International Classification:

G06F 12/16
G06F 13/00

US Classification:

711162, 711159, 711161

Abstract:

A persistent snapshot is taken and maintained in accordance with a novel method and system for extended periods of time using only a portion of a computer readable medium of which the snapshot is taken. Multiple snapshots can be taken in succession at periodic intervals and maintained practically indefinitely. The snapshots are maintained even after powering down and rebooting of the computer system. The state of the object of the snapshot for each snapshot preferably is accessible via a folder on volume of the snapshot. A restore of a file or folder may be accomplished by merely copying that file or folder from the snapshot folder to a current directory of the volume. Alternatively, the entire computer system may be restored to a previous snapshot state thereof. Snapshots that occurred after the state to which the computer is restored are not lost in the restore operation. Different rule sets and scenarios can be applied to each snapshot.

Multiple snapshots can be taken in succession at periodic intervals and maintained practically indefinitely.

Alternatively, the entire computer system may be restored to a previous snapshot state thereof. Snapshots that occurred after the state to which the computer is restored are not lost in the restore operation. Different rule sets and scenarios can be applied to each snapshot. Furthermore, each snapshot can be written to within the context of the snapshot and later restored to its pristine condition. Software for implementing the systems and methods of snapshots in accordance with the present invention may comprise firmware of a hard disk drive controller or a disk controller board or within the HDD casing itself. The present invention further comprises novel systems and methods in which the systems and methods of taking and maintaining snapshots are utilized in creating and managing temporal data stores, including temporal database management systems. The implications for data mining and exploration, data analysis, intelligence gathering, and artificial intelligence (just to name a few areas) are profound.

International Classification:

G06F007/00

US Classification:

707/100000

Abstract:

A temporal data store includes one or more data groups in an online archive or snapshot systems. Each data group in turn includes a plurality of members, data of each of which is preserved in a finite data storage having a fixed, predetermined storage capacity. Each data group further has associated therewith a time point, and each member of each data group has associated therewith a preservation weight. Upon detecting that finite data storage consumption has reached a first level, then for each member in order of increasing preservation weight beginning with the one or more members having the lowest preservation weight, successively deleting each member in increasing chronological order beginning with the oldest member first, until the finite data storage consumption has reached a second lower level. Each member of the data group may include a snapshot or a backup.

International Classification:

G06F012/00

US Classification:

707/204000

Abstract:

A method of managing the recordation of data sets to a finite data storage medium, each respective data set having associated therewith a time of creation and a preservation weight from a range of allowable preservation weights, comprises detecting that the finite data storage medium has reached or exceeded its effective capacity; for all data sets currently stored in the finite data storage medium, successively deleting each respective data set with the lowest preservation weight and earliest time of creation until the finite data storage medium is below a threshold capacity; and once below the threshold capacity, recording a new data set to the finite data storage medium. In a further aspect, when all data sets remaining in the data storage medium are identified as permanent and the data storage medium is still at or above its effective capacity, an error message is returned and no new data set is recorded. In a further aspect, a method of managing groups of data sets comprises associating a new data set to a predetermined group, recording the new data set to the finite data storage medium; and if the number of data sets stored in the finite data storage medium and associated with the predetermined group exceeds a maximum value, deleting the oldest data set of the predetermined group.
