I was working from home one day, it was pretty busy morning. After I wrapped up all my meetings, I thought I would take a break stepped out of my home office. At that time my son who was 16 months old and ran in to my office and gave me a hug. I lifted him next to my desk where all my cables were running up and down to connect all my devices to my PC. I had Printer, External Harddisk, Speakers, etc. Accidently my son pulled the cable which was attached to my external harddisk. I was somewhat concerned because all my PC data was being backed up to my external HD. So I asked my wife to take care of my son and checked the disk after reconnecting it to my pc. The disk would not power on. I researched online bought few cables to directly connect to the HD. All my effort to restore the data failed and I permanently lost the data in the disk. Although I lost the data in the disk, it was a copy of the data that I already had in my PC and other storage devices so it was not that critical.
This may not be the case for everyone. You may loose all the data in your pc, laptop or tablet if the data is not backed up. It is critical that you back up your data as all forms of documents are created and shared electronically. There are many vendors who provide these services through online. You can also buy an external harddisk to back up your files at your home. I strongly recommend that you do one or the other. You must avoid a single point of failure and enable redundancy where you keep a copy of your data in another location/device etc.
We store pictures, videos, purchased movies, electronic documents etc in our PC and we rely heavily on it to produce those document when it is necessary. I would strongly recommend for any one who is reading this to do some research and start backing up your data to another storage device. You may back up to a device locally at your home or back up your data over the internet to a cloud system.
I have several vendors listed here for you to choose from. I personally do not endorse one over the other, I leave it up to you to do the research and pick one that works for you.
There are also many devices sold in the market that would same job. You can go to a Walmart or Bestbuy and buy WD, Seagate, Samsung External Harddisk and install it at your home.
