US 2015/0149415 A1 · Rollback Mechanism for Linear Tape File Systems

Abstract

A mechanism is provided for restoring a file recorded on a storage medium to a previous version of the file. At least two different versions of a file recorded on the storage medium are presented to a user via a graphical user interface, where the at least two different versions of the file are identified from at least two different indexes recorded on the storage medium. Responsive to a selection of the previous version of the file from the at least two different versions of the file, the file is restored to the previous version of the file by recording a new index on the storage medium for the file that matches an index of the file associated with the previous version of the file.

Dependent claims

A method, in a data processing system, for restoring a file recorded on a storage medium to a previous version of the file, the method comprising:

presenting at least two different versions of a file recorded on the storage medium to a user via a graphical user interface, wherein the at least two different versions of the file are identified from at least two different indexes recorded on the storage medium;
and
responsive to a selection of the previous version of the file from the at least two different versions of the file, restoring the file to the previous version of the file by recording a new index on the storage medium for the file that matches an index of the file associated with the previous version of the file.

A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:

present at least two different versions of a file recorded on the storage medium to a user via a graphical user interface, wherein the at least two different versions of the file are identified from at least two different indexes recorded on the storage medium;
and
responsive to a selection of the previous version of the file from the at least two different versions of the file, restore the file to the previous version of the file by recording a new index on the storage medium for the file that matches an index of the file associated with the previous version of the file.

An apparatus comprising:

a processor;
and
a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
present at least two different versions of a file recorded on the storage medium to a user via a graphical user interface, wherein the at least two different versions of the file are identified from at least two different indexes recorded on the storage medium;
and
responsive to a selection of the previous version of the file from the at least two different versions of the file, restore the file to the previous version of the file by recording a new index on the storage medium for the file that matches an index of the file associated with the previous version of the file.
