| 20080201391 | Methods and apparatus for adjusting a journal area for continuous data protection - In a storage system implementing journaling for data backup and restore, users are able to easily determine information regarding amounts journal data generated over specified periods of time. Flexible and automatic adjustment of the journal area is enabled by providing the user with the information on the relationships between the amounts of journal data generated over periods of time. Also dynamic allocation of storage capacity from free space may be applied to the journal volume on an as-needed basis, and may be used to minimize the size of the journal volume when certain journal entries are determined to be no longer needed. Thus, users are able to determine an appropriate size of a journal area in accordance with requirements for predetermined preservation periods for backup data. Thereby, management of the journal area is simplified and the costs to manage the journal area are reduced. | 08-21-2008 |
