NetApp SnapMirroring
- SnapMirroring Technology
- Replicates file system from one NetApp Storage to another
- Two filers can be at different geographical location
- Replication can be Synchronous, Asynchronous or Mixed of both
- Files/Data is replicated using NetApp Snapshots
- Synchronous Mirroring replicates data on change basis
- Asynchronous Mirroring replicates data on fixed intervals
- As and when any change is spotted at the source filer it is immediately replicated across the target filer.- The changes are scanned at the block level
- Once initialization is complete, replication events thereafter copy only changed blocks from the source volume to thetarget volume
- A snapshot taken at fixed interval is compared to the previous snapshot and the difference is replicated across thetarget filer
- Mirroring is intialized by copying the entire Source Vol to Target Vol
- Replication can be made at Volume or Qtree level

- SnapMirroring Scope In OBSS
- Disaster Recovery Solution
- Data Replication
- Load Balancing
- Test & Development Environment
- Traditional Backups (copying datafiles) can be replaced completely.- Backups through SnapMirroring are quick, flexible and neglegible resource consuming.- Multiple Backups on different filers (same or different locations) can be maintained.- Immediate availability of backups, Restore & Recovery process is in seconds.
- Multiple copies of the data can be maintained with neglegible impact on the performance- Data can be maintained across different filers at the same or different locations- Specific data (partial or selective data) can also be maintained across different filers
- Specific data can be replicated across different filer to be accessed by separate server
- Standby Database- Standby database can be maintained by replicating only Archived Logs across the filer linked to the StandbyDatabase
- SnapMirroring is best suitable for maintaining the Test & Development environment- Refreshing the test or development environment is a simple & matter of few seconds
