What are the minimum supported SnapMirror schedules?
Applies to
- ONTAP 9
- Asynchronous SnapMirror only
Answer
The minimum supported asynchronous SnapMirror schedules (i.e. minimum supported RPO) depend on the type of relationship and volume in-use:
SnapMirror Configuration | Minimum supported RPO |
FlexVol volumes | 5 minutes |
FlexGroup volumes | 30 minutes |
SVM DR for FlexVol volumes | 15 minutes |
SVM DR for FlexGroup volumes | 30 minutes |
Consistency Groups for FlexVols (ONTAP 9.13.1 and later) | 30 minutes |
Note: Schedule update may be skipped when the configured schedule does not meet this minimum RPO requirements.
Additional Information
- SnapMirror Synchronous is available to provide support for zero RPO configurations
- Replication intervals
- SnapMirror for SVM DR
- SVM-DR transfer for FlexGroup volume failed
- FlexGroup data protection minimums
- Protect a consistency group
- Schedule update of SVM DR gets skipped randomly
