backup schedule

[has55]

ok, I think I got some of it. You are saying the cheapest way for a backup, if money is a factor, is to partition the External HD into 4 parts. Take a snapshot of the drive weekly and store on one of the partition, such as wk1,wk2,wk3. But on week 4, 30 days later, how do you get a backup that shows the last 30 days. I know this is simple, but I a little lost at this point. ? And if you can afford it, use separate drives for each week.

Would you or anyone else that has this down explained how they have their ext HD backup setup for the best protection of their data, since ext HD are at a much lower price at this time.
Does anyone do daily or is that a waste of time or to redundant?

I know dave, you probably have a big system, but a simple format would be helpful. The guide has been extremely helpful, I just need to tweek out the last details in my mind.

Thank you.
