Replicate or synchronize folders between two NAS over VPN
We have a remote office where a NAS (Buffalo TeraStation III, btw) is being used to store data.
We would like to replicate certain important folders to main office for backup.
I think the ideal solution for me would be to setup another NAS in main office and let them sync by themselves, because this solution does not need any computers to be invovled, it is a matter between two NAS only.
Have you ever used or seen or heard of a NAS like this? Is it reliable?
Thanks
Jack

I use IBM technology, SAN to SAN hardware replication synchronous based on metro mirror to replicate Data 1TB DB over Darkfiber distance=5Km with zero lost data between 2 sites (SiteA+SiteB).

Metro Mirror is generally considered a campus-level solution, where the systems are located in fairly close proximity, such as within the same city. However, the distance supported will vary based on the write intensity of the application and the network being used. In general, with adequate resources, most customers find up to a 50-kilometer distance acceptable with some customers implementing up to a 300-kilometer distance.

I have used a variety of solutions but I like the solution for block level replication that EMC and NETapp have the best. There is a pretty hefty price tag that come with these solutions. Unfortunately I can't remember the names of the technologies off the top of my head and I am no longer with the companies that I implemented them for or I would check for you.
There are some of software solutions. I have actually found that the MS DFS-R in windows 2003 r2 and windows 2008 work pretty well and allow you to throttle bandwidth and do imcremental synchronizations. It also a low cost solution which make it attractive.
I have also used EMC Replistor which has some nice features but lacks the ability to monitoring the software well and I not completely sure they are selling the solution any longer.
There are a number of different ways to accomplish this and everyone will have their favorite. If you want any more info on any that I have mentioned let me know.

Thanks for the details. The solution looks very pricey though. I would look into that when we have more data to replicate. At this moment, the data we are looking to replicate is about 100GB.

Do I have to setup a Windows Server on the remote office? The remote office does not have a server at this moment. There are less than 10 Windows XPs and 1 NAS.
The main office has a SBS2003 R2 server and a Windows 2003 R2 Terminal Server

For DFS-R you do have to have a server on both sides. If you are replication or synching files you have to put something at the remote office correct?
ASKER
Yes, Wlllettmeister, it makes sense.
When using DFS-R, does the data that needs to be replicated have to be on the server itself or can be on a NAS?
Thanks

Thanks Willettmeister, i will look into DFS for sure.

I did not make myself clear. I am looking for a tested working solution which is able to do NAS to NAS backup via VPN. It does not have to be a Buffalo product.
"In general I prefer doing storage to storage replication over synchronization of files via software connected to the storage device. " What solution do you use to achieve this?
Thanks
