By intelligently identifying and backing up only data which has changed and minimizing server impact, Continuous Data Protection technology offers a smart and scalable backup methodology that can help protect data.
Continuous Data Protection (CDP) provides a high-performance, granular backup solution and supports storing large amounts of data, while minimizing impact on server performance. By eliminating the heavy disk usage that’s become synonymous with traditional data backups, CDP offers an innovative and smart alternative to existing legacy data backup methods and technologies.
By focusing on block-level storage, Continuous Data Protection can be used to restore previously captured data to another storage device, effectively replicating the structure and contents to the new device. The virtual filesystem inside the CDP disk image can be restored to its original location or to an alternate system. It’s an innovative approach to backup that relieves the considerable burdens associated with enterprise-level data management.
Block-Level Backup: Smart and Efficient
Block-level backups operate below the file system and examine blocks of data on the disk, with no regard for the files with which those blocks are associated. When data in a given block changes, only that block is included in the next incremental or differential backup (rather than the whole file). This makes the backup process much faster than file-level backup, reduces wear on the disk drive, and takes up less network bandwidth.
