Abstract

A method, article of manufacture, and apparatus for backing up or archiving objects from a first location to a second location, comprising determining the objects to be backed up and a prioritization of the objects according to a first criterion. The objects are transmitted from the first location to the second location substantially in accordance with the prioritization. The transmission may be suspended in accordance with loss of network connectivity, a user action, or throttling to reduce processor or network load. Transmission may be continued, and the objects reprioritized according to the first criterion, wherein relevant changes in the objects are reflected. A backup target may be chosen based on the location of the source, and if the location changes, a new backup target may be chosen in consideration of bandwidth. The backups to the backup targets may be combined to define a backup.

Claims

1. A method for backing up objects from a first location to a second location, comprising:

determining objects to be backed up and a prioritization of the objects according to a first criterion, the first criterion comprising a predicted usage interval derived from an object periodicity, the predicted usage interval comprising a next predicted time of usage for each of the objects;

adjusting the prioritization of the objects based on each object'"'"'s next predicted time of usage, wherein the objects with an earlier predicted time of usage are prioritized before objects with a later predicted time of usage;

transmitting the objects from the first location to the second location substantially in accordance with the prioritization;

suspending the transmission of objects from the first location to the second location, based on a non-persistent network connectivity;

continuing transmitting the objects; and

determining objects to be backed up and recalculating prioritization dynamically according to the first criterion, wherein relevant changes in the objects are reflected.

2. The method as recited in claim 1, wherein suspending the transmission of the objects is associated with a loss of network connectivity, a user action, or throttling to reduce processor or network load.

3. The method as recited in claim 1, wherein continuing transmitting the objects is performed in accordance with the reprioritization of the objects.

4. The method as recited in claim 1, wherein the first criterion further comprises at least one selected from the group comprising:

timestamp, object type, identity of object owner, and content.

5. The method as recited in claim 1, further comprising subsorting the prioritization of objects according to a second criterion.

6. The method as recited in claim 5, further comprising continuing transmitting the objects.

7. The method as recited in claim 6, further comprising determining objects to be backed up and reprioritization of the objects according to the second criterion.

8. The method as recited in claim 7, wherein continuing transmitting the objects is performed in accordance with the reprioritization of the objects.

9. A method for backing up objects from a source at a first location, comprising:

determining objects to be backed up and a prioritization of the objects according to a first criterion, the first criterion comprising a predicted usage interval derived from an object periodicity, the predicted usage interval comprising a next predicted time of usage for each of the objects;

adjusting the prioritization of the objects based on each object'"'"'s next predicted time of usage, wherein the objects with an earlier predicted time of usage are prioritized before objects with a later predicted time of usage;

transmitting the objects from the first location to the second location substantially in accordance with the prioritization;

suspending the transmission of objects from the first location to the second location, based on a non-persistent network connectivity;

continuing transmitting the objects; and

determining objects to be backed up and recalculating prioritization dynamically according to the first criterion, wherein relevant changes in the objects are reflected.

10. The method as recited in claim 9, further comprising detecting a change in the location, and determining, based on the first location, a second destination.

11. The method as recited in claim 10, further comprising transmitting the objects from the source at the changed location to the second destination.

12. The method as recited in claim 9, further comprising combining the objects from the second destination with the objects from the first backup target to define a backup for the objects at the source.

13. The method as recited in claim 9, wherein the determination of the first backup target comprises choosing the destination from a plurality of available destinations based on bandwidth to the available destinations.

14. The method as recited in claim 9, wherein the first criterion further comprises one selected from the group comprising:

timestamp, object type-identity of object owner, and content.

15. The method as recited in claim 9, further comprising subsorting the prioritization of objects according to a second criterion.

16. A computer program product for backing up objects from a first location to a second location, comprising a computer readable storage medium having machine readable code embodied therein for:

determining objects to be backed up and a prioritization of the objects according to a first criterion, the first criterion comprising a predicted usage interval derived from an object periodicity, the predicted usage interval comprising a next predicted time of usage for each of the objects;

adjusting the prioritization of the objects based on each object'"'"'s next predicted time of usage, wherein the objects with an earlier predicted time of usage are prioritized before objects with a later predicted time of usage;

transmitting the objects from the first location to the second location substantially in accordance with the prioritization;

suspending the transmission of objects from the first location to the second location, based on a non-persistent network connectivity;

continuing transmitting the objects; and

determining objects to be backed up and recalculating prioritization dynamically according to the first criterion, wherein relevant changes in the objects are reflected.
