Abstract: One example method includes scanning a storage device to obtain data and metadata concerning operation of a computing system, analyzing the data and, based on the analyzing, deriving data groups that include some of the data, and deriving data relationships among some of the data, receiving, by an expert system, a query from a user, and the query specifies a sample object for the expert system to investigate, but the query does not indicate purpose of the user in submitting the query, analyzing the query, based on the data groups and data relationships, and based on the analyzing of the query, generating, by the expert system, query results that comprise a set of user-selectable investigation directions that relate to the sample object, and presenting, by the expert system, the set of user-selectable investigation directions to the user.

Abstract: One example method includes ingesting data to a data protection system, separating, by the data protection system, the ingested data into groups according to Recovery Point Objective (RPO) such that each group is associated with a different respective RPO, storing the groups in respective storage pools, and each of the storage pools is associated with a respective one of the RPOs, and performing a respective garbage collection (GC) process at each storage pool.

Abstract: A security level tagging process to enable a user to associate a security level descriptor with a file, or a namespace directory where files and subdirectories inherit the security level descriptor from a parent directory. A parser can be used to automatically set a security level descriptor based on the contents of the file and/or attributes of files, or an administrator can associate a security level to a storage tier in the file system so that files are placed on the storage tiers with the matching security level as the file security level descriptor. The placement of the file on a storage tier depends on the data security level descriptor of the file and the security level of the storage so that files are placed on tiers where security level associated with the tier is greater than or equal to data security level of the file. Files can be migrated among storage tiers as their security levels may change.

Abstract: A system and method for managing data includes identifying, in response to a storage request from a tenant system, a first data protection pool based on a data classification analysis performed on data associated with the storage request and initiating storage of data associated with the storage request in a first storage system associated with the first data protection pool. A pattern matching model and data sampled from the tenant system may be used to identify data characteristics, which may include data type, data retention, data sensitivity, and data location. At least some data characteristics may be obtained using a plugin to a tenant system on which the data associated with the storage request is stored.

Abstract: A method and system for dynamic data protection. Specifically, the method and system disclosed herein provide and manage tiers of licensed storage capacity on which backup data may be consolidated. The particular tier of licensed storage capacity on which backup data may be consolidated may be dependent on the characteristics of the backup data. In cases where there may be insufficient available capacity in a licensed storage capacity tier to consolidate the backup data, a remaining capacity lacking in the licensed storage capacity tier may be overdrawn from another licensed storage capacity tier, provided that the latter tier has enough unallocated capacity to subsume the lacking capacity.
