Which NAS for off-site mirroring of on-site NAS?

[Wolters]

Hi,

We have a small office with five people on the same LAN and would like to buy an NAS for mainly backup and file serving purpose. At the same time it would be great to buy a second unit that after an initial full backup of the first NAS at the office could be taken off-site and function as a mirror of the "office-NAS". This means that we are looking for an NAS that in a robust and secure way copy the files that has changed on the office-NAS and send them to the off-site-NAS automatically. Should we look for an NAS with rsync over SSH capabilities? Or are there other secure protocolls that we should look for?

So the idea is that in case of theft or fire at the office, we simply take the off-site-NAS to the office and we will be up and running in almost no time. As the NAS also will be running an Access dababase back-end, I guess that performance is somewhat important too???

We will not use the NAS for any mediastreaming, etc, but the possibility to get to the shares over the internet in a secure manner, might be interesting.

Any thoughts and recommendations of a robust and user friendly NAS would be most welcome!

Regards,

Dag

Many NASes support rsync / SSH. But when going from LAN to LAN, you'll need either a fixed WAN IP or a dynamic DNS service.

Synology, QNAP and NETGEAR NASes will all support what you want to do. Keep in mind that using SSH will cut throughput significantly. Not a real problem if you're doing incremental backups, however.
