50% smaller backups !

A unique new technology called Infinite Reverse Incremental Backup enables Ocster Backup Pro 8 to create much smaller image backups than other backup solutions. The total size of the backup data is reduced by approximately 50 %!
More information

Normal incremental systems can only create a limited number of incremental backups before they need to add a new full backup. Otherwise their backup quality decreases and restore times increase too much. They also cannot delete old backups without either creating a new full backup or performing time-consuming data merge operations.

The infinite reverse incremental system used by Ocster Backup Pro 8 does all of this much better. Only a single full backup will ever be created. Because of the reverse incremental setup, old backups can easily be deleted at any time and the data safety and backup quality do not decrease over time.

Since only a single full backup is stored (compared to the two or more full backups needed by other systems), the overall backup data size is much smaller.
