I am sure this has been discussed before and I did make an attempt to search the forum first before opening a new topic, I got to page 10 out of 88, thought that was not a bad attempt. Basically I want to hear some feedback about Data Domains from other customers, particular in the deployment strategy of the DD's. We use them in our organization, and they are great, but I do question whether we are using them correctly or the best way that we can.
First off, I want to chat about using DD's are a first tier storage repository? Currently our backup jobs are going to the DataDomain, then do a backup copy job straight back to themselves for GFS. While I see this is a perfectly OK way to use them, performance for the Copy job and restores are not amazing. Should we want to improve our RTO's we should be looking at other storage to achieve this?
I saw a comment from Gostev somewhere about the three points of storage, Capacity, Performance and Cost. You have to pick 2 out of the three attributes for your repository, which means a DD should rather be used a second tier, retention based Storage rather than primary storage for higher RTO's?
The second point I have read somewhere is about the recommendation is not to use Storage Replication for the Data Domains, but rather use backup Copy jobs to the second unit? Is this really the case? I have been wondering about storage replication for sometime, are others doing Backup Copys over Storage Replication?
I realize these are more like statements, but I would appreciate opinions on the matter. Have others had the same setup and moved to a more efficient setup? What sort of improvements have they experienced?
Thanks in advance
