JimmyH: So what are people using for large backup sets then?
I have about 9TB on my RAID array at the moment (RAID5 NAS) replicated to USB hard drives. Data seems to grows at 1-2TB a year. Mostly media, so once it hits the NAS it never changes, and about 100GB of data that changes frequently.
Having lost a couple of USB drives over recent years, I'm no longer too keen on USB drives as a backup option, despite using this option at present.
The two options I'm thinking of are 50GB dual-layer blurays (Verbatims can be landed for about $3.50 each = circa $70 per TB), or picking up a second hand LTO-4 tape drive.
That's something I wonder about too. My solution is to never have a set of data larger than the largest hard drive I can buy, and I buy top quality drives and put them into my own enclosures.
I've looked into tape but it's pretty expensive. Blu Ray writes seem to be $150 or so, or US$40 from amazon. Media are around $12 bought from ascent - you obviously want the best quality, but I see you can get them for US$2 for 50GB or US$.50 - $1 for 25GB disks. Not a bad plan actually, all my data is on hard drives, having a second format seems quite sensible.
Anyone got opinions on blu ray reliability, especially over multiple years?
