Backing up data between 2 NAS units?

Would not recommend you use the Duo for this.

I would recommend two Pro 2 (RNDP2000) units using ReadyNAS Replicate (http://www.readynas.com/replicate) or Rsync over SSH.

Whilst you could use the Duo for Rsync this is not secure. So you'd either have to setup your VPN or use a community add-on to do Rsync over SSH (performance may be unbearably slow).

Thanks, but the cost of the RNDP2000 is 3 times as much, not too worried about security, so will the replicate software work nevertheless? data transfer is minimal about 300MB daily

Replicate only runs on x86 NAS (e.g. Ultra, Pro). You could use that with the Ultra 2. Do note that after the free trial you need to purchase a license for each NAS if you wish to continue to use it.

I would recommend that if you can stretch your budget to getting the Ultra.

Ok, if I go for the RNDU2000-100AUS, will replicate work ok? this unit is an extra $150, not for me but a customer that has a budget. I try to tell them that data is important, would have done just one unit as RAID1 but if there was a flood or fire they will have a backup at another location hence the 2 units
cheers

Provided you don't need the snapshot feature then it will be fine.

Snapshot feature? also what does the license cost for each unit running replicate?

Snapshot feature basically allows you to backup your data frozen at a point in time.

License cost for Replicate is a bit over $200 per unit.

In laymen terms why would I need the snapshot feature?

It allows you to backup a NAS folder even if a user is changing some files in the folder. (The changes are not backed up). So it maintains availability while the backup is in progress.

ok Thanks, the backup will be done at midnight so no one will be using any files, so I don't really need that feature do I?
cheers
