What tape seeding is Tape seeding is an SMTape functionality that helps you initialize a destination FlexVol volume in a data protection mirror relationship.
Performing tape seeding using SMTape
Using SMTape, cluster administrators can perform tape seeding to initialize a destination FlexVol volume in a data protection mirror relationship. The time taken to initialize this destination volume over a low bandwidth connection using SMTape is faster when compared to using the snapmirror initialize command.
Scalability limits for SMTape backup and restore sessions
While performing SMTape backup and restore operations through NDMP or CLI (tape seeding), you must be aware of the maximum number of SMTape backup and restore sessions that can be performed simultaneously on storage systems with different system memory capacities. This maximum number depends on the system memory of a storage system.
Manually updating data protection mirror copies on destination volumes
You can schedule updates to data protection mirror copies for destination FlexVol volumes or Infinite Volumes, or you can manually update a data protection mirror copy to transfer Snapshot copies between the source and destination volume. However, for Infinite Volumes, you cannot choose which Snapshot copies to transfer.
Deleting a mirror copy
You can delete a mirror relationship and the destination FlexVol volume or Infinite Volume if you no longer want the mirror copy.
Considerations when breaking SnapMirror relationships
You might break a SnapMirror relationship when a disaster impacts the source volume so that you can temporarily serve data from the destination volume. There are some considerations you should understand before breaking a SnapMirror relationship so that you can avoid issues.
Testing database applications
You can use data protection mirror relationships to create a copy of database data on which to test software applications that run on a database, to avoid the possibility of changing or corrupting the database.
