Data de-duplication

A new snapshot of a storage volume is created by suppressing write requests. Once pending write requests from the computing nodes are completed, storage nodes create a new snapshot for the storage volume by allocating a new segment to the new snapshot. Subsequent write requests to the storage volume are then performed on the segments allocated to the new snapshot. An orchestration layer implements a bundled application that is provisioned with storage volumes and containers. A snapshot of the application may be created and used to rollback or clone the application. De-duplication may be performed by creating a signature map and identifying duplicated blocks. Blocks of segments containing duplicated blocks are copied to pool segments and metadata of those segments of the same logical storage unit may be consolidated to pool metadata segments. The identification of duplicate blocks may be performed in a cloud computing platform.
