1. A computer-implemented method, executed on a computer, comprising:
- selecting at least one object of information, whereinthe at least one object of information is in an archive;
determining a source location for the at least one object of information by accessing metadata, using the computer, whereinthe metadata is related to the at least one object of information,an original placeholder for the at least one object of information had been created and placed at the source location, when the at least one object of information was migrated into the archive,the original placeholder was a stub file that replaced the contents of the at least one object of information, andthe original placeholder comprised at leastan archive identifier,an item identifier, anda checksum; and
recreating a placeholder for the at least one object of information, using the computer, whereinthe placeholder is recreated at the source location, andthe placeholder is recreated using the metadata.

1. A computer-implemented method, executed on a computer, comprising:
-
selecting at least one object of information, wherein the at least one object of information is in an archive; determining a source location for the at least one object of information by accessing metadata, using the computer, wherein the metadata is related to the at least one object of information, an original placeholder for the at least one object of information had been created and placed at the source location, when the at least one object of information was migrated into the archive, the original placeholder was a stub file that replaced the contents of the at least one object of information, and the original placeholder comprised at least an archive identifier, an item identifier, and a checksum; and recreating a placeholder for the at least one object of information, using the computer, wherein the placeholder is recreated at the source location, and the placeholder is recreated using the metadata. - View Dependent Claims (2, 3, 4, 5, 6)

7. A computer system comprising:
-
a processor; a computer-readable medium, coupled to said processor; and instructions, encoded in said computer-readable medium, for recreating a placeholder for an archived object of information and configured to cause said processor to store at least one object of information, wherein the at least one object of information is configured to be selected for processing, determine a source location for the at least one object of information by accessing metadata, wherein the metadata is related to the at least one object of information, an original placeholder for the at least one object of information had been created and placed at the source location, when the at least one object of information was migrated into the archive, the original placeholder was a stub file that replaced the contents of the at least one object of information, and the original placeholder comprised at least an archive identifier, an item identifier, and a checksum, and recreate a placeholder for the at least one object of information, wherein the placeholder is recreated at the source location, and the instructions configured to cause said processor to recreate the placeholder are configured to use the metadata, and the at least one object of information. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus comprising:
-
an archive, wherein the archive is located in a first computer, and the archive is configured to store at least one object of information that is selected for processing; and a placeholder recreation module, wherein the placeholder recreation module is located in a second computer, the first computer and second computer are coupled by a communications network, and the placeholder recreation module is configured to determine a source location for the at least one object of information by accessing metadata, wherein the metadata is related to the at least one object of information, an original placeholder for the at least one object of information had been created and placed at the source location, when the at least one object of information was migrated into the archive, the original placeholder was a stub file that replaced the contents of the at least one object of information, and the original placeholder comprised at least
an archive identifier,
an item identifier, and
a checksum, andrecreate a placeholder for the at least one object of information, the placeholder is recreated at the source location, and the placeholder recreation module is configured to recreate the placeholder using the metadata, and the at least one object of information.

14. A non-transitory computer-readable medium containing instructions that, when executed by a processor, cause the processor to perform a method comprising:
-
selecting at least one object of information, wherein the at least one object of information is in an archive; determining a source location for the at least one object of information by accessing metadata, wherein the metadata is related to the at least one object of information, an original placeholder for the at least one object of information had been created and placed at the source location, when the at least one object of information was migrated into the archive, the original placeholder was a stub file that replaced the contents of the at least one object of information, and the original placeholder comprised at least an archive identifier, an item identifier, and a checksum; and recreating a placeholder for the at least one object of information, wherein the placeholder is recreated at the source location, and the placeholder is recreated using the metadata, the original placeholder is created when an object of information is migrated into the archive.
