This article provides frequently asked questions (FAQs) and solutions about how to identify and correct issues that might occur when using Data Domain system MTree replication.

Below are a few frequently asked questions (FAQs) and solutions about identifying and correcting issues that may occur when using Data Domain system MTree replication:

1. Data Domain: Replication Matrix and Supported Topologies
2. Can MTree replication be used for Boost storage units?
3. Does MTree replication support multistreaming?
4. Data Domain - MTree replication support of low-bandwidth optimization
5. Does MTree replication support encrypted replication?
6. How many MTree replication contexts are supported on each system?
7. Can MTree replication for the "backup" MTree be set up?
8. How to setup a new MTree replication context using the CLI?
9. How does MTree replication work?
10. Is it possible to tune the frequency of the system-generated snapshots to trigger frequent replication of the MTree?
11. How many Snapshots can be created on any MTree?
12. If a MTree already has 750 Snapshots, then will MTree replication no longer work?
13. If there is a MTree with user-created snapshots, and then MTree replication is set up, are the existing snapshots on the MTree replicated to the destination?
14. Can the system-generated snapshots be viewed?
15. Must the user clean up the system-generated snapshots?
16. Do system-generated snapshots consume space until GC is run?
17. Does MTree replication delete user-created snapshots?
18. If replication is interrupted for a long duration due to network outage or issues with the destination Data Domain system, does MTree replication create many system-generated snapshots on the source?
19. What is the maximum number of system-generated snapshots that are created on each MTree?
20. Can snapshots on the source and destination of the MTree replication context be created?
21. Does MTree replication replicate the retention period for a snapshot to the destination?
22. Can separate retention periods on the source and destination be configured?
23. Do MTree snapshots expire simultaneously on the source and destination of a MTree replication context?
24. The system-generated snapshots show a retention period of 1 year at the destination. Does this mean that this snapshot is retained on the destination for one year?
25. Why are there appended digits to the replicated MTree snapshot names?
26. What is the process for initializing a MTree replication context?
27. Is there any impact on Ingest when initializing a MTree replication context?
