Hello,
I have 2 TS-473A NAS, and I need them to be synchronised at all times. The idea is that if one of them breaks down, the other one can make the content available on the network. Is there a cluster-type configuration that can be done linking the two NAS?
Another question, can this be configured automatically? In other words, if the primary NAS crashes, the secondary NAS can make the content available without changing the settings (IP, name, etc.).
Best Regards
2 NAS Clone (Cluster)

No there is no cluster functionality available. Disaster recovery need to be manually thought out and executed.
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!
A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.
All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!

Re: 2 NAS Clone (Cluster)
Look at a proper full cluster capable system if that is what you need. Be prepared to pay a fair amount of money depending on the service level you need. This isn't as simplle as installing an app to do it properly.
You could probably put together a home grown system to do something similar, but not as automatic or efficient. You could setup your own DNS service that included failover support (I've worked with commercial versions in the past but have no idea what is available "free" or in recent years). You could then replicate the data portion use HBS3 active sync or some other tool. The DNS failover would, in theory, monitor system availability. If the primary system goes offline, then the requests are routed to the secondary. I wouldn't use this approach for loadbalancing though, that really requires a commercial level product. The DNS failover would only work at the network level (i.e. being able to ping the system), not at the service level.
