storage solutions & backups
Posted on 2009-03-29
I'm getting into video (via new Panasonic HD camcorder) and am starting to rack up the Gigs in terms of movie files.
Also, more generally, at work my office disk will soon outgrow its 250Gb size, which is a RAID1 setup.
I'm looking to create some sort of BACKUP and REDUNDANCY functionality for the home setup (and enhance what I have with the work setup).
I've read the basics of RAID on wikipedia, so now I know that RAID1 is mirrored, but with no error-correction, so redundancy is built in.
But if we start with the home/camcorder situation:
I see that you can buy 1TB external drives now for less than £100. I'm not sure if you can get these set up as RAID(n), but if so I'm assuming they will be very expensive.
Maybe for the home/camcorder PC its best to just get 2x 1TB externals and plug em both in, have one be the working disc, and one be the backup?
How long will it take to copy 1TB from external disc #1 to external disc #2 (both plugged into USB ports) ?
Also to delete 1TB from disc #2?
(or is there a software solution that would turn disc#2 into a backup, so you didn't have to manually delete and copy - I guess so....?)
..and would there be a performance decrease by going thru' the software solution
