I thought I did not really need a system for this but I am wrong. Files are easily deleted by accident, viruses can ruin your computer and any other number of things can occur that will loose or save over your previous work. If the error lies in the new work that was saved over the older work then you are screwed.
Here’s the system I recommend
Have an external hard drive from day one of your new venture. That includes the research. I mean as soon as you’ve made the decision to start your own company.
On you hard drive create a back up folder. From which one folder from your laptop will be transferred to every two days.
Within the backup folder create two additional folders.
One folder will be labeled “old” and save your data there. The other folder should be labeled “recent.”
I suggest you rename “recent” to “oldV2″ before backing up your work. Then back up to a new folder and name it “recent”
I you do this you will always have two copies of your data. One version two days old and another one day old. This way, if you have saved a error over your most recent backup you won’t be stuck. You’ll have an older version available without the error.
The “old V” can be iterative by just changing the number to 3, 4, 5 and so on.
I recommend you back up your work every day. It seems like a pain but believe me I’ve just lost 2 weeks worth of work by saving an error over my older work and now I’m stuck with the error.
So above is the system I’ve developed to ensure this doesn’t happen to me again. If my business was up and running I would have lost two weeks worth of revenue from a downed website and had the costs of labour of reworking the site.
Understand that this applies to more than a website, a sales presentation, a business plan and so forth..
Best of luck!
I actually had the misfortune of having been too lazy to make a back up copy of the files i was working at… then the computer’s hard drive got fried—- and all my work gone… i had so much trouble re doing everything from scratch. Yes. so I totally agree on making a back up.
You poor thing! It can be devastating considering we just about hold our entire lives on our hard drive! Somehow we have to find the bright side in all of it. =)
