I am using Mozy Home. You get unlimited data backup from your pc's internal hard drives for just a few quid a month. The peace of mind is brilliant. The first backup takes AGES! I think mine took two or three weeks. However, after that it just backs up files you have added or changed on a regular basis in the background. I have never had to get my data back so I can not tell you how that experience is. I can only hope it is good. As well as downloading data i think you can pay to have it sent back to you on a dvd. Read up on their web site and make your own mind up.
My backup plans are as follows:
Data stored on internal hard drive.
Offsite backup via Mozy Home
Onsite backup via a USB hard drive synched up with my internal hard drive via free software called synctoy (i have not done this bit yet)
Originally I bought a NAS device with two hard drives mirrored to store all my data on. However, I realised that if my house was burgled or burnt down etc my data would be lost. That is why i got mozy home. In an ideal world I would not bother with the internal hard drive for data and the usb hard drive. I would simply use my NAS device with it's mirrored disk as onsite backup and then offsite backup using Mozy or whatever. However the problem is that Mozy Home does not backup NAS drives. It only backs up internal drives. If you want to backup NAS drives with Mozy you have to buy the Mozy Pro service and then you have to pay per GB of data and it becomes expensive.
I have not yet worked out what the best way to ARCHIVE data is
I thought about storing all my pics on hard drives and when they fill up just stick them in a cupboard. However, I have read that this is a bad idea as the lubricants in the hard drive dry up and it will stop working. I am wondering if blu-ray is the way forward. Problem is my hi-def video camera produces large files so it will still be a lot of disks.
Hope that helps a little,
