Do You Need More Space?
Do you ever get frustrated because you never seem to have enough space on your computer? My first laptop had barely 20 GB on the hard drive, and the operating system took about 3 GB itself.
That was a few years ago, now we can get a Terabyte on a laptop!
With all this disk space, why do we still need external drives? Well, have you tried to backup your computer lately? Some of the software that performs the backup actually needs 1.5 the amount of space (as it places some files in temporary memory – cache – during the backup procedure).
That means for a 4 MB backup, you would need a storage device with at least 6 MB available. For 10 MB, you would need at least 15 MB – got it?
The more downloaded music, eBooks, and videos – the more space you will need.
How Much Space Do We Need for a Backup?
So lets think about this for a minute. First, if I only need a total of 6 MB for a backup, why not just buy one of those little USB flash handheld drives? You can get one fairly cheap at any store.
I currently have a 2 GB, a 4 GB, and an 8 GB USB flash drive. I use these for different purposes. Since I am an author, I keep a backup of all of my book project files on the 4 GB device.
I use the 2 GB device for temporary storage and sharing of small amounts of pictures or files that I want to transfer to a family member’s computer when we go to visit.
The 8 GB was used for my laptop backup, until It became too small.
As I mentioned above, I am an author. I have several copies of my book files located on different storage devices. I am currently writing a second book, which will be larger.
The book files consist of several eBook formats and a print book file. Not to mention the cover files and all related notes. These all take SPACE.
Last year I ran out of space for my laptop backup. Let’s discuss backups for a second. We normally backup all of our document and desktop files ourselves. Normally the operating system backup function only backs up the operating system, and maybe the recent security patches that you have seen download and install on your PC.
Since many people are not aware that we are responsible for backing up our OWN files, it does not get done. This does not seem to be a big deal until something unexpected happens that destroys our files and PC hardware.
If you do not use surge protectors for your computer and entertainment hardware at your house, you are running a BIG risk. Please note that an extension cord is NOT a surge protector. When we suffer from either a power outage, or power surge (electric storms), our TVs, computers, cell phones and tablets – if charging, and all other electronic devices with a computer chip or board can be shorted out.
Imagine if you will, our normal household outlets are 110, with the dryer at 220 volts. When we have a power outage, total blackout or partial brownout, the electric company at some point turns the power back on. This causes power surges that could exceed the 110 /220 maximum threshold our electronics are built to withstand.
The same effect happens during electrical storms when lightning strikes your house, or near your house. Unexpected high voltage courses through your walls along the power lines until they reach an end. That end is normally your power outlet – and whatever is plugged into it.
You can buy electrical surge protectors in power strips, or for mounting on your wall sockets. They come with indicator lights so you know when they are working.
The better quality ones have a high joules rating – 1200 or more. This determines how much of a power surge they can protect your devices against.
