Using two NAS 1200s in order to backup and protect data

[Burtin_1]

Is it possible to use two NAS 1200s ( 2 gigabit NIC) in order to work as indicated bellow :
1. NAS number 1 = primary NAS viewed from LAN and linked by gigabit LINK to secondary NAS.
2. NAS number 2 = secondary NAS which is not switched on LAN but have a link to NAS number 1.

Every day data from NAS number 1 are backuped to NAS number 2.
NAS number 1 and NAS number 2 aren't in the same room obviously in order to increase fault tolerance.

Does it possible with NAS 1200s or NAS 1000s ?
If yes what is the real difference between these two NAS equipment.

Best regards

I don't understand the french comments in the attachment, but the idea sounds reasonable, provided that each NAS box has enough disk space.

You can even do a 'real-time' replication using 'HP OpenView Storage Mirroring'
