Reviews (1-6 of 6)
- The deduplication is fantastic. We are currently seeing total compression factors in the mid to upper 50s.
- The platform is very reliable and stable.
- It backs up a wide variety of enterprise apps (e.g. legacy applications, UNIX, iSeries, open systems etc) or your primary storage.
- It can be expensive to implement, especially when used in conjunction with other applications/hardware such as Avamar.
- The TCO can be high, especially when it needs its storage expanded.
- Recovery speeds can be slow (compared to other solutions) for when recovery is time sensitive.
Due to the price point, it may not be well suited for environments that are mostly virtualized with a small data footprint.
- Compresses backups well.
- Very reliable.
- Upgrades could be simpler.
- The sales process could be simpler. We bought 2 nodes for DR, but one was with VxBlock which complicated the process.
- Better reporting.
- High data ingestion rate. For inline dedupe, these devices can ingest a saturated Gigabit Ethernet line, plus a FibreChannel from an AS/400.
- High reliability. In ten years of having at least two units and ingesting 1.5 to 2TB/night of backups, we've replaced maybe three disk drives.
- Scalability. Dedupe ratios are very good (11:1 for us for all data), and the DD2500 models allow addition of disk trays to expand capacity.
- Ease of use. Management interface is good, the free Data Domain Management Center Appliance is even better.
- Dedupe ratios on a per-folder or per-CIFS share basis would be nice, we can only see the ratio per partition (MTree). So it's not possible to see what ratio we get from Tivoli data vs vRanger data, for instance, because they're in the same MTree.
- The VTL option seems inordinately expensive given it's only software. We held off a long time because of the cost, and only went down that road because the IBM iSeries is inherently unable to do a DR recovery from disk only.
- 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.
- 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.
- Cross-site replication.
- Easily maintained, organized and replicated backup schedules and policies.
- Deduplication is amazing, we are seeing in some cases with OS and file 22:1 dedupe.
- VMware integration from a restoration perspective.
- Initial ingestion for data can get bloated at first it would be nice to see a better estimation of what you most likely will see after dedupe and compression completes.
- Better data aging and deletion capabilities, we see periodic bloating with lower retention policies.
- Data Domain is very good at data reduction of database backups (IBM DB2, SAP HANA, Oracle).
- Data Domain is an excellent choice for WAN optimized long distance DR data replication.
- Data Domain is extremely reliable and stable.
- Restore speed could be improved. Restores are much slower than backups.
- It would be nice if there were multi-controller larger capacity configurations.
- Increased large environment remote management functionality would be a welcome addition.
