Providing disaster recovery of a distribute file system metadata server as a service is disclosed. In various embodiments, an indication is received to provide alternative access to a file system metadata server. A copy of a self-describing backup of the file system metadata server is obtained, e.g., from cloud-based storage. The backup is used to provide access to a read only instance of the file system metadata server.

Disaster recovery as a service

A multilayer manifest enables any file written to an object store using a proprietary storage process, including large virtual machine backup images, to be recovered without being dependent on the proprietary storage process. Upon synchronizing a file written to an object store in cloud-enabled storage, a multilayer manifest process generates a family of manifest files in a self-contained format that represents all the necessary information required to reconstruct the file. The family of manifest files includes an ancestral record used to initiate retrieval of a file, and multiple layers of manifest files associated with the ancestral record. During retrieval, each of the one or more multilayer manifest files is successively reconstructed and used to securely retrieve the next manifest file until no further manifest files remain in the family. Reconstruction of the last multilayer manifest file results in the recovery of the file for which the manifest files were generated.

Multilayer manifest for data storage systems

A system and method for providing data protection services and lifecycle management in a Platform as a Service (PaaS) platform having cloud-based applications and data, by discovering an application installed on the PaaS platform using mechanisms native to the PaaS platform, associating the application and an associated data service used by the application to identify data created by the application, and performing a backup/restore operation on the application and the identified data in accordance with a defined schedule. The native mechanisms may comprise application programming interfaces (APIs) provided by the PaaS platform, or metadata associated with containers used by the PaaS platform. The schedule may be defined by RTO and RPO requirements of a user.

Data service protection for cloud management platforms

A computer-implemented method for indexing backup file metadata may include 1) identifying a request to perform a full backup of a volume, 2) identifying a file metadata index for previous backups of the volume, 3) adding a current key uniquely identifying the file within the full backup and an identifier of the full backup to the file metadata index, 4) comparing the current key to the file metadata index to determine whether the current key is represented in the file metadata index, and 5) adding file metadata to the file metadata index for each file within the volume that is uniquely represented by the current key of the file within the file metadata index. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for indexing backup file metadata

A computer-implemented method for enhancing electronic discovery searches may include (1) receiving a search query for at least one instance of a user being identified within a backup image of a volume of data, the search query being conducted for electronic discovery, (2) identifying metadata associated with the backup image specifying at least one action performed by the user on a computing system while the volume of data was mounted for use on the computing system, (3) performing the search query on the backup image and receiving a result of the search query in response to performing the search query, (4) enhancing the result of the search query with contextual information relating to the search query based on the metadata, the contextual information facilitating further electronic discovery, and (5) providing the enhanced result of the search query. Various other methods, systems, and computer-readable media are also disclosed.
