Backups using appliance in remote branch offices v.s. tapes.  Looking at DXi6700/4000 Quantum

We are currently with 5 branch offices doing tape backups and we're not with IT so getting someone to replace tapes is been unreliable.  I'd like to see about putting an appliance based solution in and I just looked at Quantum DXi4000 and 6700.  Is anyone familiar with this solution and can offer any pro/cons from their experience.   We are also going to look at Data Domain.  I'm not sure if there are others to review, but I'd like to find something others highly recommend and maybe using.

How much data do you have to backup at each site? It looks like the Quantum products all include replication, which is good. How many servers at each site? What is your current backup software, and are you happy with it?

You may want to look at solutions that can do incremental forever backups and send them over the WAN. Look at Unitrends and Dell AppAssure. Depending on the capacity or number of servers, they can be really cost effective. Unitrends in particular has appliances that you can deploy at the branches to perform the backups and they can vault (replicate) to each other. You can also probably deploy a single appliance in your main office and then just do backups over the WAN. They also have virtual appliances if that works better for you.

We have 5 branch sites that combined are about 6TB of data.  I am using backup software now to tape at each site, but I dont have staff to reliably swap these out so I'd like something local for a few weeks of restores and then have a large one in my datacenter holding 30 days and then do a month end to tape we keep for 7 years in a storage facility.

I'm mainly looking at the hardware piece now for the storage.  I think AppAssure is software and I've looked at that, but I need to look at some way to get rid of tape at the branches and was hoping someone was familiar or using Quantum and could offer suggestions on likes/dislikes or any others people are using in their branch offices to replace tape.

I have one domain controller and one file server.  I currently have a couple with SQL and applications but those will go away.

I think that the model of just replacing tape with an intelligent disk backup target while still using legacy backup software is a broken model. It is just a band-aid approach that only marginally improves recoverability. I am also concerned that putting hardware at each branch location doesn't scale well in terms of acquisition costs or manageability.

That said, I have no experience with Quantum DXi. The Spiceworks community has a crazy amount of support for Unitrends, and I think that it is a solution you should consider at the very least.

AppAssure and Unitrends both allow you to get rid of tape at the branch. With either, you can backup to a cheap local server at each location, or a local Unitrends appliance. Offsite replication is free. You can also just cave a central server/appliance doing backups of all of your remote sites, which would cut your hardware costs.

For example, a Dell R320 with 2 TB of high quality NLSAS storage is $2,000. Add in a $1200 (list) AppAssure license and your local branch server is protected. That is $3200 per site, you replace your existing software, and you can replicate everything back to your main office. You can also just license each remote server, and backup everything to a single AppAssure repository in your main office, and you can replicate that again to another server, offsite to the cloud or one of your branch offices.

A central Unitrends appliance, the Recovery-822 lists for $22,995 and can protect up to 9 TB of data. If you wanted a physical appliance at each site, the Recovery-612 lists for 5,995 and can protect up to 1.2 TB. Smaller boxes are cheaper. If you go for their virtual appliance, the license cost is just $995 per physical machine you protect. For five remote servers, that could be $5000 in licensing and then a single VMware or Hyper-V server in the main office with some storage, and you're done.

I didn't mean we'd be using legacy backup software we have looked at a replacement for that and now are looking to see what others are doing for hardware at branch offices or backups at branch offices:
1. Put appliance in
2. Replication
3. Tapes

We are looking at Data Domain and Quantum DXi and I'm wondering if anyone is familiar with these and can offer any pros/cons

I just met with Quantum, and they pointed out that you can deploy the Quantum DXi V1000 at your branches for free if you have or can deploy VMware at your branches. You can purchase support on the DXi v1000. At any rate, it makes sense for a small location where the cost of an appliance doesn't make much sense.
