[MCN-L] NAS HDD
Hello Matthew-- We use NAS units here to back up our digital collection and other vital data in triplicate; it gives us a little over 7 TB of storage. Since the implementation of this system in 2011, we've used a little less than half the capacity. Backups occur daily, weekly, and biweekly among the 3 units. This system works pretty well for us. Good luck. Regards, -- Matt Wheeler, Photography Archives, Penobscot Marine Museum Archives (207) 548-2529 ext. 211

Hi Matthew At the Norman Rockwell Museum I backup exclusively to enormous direct-attached storage (DAS) arrays, but the concept is the same as network-attached storage (NAS) appliances. There are many advantages over tape: - More reliable with no tapes to change (or forget to change!) and no tapes to wear out and fail. - MUCH larger data storage than tape so I do not have to pick-and-choose what to back up. I back up everything. - Entire drive array is periodically swapped for an identical array which is kept off-site in a bank vault. - Instant restore jobs without tape swapping. For hardware, options vary wildly in price. One of the most economical appliances I've found is the Buffalo TeraStation Pro. The TeraStation Pro Quad has (4) 1TB drives. In RAID5, you'd have 3TB of online storage. If you want it even more reliability than RAID5, you can set it for RAID 10 with 2TB of storage. Much larger models are available. This is dirt cheap, under $900. Other models have Windows Storage Server OS if that familiar interface is appealing. http://www.buffalotech.com/products/network-storage/professional-and-business-class-nas/terastation-pro-quad-1 I have gone the bomb-proof route with very large direct-attached storage (DAS) arrays rather than network-attached storage (NAS). I also mirror entire arrays between two buildings. The reason I prefer DAS over NAS is the drastic increase in data throughput. The speed is needed because 24 hours would not be enough time to copy the amount of data from a full backup into a NAS via 1Gbps Ethernet. The bulk of our data is stored on a second array on the same server as the backup array and it simply copies from one array to the other inside the same physical server at 6Gbps SAS. All this high-end stuff was funded by several collection digitization grants which included a budget line for server hardware. I also prefer DAS because I can expand the arrays when needed. I use (2) Dell MD1220 chassis with 24 SAS slots in each. http://www.dell.com/us/business/p/powervault-md1220/fs Frank Kennedy, IT Manager Norman Rockwell Museum 9 Glendale Rd., PO BOX 308 Stockbridge, MA 01262 413-931-2216, fax 413-931-2316 http://www.nrm.org

Hello, Forgive me if this topic has been covered. I am looking for assistance with on-site back-up options (offsite back up is already settled). We are searching for the best way to back-up all crucial data in house, preferably with the piece of hardware stored in our collections space (does anyone know of risks to having an external hard drive or other hardware in the collections space?). We have access to our small office network in our collections space, and I've been investigating something called Network-attached Storage Hard drives. Basically, we might like an external hard drive that can function like a server, providing access over a network of numerous computers. Our PastPerfect Software could back-up to it daily. Is anyone using an NAS HDD for on-site back-up? And, are you happy with it? Thanks!

How much data are you backing up. And what are your time constraints, how much do you want to invest, and do you desire de-duplication to conserve disk growth. Please excuse any misspelling, this message was sent from my Windows Phone.
