Described herein are systems and methods for replication and moving data to provide for container-based application mobility. The configuration of the of the container-based application is determined and copied to an intermediate object storage. Depending on the replication compatibility of source array backing the source cluster and the target array backing the target cluster either a replication engine or data mover are used to move data. Configuration of the container-based application in the common storage is copied and stored to the target cluster. The target cluster is used to restore the container-based application.

Method and system for temporary replication as data mover for container-based application mobility

A method comprises requesting and receiving from a cloud mobility platform metadata for accessing one or more file systems which have been tiered to cloud storage, and writing the metadata to at least one backup storage location. In the method, a plurality of stub files are read, the plurality of stub files corresponding to a plurality of files of the one or more file systems which have been tiered to cloud storage. The plurality of stub files are written to the at least one backup storage location.

Data protection for stub files and cloud metadata

Techniques for container environment management are disclosed. For example, a method manages, via a virtual container storage interface controller, a generic mapping for one or more container storage attributes for a set of storage specific container storage interface drivers respectively associated with a set of storage arrays of a storage system so as to isolate an application program, executing on a host device accessing one or more storage volumes stored on the set of storage arrays, from the set of storage specific container storage interface drivers. For example, the isolation can provide a layer of abstraction for application specific handles from the actual underlying storage and then enable use of the abstraction to provide services such as, but not limited to, seamless data mobility.

Virtual container storage interface controller

A method is disclosed of copy-free, non-disruptive conversion of a storage volume from a first access protocol to a distinct second access protocol. In a preparatory step a destination volume accessible according to the second access protocol is created. A pairing of a token and a handle is created, the token representing data content of the source volume, the handle being associated with the token and usable to represent the source volume according to the second protocol. In response to a subsequent copy-with-handle command, and based on the pairing of the handle with the token, metadata of the destination volume is populated to reference, without copying, the underlying stored data, the destination volume thereafter functioning as the storage volume accessed using the second protocol.
