My company is an IBM partner.

We deal with this solution more on the service-side and in terms of offering up service parts. We do data protection too and handle recovery services for clients. 

We use the on-premises solution as the cloud is not allowed in China.

I'd recommend the solution. However, it depends on the system a company has. It's not ideal for every type of company.

I'd rate the solution seven out of ten. The system overall could use some improvements here and there.

I would recommend Disaster Recovery Services to other users and rate it nine out of ten.
