Overall Satisfaction with Data Domain
Data Domain is currently being used to store our database backups. We utilize the NFS and SMB functionality to provide storage locations for our database administrators to perform their daily backups including logs. We also use MTree replication to replicate to a secondary site for offsite disaster recovery.
Pros
- MTree replication to another Data Domain system. The Data Domain performs the replication every 15 minutes, so our offsite data is never more than 15 minutes out of sync with production.
- DDBoost provides a faster way to back up our data.
- Data encryption at rest. This allows us to protect our database data.
Cons
- Depending on the model of Data Domain, there is a limit to the number of NFS/SMB threads that can run concurrently. When this limit is reached, the system is slow to respond to client requests.
- Data Domain support is very slow to turn out new features and bug fixes in their code.
- OS upgrades are very slow and disruptive.
- Data Domain says 20+ hours per week when compared to using a tape library. Once the unit is configured it basically takes care of itself.
- With MTree replication we no longer need to send tapes to an offsite storage facility.
- Having a second data domain at our DR site allows us to perform recoveries from any of our replicated backups. We do not have to order and wait for tapes to arrive.
