I used to treat my PC the same way as I treated my mainframe, with tape backups which I stored off-site. Nowadays, my PC (it's now an Apple) has a local hard drive back-up, and an off-site backup that I back up on-line. I really should get another local drive that is ready to boot with last Sunday's backup, as my local hard drive has Time Machine on it, which has a different function. So what's so different about my PC needs and my mainframe needs? The only real difference is when it is cost effective to have a remote computer room ready to run when my computer room gets hit by a meteorite. Disks are cheap. We've been throwing disks at our databases instead of doing the old analyses of the past, and it is cost effective. Bandwidth is cheap - why ship tapes out when we can get the backups off site virtually instantly? Our tapes will all be gone within 2 years. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
