Recovery of application from snapshot

A computer program product comprising at least one computer-readable storage device having stored thereon computer-executable instructions that are structured such that, when executed by one or more processors of a computing system, cause the computing system to perform a method for recovering application specific data corresponding to an application, the method comprising:

• an act of determining that an application-specific data container is to be recovered from a snapshot, the application-specific data container comprising data that corresponds to a particular application, the snapshot comprising data from an operational volume comprising data in addition to data corresponding to the application-specific data container;
• in response to the act of determining, initiating recovery of a prior state of content of the application-specific data container from the snapshot by beginning to copy a prior version of the content from the snapshot to the application-specific data container in the operational volume while not recovering the data in addition to the data corresponding to the application-specific data container, such that only the prior state of content of the application-specific data container is recovered from the snapshot;
• tracking progress of copying of the prior version of the content from the snapshot to the application-specific container;
• tracking at least one address region corresponding to a write request that is made on the application-specific container in the operational volume apart from the recovery;
• and
• skipping the at least one address region when arriving at the at least one address region in the recovery.

A system in which targeted recovery of an application may occur without recovering the entire system, the system comprising:

• one or more computer processors;
• and
• computer memory having stored therein computer-executable instructions for performing steps for recovering application specific data corresponding to an application, the computer-executable instructions, when executed on the one or more computer processors, causing the system to be configured to perform:
• determining that an application-specific data container is to be recovered from a snapshot, the application-specific data container comprising data that corresponds to a particular application, the snapshot comprising data from an operational volume comprising data in addition to data corresponding to the application-specific data container;
• in response to determining, initiating recovery of a prior state of content of the application-specific data container from the snapshot by beginning to copy a prior version of the content from the snapshot to the application-specific data container in the operational volume while not recovering the data in addition to the data corresponding to the application-specific data container, such that only the prior state of content of the application-specific data container is recovered from the snapshot;
• while the prior version of the content of the application-specific data container is being copied from the snapshot to the application-specific data container, permitting the particular application to perform read and write operations on the application-specific data container.
