Mirroring a Hard Drive
I'm moving to university this fall, so I was talking with my dad about getting a UPS. We figure its something that can come later, since I'll probably only have to worry about brownouts during the summer months. He suggested that, to protect my data from hard-drive crashes (caused by surges/brownouts or just mechanical failure) I should just mirror all my data with another hard drive. He's in the IT business and works mostly with Windows 2000 servers, but he was talking about selectively mirroring certain folders, using differently sized hard drives. I thought it was some form of RAID, but apparently it isn't.
I figured Linux should have some type of thing like this, Logical Volume Management springs to mind, although I really have no experience with this.
Anyone doing what I'm talking about? I use LFS
, so where would I get the tools/info for this type of thing?
