Abstract:
1. A method for reverifying data, the method comprising: receiving an indication to perform a first storage operation; identifying a plurality of files stored on a first media device that are associated with the first storage operation; organizing the plurality of files with one or more computer processors into at least a first data package of first data with a header, wherein the header of the first data package comprises first metadata, the first metadata comprising at least a first archive file identifier and a first sequence number; performing the first storage operation on the first data stored on the first media device by transferring the first data package to a second media device with lower performance than the first media device to generate second data wherein the second data comprises at least a second data package with a second header, wherein the second header comprises second metadata comprising at least a second archive file identifier and a second sequence number; verifying that the second data is an accurate copy of the first data by comparing the first metadata of the first data with second metadata associated with the second data; updating a verification table to indicate results of the verification of the second data; accessing a verification policy indicating a first reverification time period associated with reverifying the second data stored on the second media device, the first reverification time period being based at least on a life expectancy of the second media device; initiating at least one reverification operation of the second data according to the first reverification time period; accessing a usage history of the second media device, wherein the usage history comprises at least a number of storage operations performed on the second media data and, when the number of storage operations exceed exceeds a threshold amount, establishing a second reverification time period for the second data stored on the second media device, the second reverification time period being more frequent than the first reverification time period; and initiating at least one reverification operation of the second data according to the second reverification time period.
