Help finding a Unix friendly RAID 1 backup
First time poster and a very new Unix user, so I'll just pre-apologize for stupid questions now.

Does anybody know of a good RAID 1 hard drive backup that is Unix friendly? I want to avoid any hardcore programming. Can you recommend both NAS and non-NAS options? I need to do nightly backups from a Unix data server running SAMBA/SWAT that currently has ~300 of 420 GB used split between public and user folders. This is for an office and involves sensitive data so I need a safe and secure option.

This is what I was able to find online that seems to fit what I'm looking for:
Buffalo Technology TeraStation Duo TS-WX2.0TL/R1 2x1 TB 368.98

Synology DiskStation DS211 21002x1 TB550.99

Netgear ReadyNAS Duo 2-Bay RND2210 2x1 TB 393.6
Data Dock II DDQ-2000 2x1 TB 269.95
Do any of the above make sense? From what I can tell, only the Netgear is out of the box Unix friendly; the tech guys at Fantom couldn't tell me whether the data dock II was or not. Can you recommend any of these or other models? I don't really think I need the NAS option and it seems you pay considerably more for that. Should I be looking at an entirely different type of data storage? (Cloud storage is not an option)

In the meantime, while I figure this out, my boss wants me to backup the data asap. I was thinking about getting a consumer grade 500 GB or 1 TB external with an ethernet port and simply manually backing up the data via windows. I was thinking this would provide a good stop gap and, once the RAID 1 is setup, could simply be manually backed up weekly and provide essentially an additional disk to the RAID 1 array.

For this I was looking between these two:
Iomega Home Media 34337 1 TB 99.99
Buffalo LS-CH1.0TL 1 TB 99.99
Any help is greatly appreciated. Thank you.

mfi

MFI(4)							   BSD Kernel Interfaces Manual 						    MFI(4)

NAME

     mfi -- LSI Logic & Dell MegaRAID SAS RAID controller

SYNOPSIS

     mfi* at pci? dev ? function ?

DESCRIPTION

     The mfi driver provides support for the MegaRAID SAS family of RAID controllers, including:

	   -   Dell PERC 5/e, PERC 5/i, PERC 6/e, PERC 6/i
	   -   Intel RAID Controller SRCSAS18E, SRCSAS144E
	   -   LSI Logic MegaRAID SAS 8208ELP, MegaRAID SAS 8208XLP, MegaRAID SAS 8300XLP, MegaRAID SAS 8308ELP, MegaRAID SAS 8344ELP, MegaRAID
	       SAS 8408E, MegaRAID SAS 8480E, MegaRAID SAS 8708ELP, MegaRAID SAS 8888ELP, MegaRAID SAS 8880EM2, MegaRAID SAS 9260-8i
	   -   IBM ServeRAID M1015, ServeRAID M5014

     These controllers support RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50 and RAID 60 using either SAS or SATA II drives.

     Although the controllers are actual RAID controllers, the driver makes them look just like SCSI controllers.  All RAID configuration is done
     through the controllers' BIOSes.

     mfi supports monitoring of the logical disks in the controller through the bioctl(8) and envstat(8) commands.

EVENTS

     The mfi driver is able to send events to powerd(8) if a logical drive in the controller is not online.  The state-changed event will be sent
     to the /etc/powerd/scripts/sensor_drive script when such condition happens.

SEE ALSO

     intro(4), pci(4), scsi(4), sd(4), bioctl(8), envstat(8), powerd(8)

HISTORY

     The mfi driver first appeared in NetBSD 4.0.
