I read something recently that stated DVD's like you buy in the store can lose their ability to read after something like 5 or so years. I have been putting personal data on DVD's but every time I want to back everything up it takes about 3 DVD's which isn't too bad but I would like it if I could feel confident they will last many years down the road if I ever need to restore data from them.
One idea I had is to buy a good size flash drive and then use a robo copy script once a week or once a month to copy everything to the flash drive, maybe alternate through two or three flash drives, and when not bakcing data up they would be kept in a fireproof safe and probably one drive at my parents house or possibly a safe deposit box at a bank. Depending on how much data I back up and the size of the drives I with three flash drives I could possibly keep about 6 full backups available between the three drives.
Another option is a solid state drive since I think they are more stable than a hard drive with plates but for the cost, unless you need the amount of space I don't know if it offers anyhting more than a flash drive considering what I am thinking about using it for.
So a few things I would like to ask are....
1. Is that true about DVD's or are there certain brands or types that will last indefinitely for data backups?
2. Are there any other options that a re good for home backups? I don't like the idea of using a normal hard drive since it can be damaged easier by impact. Network storage is good too but again one bad zap and you could lose it all.
3. Would a flash drive work Ok like I mentioned above, would it be more stable over the years than a DVD? As far as I know flash drives will not damage or lose data unless you unplug them incorrectly, assuming it is a good quality drive and not a knock off.
4. Would a solid state drive be better/worse/same, they cost a lot more that a flash drive though.
