US 9,519,432 B1 · Self-adjusting backup operations

Abstract

Performing automated and self-adjusting backup operations by executing the following steps: Determining a time of last backup operation for a data block. Obtaining an audit trail based on the time of last backup operation for the data block and a current time. Ordering read operations and write operations of the data block into a chronological sequence based on the audit trail. Generating a weighting element for read operations and a weighting element for write operations of the data block such that a weighting of read operations are greater than or less than the weighting of a write operations. Calculating a weighted sum of weighted read operations and weighted write operations for said data block. Respond to a result of a comparison between the weighted sum and at least one threshold value by performing a type of backup operation.

Dependent claims

A method of performing automated and self-adjusting backup operations, the method comprising:

determining, by a processor, a time of last backup operation for a data block;
obtaining, by the processor, an audit trail based, at least in part, on the time of last backup operation for the data block and a current time;
ordering, by the processor, one or both of read operations and write operations of the data block into a chronological sequence based on the audit trail;
generating, by the processor, a first weighting element for read operations and a second weighting element for write operations of the data block such that a weighting of a given read operation is greater than or less than a weighting of a given write operation;
calculating, by the processor, a weighted sum of weighted read operations and weighted write operations for said data block;
and
responsive to a result of a comparison between the weighted sum and at least one threshold value, performing, by the processor, a type of backup operation.
