Is this thing any good? Seems like a cheap way to make an array for rotating backups.
i would use stand alone external HDD,connected via USB or better yet-specifically for backups-connected to USB on separate PC on network(some old PC) that is off,when you not making any backups.
then i would use something like acronis to create full and then incremental backups,rather than rotating.
this thing is good IMO for everything, EXCEPT backups. fast load,back testing,working with databases etc..
