Since I worked in tech for 27 years, backups have always been a issue. In the company we use to spend a great deal of time discussing how to properly back stuff up. Yet most of our backups didn't really do what they were suppose to do...so we were still left scrambling when we had a major failure. So I've learned to appreciate them the hard way.
Now that I have my own business (accounting,
credit card system backups, CAD drawings, etc, etc) and the amount of digital info at home (pictures, kids school assignments), I needed to take the same approach...especially when a virus almost took all my data (and backup) a few months ago. That would have been catastrophic for us!
Once set up, its all automatic (except for the hard drive switch once a week). Even the posting to secure directory on my domains is done after hours with a macro program (workspace macro).
Not doing this IMHO is irresponsible. Let me ask you guys...how many of you do regular backups on your
credit card servers, WSII or other entry systems for your automatics, etc? What would happen if you lost that info in a power surge or the like?
I've taken other measures to deal with stuff...like I use GMAIL for all our mail, calendars, etc. Put my pictures and video on Picasa, youtube, facebook. Voicemail, faxes reside on my toll free service. That way its on the web and not on my machines. I use online billing instead of paper so they keep my records. I'd like to get to a point where all this resides on the ether and I don't have anything at home or the wash.
I guess this comes from my "what if" scenarios I always had to deal with when I worked for wireless phone companies as they are considered 'lifelines' to emergency services. All these concepts are what they think abut in network ops and engineering on a daily basis.
