriting of audio cassettes by breaking out a tab on the top. What is new about immutability is its use in the
area of object storage, where data is write-protected for a certain period of time by so-called object locking. However, automatic snapshots, WORM sealing and Air Gap are also methods of storing data “immutably” and thus protecting it from unintentional or unauthorized deletion or manipulation. So what matters?
