Abstract
Embodiments for providing file immutability for cloud storage data in a deduplicating filesystem and using a new filesystem that is spawned to receive redirected live data, after which the old filesystem is expired. Data objects are stored in the cloud by defining a protection duration from a first date to a fixed future date, and applying a retention lock to one or more data objects stored in cloud storage during the protection duration, the retention lock preventing unauthorized deletion, modification or movement of the data. A renew threshold date is defined within the protection duration, and a new filesystem is spawned on this date. All new data is redirected to the new filesystem and locked for the protection duration, and the first file system is destroyed.
