I have a ton of data that I've been keeping 2 complete copies of between my Desktop and Laptop for a couple years now; I figure its about time to buy some more drives and make sure I don't lose any of it due to drive failure and whatnot.
At first I was looking to RAID, but then I started to wonder if there are good purely software solutions to use for redundancy on a PC containing multiple drives. In my mind I picture having one empty drive with a capacity as large as or larger than each other drive; to hold the re-construction of a possible failed drive etc.
Is there anything reliable out there for a purpose like this? Also what is the drive/hardware setup recommended for such a task.
Edit: To clarify, I'm not against RAID and I would be willing to just use Backup solutions, I'm mostly curious to see what other options are out there for the situation I described. Thanks.
