It's one thing to loose data and money because of hackers and thieves of various kinds; it's a different thing again when it's because you didn't back up your data properly or not at all. Value you data! Whether it's that critical business document, your thesis, your website or your home accounts and precious photo's.
Data can be lost through power surges, computer crashes, fires and theft to name a few. You wouldn't leave your home unlocked and doors wide open without any occupants, so be sure to close door to possible losses and theft of data.
The most important aspect of this issue, is to properly back up. So here are a few things to look for when considering a data back up solution.
1. Is it automatic?
You don't want to be using a system that is dependent on human action and consequently vulnerable to being forgotten or misused.
2. Is it simple to use?
You don't want something that's complicated and time consuming to understand. You need a set and forget system; at least until it's needed!
3. Is it secure?
Your data must be off-site. It is no good having a back up file on your PC. It must be remotely stored on at least one other PC. If your PC has a major fire etc hardware maybe lost but data and profit is safe.
4. Is it confidential?
A sad fact of life is that there are those around that get their kicks from destroying or stealing your data. Make sure system you use is encrypted to at least 448 bit and password protected. That way total privacy gives peace of mind.
