Immutability may be not enough

22 June 2024
No comments

Reading Time: 5 minutesLot of storage, cloud and backup solutions are promising some kind of data immutability. Of course, immutability is an important key capability, but it does not imply automatically that your solution is secure (or more secure). It can give a false sense of security if not implemented properly. When misconfigured, it is possible to delete supposedly immutable data, for example, by manipulating time/date settings on the storage device to bypass retention enforcement mechanisms.

Shared responsibility model in cloud services

Reading Time: 3 minutesIn a public cloud there can be different service models, but in all of them there is a common concept called: shared responsibility model. What does it means?

What is MAID?

16 April 2024
No comments

Reading Time: 4 minutesMAID (Massive Array of Idle Disks) is a new storage technology for long-term, online storage of persistent data that takes advantage of a newer generation of SATA (Serial Advanced Technology Attachment) disk drives that are designed to be powered on and off and improve energy efficiency. This allows denser packaging of drives in large-scale disk storage systems since only 25% of disks are spinning at any one time. MAID provides for the power management of disks drives, thus creating a new service level for retaining and accessing “archive/persistent” data.
