Backup - Probably not

Very much positive there is not to say:
+ Very cheap
+ Relatively quiet
+ Panels of the brand manufacturer

The negative impressions outweigh unfortunately:
- Unpleasant slow web interface: You should keep a ready to configure valerian. I am a very patient person, but the interface operates like an old Atari.
- 260MB firmware is exaggerated, update works for no apparent reason until the 3rd attempt.
- Wakeup function only works from local PCs with extra software - completely impractical.
- Copy function with USB connected media has never worked, no matter what I've tested. Problem on the net (forums) is not dissolved but known.
- Raid 1 has collapsed after 1 month incomprehensible reasons, only by total formatting again produced. Confidence side, the kind of a raid that indeed intended to provide total security and to protect all the data, of course, the worst case scenario. Never again will I trust the thing to what.
- Boot Sequence Super slow

After the RAID now sporadically repeatedly breaks and access via Ipad only about third-party software is easily possible, the NAS goes back now, I am trying a different brand.
