Point-in-time copy solutions supported by SFDB tools
Storage Foundation for Databases (SFDB) tools provide a database-specific command line to create point-in-time copies of your DB2 database. SFDB tools use the underlying features of Storage Foundation to perform these operations.. For ease of use, the SFDB command line enables you to perform the point-in-time copy operations on the DB2 database with fewer steps. Also, the SFDB command line enables you to perform functions specific to DB2 databases.
Table: Comparison of Point-in-time Copy Solutions provides a comparison of the point-in-time copy solutions supported by SFDB tools.
Table: Comparison of Point-in-time Copy Solutions
FlashSnap | Database Storage Checkpoints | |
---|---|---|
Underlying technology | Volume snapshots (third-mirror break-off snapshots) | File system checkpoints |
Possibility of off-host processing | Yes | Yes (requires Cluster File System) |
Additional storage requirements | Additional mirror plexes are required. Plexes are full copies of the original data. | Minimal (uses copy-on-write) |
Performance impact after taking the point-in-time copy | None | Copy-on-write penalty |
Support for multiple clones from a single point-in-time copy | No. However, different mirrors with different snapshots can be used to create multiple clones. | Yes |
Supported snapshot modes | Online, Offline | Online, Offline |
