Abstract
A device is configured to index file system names and paths of a single chain of backed-up snapshots. The device is configured to obtain a first snapshot of the file system. Further, the device is configured to scan the first snapshot of the file system to obtain a first scan of the nodes and the tree structure at a first time point. The device is further configured to insert the first scan into a database. Then the device is configured to index the nodes in the database.
Claims20
A device for backing up a file system, comprising;
- an interface;
- and
- a processor coupled to the interface and configured to:
- obtain a first snapshot of a file system comprising a plurality of first nodes arranged into a first tree structure;
- scan the first snapshot to obtain a first scan of the first nodes and the first tree structure at a first time point;
- insert the first scan into a database;
- and
- index the first nodes in the database to obtain a node index.
A method comprising:
- obtaining a first snapshot of a file system comprising a plurality of first nodes arranged into a first tree structure;
- scanning the first snapshot to obtain a first scan of the first nodes and the first tree structure at a first time point;
- inserting the first scan into a database;
- and
- indexing the first nodes in the database to obtain a node index.
A computer program product comprising computer-executable instructions stored on a non-transitory computer readable storage medium that when executed by a processor, cause an apparatus to:
- obtain a first snapshot of a file system comprising a plurality of first nodes arranged into a first tree structure;
- scan the first snapshot to obtain a first scan of first nodes and a first tree structure at a first time point;
- insert the first scan into a database;
- and
- index the first nodes in the database to obtain a node index.
