What are other people doing for backups these days? I am looking for a solution that is portable, small, and holds at least 500GB. Tapes are starting to wear too fast in dirty environment. Need something that can be taken off-site or stored in a vault when not in use.
I've switched over to a dual system. External drives which I rotate off site periodically and a cloud system using Rackspace Cloud Files. I wrote about it on my blog recently.
Greg - I'm in the same target area of space and will be switching to external hard drives in 2010. I looked at it from a alot of angles. Cloud / online is too bandwidth hungry and costly for my volumes and retentions. I don't use enough tapes to justify the cost of keeping up and LTO loader. When looking at external drives and considering their reliability, speed, non dependence on a tape drive, cost, environmental sensitivity, and physical space consumption I could not find much reason not to make the decision to change. Some vendors already sell hard drive based backup devices, but I find them to be costly and again dependent on a special 'drive' to pop a special carrier in and out of.
Encrypt the backups, handle the drives as carefully as tapes and I'd expect good results from the change. If you go with 3.5" drives, get all your planned number of drives/enclosures at the same time so the power adapters will match. For 2.5" drives you don't even have to worry about separate power.
