Rollback Mechanism for Linear Tape File Systems |
| 摘要 |
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. |
