Schedule based data lifecycle management

摘要

A system and method for defining a separate lifecycle policy for each of one or more data images. A backup server is configured to select a first point-in-time value, which indicates when to begin moving a data image from a first data storage medium to a second storage medium. The point-in-time value corresponds to a calendar date and an hour or hours of the day. The backup server is configured to continue selecting a respective point-in-time value for each data storage medium within a tiered storage hierarchy in order to define the lifecycle policy. The backup server may be further configured to delete a copy of the data image on a source data storage medium when completion of a move of the data image to a destination data storage medium is detected. Further, the backup server may detect scheduling conflicts between two or more lifecycle policies.

1. A method for defining a lifecycle policy for each of one or more data images, the method comprising:
selecting a data image stored on a first data storage medium for definition of a first lifecycle, wherein the first lifecycle includes moving the data image from the first data storage medium to a second data storage medium as part of a backup operation; presenting to the user, in a graphical user interface, one or more time windows of availability for moving the data image during a duplication operation, wherein the one or more time windows of availability are determined to not overlap a time window for the backup operation by more than a predetermined threshold; defining said first lifecycle, wherein said defining comprises:
identifying a first point-in-time value which indicates both (i) when to automatically initiate movement of the data image from the first data storage medium to a the second data storage medium and (ii) when to automatically delete the data image on the first data storage medium at least after movement of the data image is completed; andidentifying a second point-in-time value which indicates when to allow initial movement of the data image from the second data storage medium to a third data storage medium; storing data corresponding to said first lifecycle, wherein said data comprises data which identifies the data image, the first point-in-time value, the second point-in-time value, the first data storage medium, and the second data storage medium.
