Abstract
A system and method are provided for verifying data copies and reverifying the copies over the life span of media according to a verification policy. Characteristics of media and use of media are tracked to provide metrics which may be used to dynamically reevaluate and reassign verification policies to optimize media usage. Copies that fail verification operations may be repaired by repeating a storage operation for recent copies or by substituting a close temporal copy of the failed copy.
Claims11
A method for reverifying data, the method comprising:
- in accordance with a verification policy, identifying a media item and initiating a verification operation;
- and
- in association with an outcome of the verification operation, tracking at least one storage characteristic of the media item.
A method for repairing reverified data, the method comprising:
- initiating a verification operation for a data copy, according to a verification policy;
- if the data copy fails the verification operation, repairing the data copy, wherein repairing the data copy comprises identifying a close temporal copy, and updating the data copy with the close temporal copy.
A method for forecasting media usage, the method comprising:
- receiving at least one storage characteristic of a first media item among a plurality of media items;
- receiving a verification policy for the first media item;
- initiating a verification operation for the first media item according to the verification policy;
- tracking an outcome of the verification operation;
- calculating a metric based on the outcome and the at least one storage characteristic;
- and
- based on the metric, evaluating the verification policy.
