So, on Sunday I got to turn on my computer and listen to the lovely sound of one of my two hard drives, which run in a raid 0, clicking away. Luckily, though I don't back up very often, the majority of my information was saved, and I only lost 1 or two more important items (including the start of my cp contest map), all of which can be rebuilt with just a little bit of effort. Therefore, at this point in time, I have a unique opportunity that I did not before, in regards to how best to back up my data. You see, my hard drive was under warranty, so it is getting replaced. While considering alternatives (upgrade, etc), I discovered that the same model drive is available, and at about $20 less than a year ago. This means that I could purchase 2 additional hard drives (for a total of 4) and try a raid 10 setup to back up my information. Or I could use an older, 1 TB external (the total size of my internal drives combined) to back things up to, possibly utilizing some back up type software (the external is a WD my book, and it came with something like that, but the trial expired after 30 days). Or I could use the same external and just try and remember to copy/paste as needed, rather than do some fancy automatic backups. Anyways, does anyone have some thoughts on what would ultimately be the best option? Thanks!
