Method and system for volume based snapshot restore

摘要

Method and system is provided to perform a plurality of checks before performing a volume based snapshot restore (“VBSR”) operation. The checks may be performed by an application executed at a computing system that interfaces with a storage system. The application may determine if there are any inconsistent LUNS and foreign mapped LUNs. The application may also determine if there are any new LUNs or any new snapshots since the snapshot, which is the basis of the restore operation was created. The application may further determine if there are any backup relationships with respect to a volume that is being restored. The application takes the information and provides a report to a user. The report allows a user to ascertain the consequences of proceeding with the VBSR operation.

主权项

1. A machine implemented method, comprising:
maintaining a data structure for a point in time copy of a storage volume for storing information regarding any foreign mapped logical object and any inconsistent logical object; wherein an inconsistent logical storage object is a storage object used by a second file system and not by a first file system that is included in the point in time copy; and wherein a foreign mapped logical object is a storage object that is not a part of an active file system and was not present when the point in time copy was generated; conducting a plurality of checks using the data structure, before a restore operation is performed based on the point in time copy by a processor executable application at a computing system interfacing with a storage system managing the storage volume for determining an impact of the restore operation; presenting by the application a consolidated report indicating a status of passed and failed checks from among the plurality of checks; and providing an option to a user, based on the consolidated report, to take preventive action to reduce any potential damage due to the restore operation.
