主权项

1. A system for save set indexing outside of backup windows, the system comprising:
a processor-based application executed on a computer and configured to:
discover a plurality of un-indexed snapshots of a save set, the un-indexed snapshots being a subset of all snapshots managed by backup application, each un-indexed snapshot being created without an index of the save set;mount a first snapshot of the plurality of snapshots on a proxy host in order to recreate the save set on the proxy host after the first snapshot has been created;parse the recreated save set on the proxy host to identify contents of the recreated save set;create the index of the identified contents to function as the index of the save set for the first snapshot;un-mount the first snapshot; andcreate an index for a second snapshot of the plurality of un-indexed snapshots based on the index of the first snapshot, the second snapshot being created without mounting the second snapshot by reusing common index entries with the index of the first snapshot and adding index entries to the index for the second snapshot based on detected differences between the first snapshot and the second snapshot.
