In a multi-platform environment, data backup is performed which stores data from various different systems on several storage devices depending on the importance of the data and the reliability level of the backup storage devices. That is, data marked as important is stored on a backup storage device having a high reliability level and less important data is backed up onto a backup storage device having a lower reliability level. This allows the cost performance of the backup system to be optimized. |
