Data Domain to ECS

Hi team,

We have been running Data Movement on our DD's 4200 for the last 2 months on MTREE's that were setup to move old backup data to Cloud Tier. While we have moved over 37 TB's so far to our new ECS cloud tier on R1 and R1, the active Tier isn't reflecting the space that is supposed to be moved.

While space has been detiorating for the last few weeks, we are concerned that ECS isn't a suitable solution in freeing up space on Data Domain.

Has anyone had similar issues, or is there anything else we can do to free up more space besides cleaning?

Austin
