Generating mapping information for single snapshot for multiple applications

An information management system configured to generate a snapshot of data relating to a plurality of applications, the system comprising:

• a primary storage device comprising a logical volume;
• a client computing device configured to execute a first data agent, the first data agent being associated with a first application executing on the client computing device, the client computing device further configured to execute a second data agent, the second data agent being associated with a second application executing on the client computing device, data generated by the first application and data generated by the second application being stored in the logical volume in the primary storage device;
• and
• a second computing device configured to execute a snapshot manager, the snapshot manager configured to:
• communicate with the first data agent to check whether the first application is in a consistent state and communicate with the second data agent to check whether the second application is in a consistent state;
• and
• in response to receiving a first notification from the first data agent that the first application is in a consistent state and a second notification from the second data agent that the second application is in a consistent state:
• obtain a snapshot of the logical volume;
• copy the snapshot of the logical volume to secondary storage using one or more media agents;
• receive first metadata from the first data agent via the client computing device, the first metadata relating to how a first directory that corresponds with the first application is organized, wherein the first directory is in a file system associated with the logical volume;
• receive second metadata from the second data agent via the client computing device, the second metadata relating to how a second directory that corresponds with the second application is organized, wherein the second directory is in the file system associated with the logical volume;
• determine a first location within the snapshot that corresponds with how the first directory that corresponds with the first application is organized as indicated in the first metadata;
• determine a second location within the snapshot that corresponds with how the second directory that corresponds with the second application is organized as indicated in the second metadata;
• generate first mapping information that identifies the first location within the snapshot as a location where the data generated by the first application is stored;
• and
• generate second mapping information that identifies the second location within the snapshot as a location where the data generated by the second application is stored.
