Abstract:
A mechanism is provided in a data processing system comprising at least one processor and at least one memory, the at least one memory comprising instructions which are executed by the at least one processor and configure the processor to implement a snapshot utility for generating a snapshot of an erasure coded object in an object storage environment. Responsive to receiving a request to generate a snapshot of an erasure coded (EC) object in a filesystem in the object storage environment, the snapshot utility obtains a list of EC fragments from a proxy layer of the object storage environment. The snapshot utility copies a number of the EC fragments to generate the snapshot of the EC object.
