I have been using computers for at least 10 years now. The one thing i've found is to backup, buackup and backup again files you do not want to lose. I started with floppys and had 800 of them with backups. Only problem is that sometimes they get corrupted. So i tried a Imation 120 MB floppy style external drive. Worked great and i loved the extra space. But the price of the floppys and that they also can become corrupted killed that idea. Finally there were cd burners. OH Joy, that i could save 650 MB of datain one place. The only problem that cropped up was cheap disks that peeled the metal backing layer off rendering them useless. But even today i like backing up weekly data if its not enough for a dvd. And finally there are DVD's that let you backup 4.3 gigs per disk. I use these for my main backups at 20¢ for each disk. The good part about saving to disks is that they can be transfered to any computer that can read the disks. Nec dvd-rw burners are only $35 at newegg. Why worry about dual layer. It takes what 8 minutes to burn 4.3 gigs to a dvd? 20 dvd's is 86 gigs and it takes less than a half day to burn them. I use the ridata disks that cost me $19.60 for a 100 disk set.
About using hard drives for backup.
I was talking with my doctor one day when his secretary informed him that the computer he was using for backups would not start. At that time i mentioned that i did not trust hard drives for backup purposes unless it was for short time only. He asked me why so i told him that any machine with moving parts is bound to wear out someday and computers are prone to do this quickly. I then told him about my methods to backup.
This doctor, a few weeks later, remembered what i said and asked me how he could do this. So i set him up with a cdburner and showed him how to do weekly backups. The hard drive that was in the computer that would not boot had died and although he did not lose his data it took his secretary a week to recopy all the paper work to another computer. He is now delighted with the system and likes the idea that he can replace all data and even install new computer without losing any time over installing the data. It also seems i have 6 other doctors i am under contract for to do backups on their systems. Word gets around i guess.
The moral? I would not trust backing up any data you cannot afford to lose to a hard drive. It could die at any given moment. Maybe for short periods of time (30 days or less), but for true backups use dvd's or CD's. I still have software i bought years ago that i still use on my newest computers. My Syntrillium Cool Edit 2000 was bought out by Adobe and now costs $250. It's still the best sound editor anywhere.
