I had always assumed that Raid1 was a good way to keep things backed up. I have something like 250GB of music, 300+GB of video, and 20+ GB of photos that I keep on various Raid1 sets. I thought that was decent protection, but a few offhand comments made on various boards have got me wondering. Backing up to removable media isn't an option - I don't have them time to do DVD backups of even the photo data at 20GB, never mind the music/video data. I need something automatic or I will no doubt forget to do the backups. I do realize that if I write corrupted data, then corrupted data will get mirrored. Is something like that a big worry? Anyone have any thoughts or ideas to help me out here?
