System and method for performing auxiliary storage operations
First Claim
1. A method which, when executed on a computer, stores data in a tiered storage system, the method comprising:
- accessing a storage policy associated with a tiered data storage system, wherein the storage policy defines a timing storage policy for copying source data from a data source to at least two storage media destinations in the tiered data storage system;
dividing the source data into a plurality of portions, and assigning a plurality of headers to the plurality of portions by one or more media management components, wherein one or more of the headers comprises time information, the time information based on the timing storage policy, wherein the one or more media management components access and read the time information to determine a time to perform one or more storage operations;
copying with the one or more media management components the plurality of portions, according to the time information in said headers, to a first storage media destination to produce the first auxiliary copy of the source data at a first storage media destination; and
copying with the one or more media management components the plurality of portions according to said headers from the first auxiliary copy to the second storage media destination to produce a second auxiliary copy of the source data at a second storage media destination.

Abstract
Systems and methods for protecting data in a tiered storage system are provided. The storage system comprises a management server, a media management component connected to the management server, a plurality of storage media connected to the media management component, and a data source connected to the media management component. Source data is copied from a source to a buffer to produce intermediate data. The intermediate data is copied to both a first and second medium to produce a primary and auxiliary copy, respectively. An auxiliary copy may be made from another auxiliary copy. An auxiliary copy may also be made from a primary copy right before the primary copy is pruned.

9. A computer storage system comprising:
-
a storage manager component executing in one or more computer processors to access a storage policy associated with a tiered data storage system, wherein the storage policy defines a timing storage policy for copying source data from a data source to at least two storage media destinations in the tiered data storage system; a plurality of headers associated with a plurality of portions of the source data, wherein one or more of the headers comprises time information associated with the timing storage policy regarding a time to perform one or more storage operations, the time information assigned by one or more media management components; the one or more media management components executing in one or more computer processors that access and read the time information in the headers to determine the time to perform one or more storage operations, and wherein one or more of the media management components directs copying of the plurality of portions, according to the time information in the headers, to the first storage media destination to produce a first auxiliary copy of the source data; and a transfer stream configured to stream one or more portions of the first auxiliary copy to the second storage media destination according to the headers to produce a second auxiliary copy of the source data. - View Dependent Claims (10, 11, 12, 13, 14, 15)
