ReadyNAS® Pro vs ReadyNas Ultra Plus ??

as a note: replicate only works with x86 devices, it won't work with nv+/duo/other sparc devices
also each device needs a license

yoh-da thanks for the calrification!

yoh-da/Tekno - If I can not leverage replicate, does the pro have the ability to snap it's volumes and then land them on the NV?

Sure, there's a comprehensive backup support straight from the ReadyNAS to do this.

Can this be done through the frontview gui, or do I need additional software? I looked up snapshot info under the pro documentation. It didn't describe how to designate a remote nas as a snap target. Could you point me in the direction of the doc's spell out how to do this?

Thanks again for the help and the patience.

I think you are misunderstanding what the Frontview snapshot feature is for. You take the snapshot on the Pro and then backup the snapshot to the NV. The Pro has a single snapshot that can be active at any one time. If the snapshot space runs out it will be invalidated. To create a new snapshot you have to delete the old one (you can schedule snapshot creation).

Maybe I am confusing it a bit. I understand that frontview will take the snap shot. I assume the snaps are done on a volume level and not the entire nas device.
Without running a back up job, can frontview land the newly created snap on the NV? If I can not designate where I want the snap to live, then I assume the snap will live on the pro in some type of snap cache. To get this snap over to the NV, then I would have to run a backup job. What it the software that is running the back up job? Is it native to frontview or will it require a license? Most b/u software that I am familiar with requires the loading of an agent, which can't be done in this case (unless a addon for the specific software has been written i.e. Symantec)


Thanks for helping me out here. I want to be sure that I understand the architecture for protecting my environment and that it will work before I sign the check :?

snapshot is created at the volume level and you must reserve the snapshot space when you first factory initialize your device. Currently there is no way to adjust the snapshot size afterwards.

I think the default is either 5 or 10 gigs.

You want to have a snapshot size that is bigger than the amount of data you expect to change.

In other words, if you expect more than 10 gigs of data to change in between snapshots, you would want to reserve a larger snapshot space.

Once a snapshot is taken, a ready only sharename-snap folder will be created, this is the 'source' for your backup. The destination can be any supported device or server/service (ie you backup the snap to your nv+ via rsync).

snapshots are only supported on 'business' devices, so you need a nvx business or pro business (not a pioneer or ultra model).

you don't need a separate license for any of this.

if you had TWO pro's, you could buy the licence for readynas replicate which is a separate product/addon but essentially makes it very easy to create and manage backup jobs between remote readynas devices, and uses a process similar to the above, making its own snapshots and sending them to a remote readynas.

Perfect. Thanks for taking the time to explain it to me.

I already have drives. Any chance I can pay to upgrade to the software-set of the Pro from the Ultra 6? Really just looking to add teaming/LACP...

nope.

there is a teaming addon, but I do not know if it works on the newer models/raidiator versions. I beleive S-P was going to look into verifying compatibility.

I have a pro business using LACP, and honestly it doesn't really improve the speed anything noticible.
