A data management and storage (DMS) cluster of peer DMS nodes manages migration of an application between a primary compute infrastructure and a secondary compute infrastructure. The secondary compute infrastructure may be a failover environment for the primary compute infrastructure. Primary snapshots of virtual machines of the application in the primary compute infrastructure are generated, and provided to the secondary compute infrastructure. During a failover, the primary snapshots are deployed in the secondary compute infrastructure as virtual machines. Secondary snapshots of the virtual machines are generated, where the secondary snapshots are incremental snapshots of the primary snapshots. In failback, the secondary snapshots are provided to the primary compute infrastructure, where they are combined with the primary snapshots into construct a current state of the application, and the application is deployed in the current state by deploying virtual machines on the primary compute infrastructure.

Application migration between environments

Methods, systems, and devices for data management are described. A data management system (DMS) may receive a request to access metadata stored in a distributed metadata repository. The request may have a first semantic format compatible with a first version of the distributed metadata repository. The DMS may translate the first semantic format of the request to a second semantic format compatible with a second version of the distributed metadata repository. The DMS may perform the semantic translation according to a label in the request. Accordingly, the DMS may determine whether a current version of the metadata corresponds to the first version of the distributed metadata repository or the second version of the distributed metadata repository, and may access the metadata in the distributed metadata repository based on the request and the current version of the metadata.

Techniques for upgrading and accessing metadata

A data management and storage (DMS) cluster of peer DMS nodes manages data of an application distributed across a set of machines of a compute infrastructure. A DMS node associates a set of machines with the application, and generates data fetch jobs for the set of machines for execution by multiple peer DMS nodes. The DMS node determining whether each of the data fetch jobs for the set of machines is ready for execution by the peer DMS nodes. In response to determining that each of the data fetch jobs is ready for execution, the peer DMS nodes execute the data fetch jobs to generate snapshots of the set of machines. The snapshots may be full or incremental snapshots, and collectively form a snapshot of the application.

Application backup and management

Methods and systems for backing up and restoring different point in time versions of a virtual machine, an application, a database, or an electronic file using independently managed snapshot chains are described. In some cases, different point in time versions of a virtual machine may be captured and stored using one or more snapshot chains. Each snapshot chain may correspond with a base image (e.g., a full image snapshot) and one or more incremental files (e.g., two forward incremental files) that derive from the base image. A snapshot chain may be split into a plurality of shards or sub-chains such that the width of each shard or the maximum data size of the files in each shard is less than a threshold data size (e.g., is less than 1 TB). Data operations (e.g., consolidation and reverse operations) may be performed on the individual shards or sub-chains in parallel.
