Iam looking for advice on making a long term storage solution for my home storage system. Presently I use RAID (2*75GB) and sometimes I burn important files on CD-R, but I don’t have a “complete solution” as of now. Ive decided that what I need is to keep every version of every file “forever”, so I’m really looking for some kind of archival utility. Long term comparability is key, so currently I’m fixed on using CD-R or DVD-R, since these media will probably be in common use for the next couple of decades. The problem is documenting where files are placed. Most backup software isn’t usable since it has another focus and primarily concerns itself about restoration of entire drives, not keeping track of different versions of files.
Right…music and movies are not going to stick on these media for centuries too! With the DVD debate still ongoing you’re half right…it can take some times. But other data type can be moved to other medium (tape). IBM and Storage achieved 1 TB on tape. It will still takes few years before going full production. They must act very fast because disk are getting cheaper. In the mean time you are going to see 200 GB native or above before end of this summer from various vendors. Depending what you are considering long term it could mean different thing. For me long term is anything above 7 years. In storage industry today the capacity increase very fast and become cheaper.
That been said you have to look at the OS and application who support these devices too. How long it takes to get obsolete in this area…3 years or so. That mean your applications need to follow. Who’s going to support Oracle 7.x today when they say it’s End Of Life and they are forcing you to migrate. What happened if your applications used some dirty trick to get faster under DOS and cannot be ported to Win2000 (games for example). What OS was popular 18 years ago…Windows or DOS.
