Storage Checkpoints

Storage Checkpoints are a feature of the VERITAS File System (VxFS) that provide point-in-time images of file system contents. These frozen images of VxFS file systems can be used in a variety of applications such as full and incremental online backups, fast error recovery, and product development testing. Storage Checkpoint replicas of real time databases can also be used for decision support and an assortment of database analyses.
