Hi Experts, need some assistance in finding a good solution for offsite backup. Basically i work for a company that has sensitive information and management does not want it in the cloud. We have a data center which we can use to store the offsite data. We have about 6 locations that have data that needs to be backed up offsite. We currently use rscync and Buffalo NAS's which seems to need to be babied sometimes and is not very flexible (adjust bandwidth different hours etc). We don't have to worry about bandwidth at the data center but bandwidth is limited at remote locations so some throttling would be nice. At each location we may have about 100-200 gigs of data and would want multiple copies so figure about 1 tb for each location or more.
I am wondering what is best solution? BDR solutions out there seem to want to offsite to their data centers which we do not want to do. HP i think has some NAS's that would work but from just some pricing i have seen seems a bit excessive.
I have thought about getting some DELL servers with like 8 drives and throwing FreeNAS or OpenFiler on. That way i can rsync and i believe would be flexible (have not tried this and am curious how well throttling if available would work, could also use to store VM's and make a SAN out of it). Problem with is the lack of support on the NAS side. We are small so don't have a lot of staff to baby things a long which it seems backup require frequently :).
