Abstract

Systems and methods are disclosed for cross-system user-level management of data objects stored in one or more information management systems, and for user-level management of data storage quotas in information management systems, including data objects in secondary storage. An illustrative quota manager is associated with one or more information management systems. The quota manager comprises a quota value representing the maximum amount of data storage allowed for a given end-user'"'"'s primary and secondary data in the one or more information management systems. The quota manager determines whether data associated with the end-user has exceeded the storage quota, and if so, prompts the end-user to select data for deletion, the deletion to be implemented globally, across the primary and secondary storage subsystems of the respective one or more information management systems. Meanwhile, so long as the quota is exceeded, the quota manager instructs storage managers to block backups of end-user'"'"'s data.

Claims

1. A system comprising:

a quota manager in communication with a storage manager that manages an information management system;

wherein the quota manager is configured to;

determine, based on information received from the storage manager, a total amount of storage that is occupied by data associated with an end-user in the information management system,

wherein the data associated with the end-user comprises at least one of;

an instance of an object of primary data stored in primary storage and an instance of a secondary copy object stored in secondary storage, and

identify, based on a selection of data received from the end-user, one or more instances of one or more data objects,

wherein the one or more identified instances comprise at least one instance of a secondary copy object that is associated with the end-user and is stored in secondary storage of the information management system,

instruct the storage manager to implement one or more deletion operations of the one or more identified instances, and

following the one or more deletion operations, adjust the total amount of storage that is occupied by the data associated with the end-user in the information management system.

2. The system of claim 1 wherein the quota manager is further configured to:

based on a determination that the total amount of storage exceeds a quota value for the end-user, instruct the storage manager to block a backup operation for one or more objects of primary data associated with the end-user.

3. The system of claim 1 wherein the quota manager is further configured to:

based on a determination that the total amount of storage exceeds a quota value for the end-user, instruct the storage manager to block a backup operation for one or more objects of primary data associated with the end-user, and

based on a determination that the adjusted total amount of storage no longer exceeds the quota value for the end-user following the one or more deletion operations, instruct the storage manager to unblock the backup operation.

6. The system of claim 1 wherein the quota manager comprises a quota value for the end-user of the information management system,

the quota value defining an amount of data storage, comprising primary storage and secondary storage in the information management system, that may be occupied by data associated with the end-user, and

wherein the quota manager is further configured to:

based on a determination that the total amount of storage exceeds the quota value for the end-user, prompt the end-user to provide the data selection for deletion,

wherein the prompt comprises representations of unique data objects associated with the end-user across the information management system, and

wherein a representation of a unique data object corresponds to at least one instance of a secondary copy object.

7. A system comprising:

at least one processor;

a quota manager; and

a first storage manager in communication with the quota manager, wherein the first storage manager manages a first information management system comprising data that is associated with an end-user;

wherein the quota manager is configured to;

store a quota value for the end-user, the quota value defining an amount of data storage that may be occupied by data associated with the end-user,

determine, based on information received from the first storage manager, a total amount of storage that is occupied by data associated with the end-user,

wherein the data associated with the end-user comprises at least one of;

an instance of an object of primary data stored in primary storage and an instance of a secondary copy object stored in secondary storage,

determine whether the total amount of storage exceeds the quota value for the end-user, and

based on a determination that the total amount of storage exceeds the quota value for the end-user, instruct the first storage manager to block a backup operation for one or more objects of primary data associated with the end-user.

8. The system of claim 7, wherein the quota manager is further configured to:

identify, based on a selection of data received from the end-user, one or more instances of one or more data objects,

wherein the one or more identified instances comprise at least one instance of a secondary copy object stored in secondary storage of the first information management system, and

instruct the first storage manager to implement one or more deletion operations of the one or more identified instances.

9. The system of claim 8, wherein the quota manager is further configured to:

following the one or more deletion operations, based on a determination that the total amount of storage no longer exceeds the quota value for the end-user, instruct the first storage manager to unblock the backup operation.

10. The system of claim 7 further comprising:

a second storage manager in communication with the quota manager, wherein the second storage manager manages a second information management system comprising data associated with the end-user, and

wherein the total amount of storage that is occupied by data associated with the end-user comprises an aggregate of a first amount of storage that is occupied by data associated with the end-user in the first information management system and a second amount of storage that is occupied by data associated with the end-user in the second information management system.

11. The system of claim 10, wherein the quota manager is further configured to:
