There are not many people remember when 9600bps was a fast communication. Now days, you are looking at several mega bits for internet download accesses.
So, how fast is the 1 mbps. 1 mbps means 1 mega bit (not byte) per second. 1,000,000 bits per second. That is 125,000 Bps or 125,000 character per second. At this rate you can receive 1 floppy disk full of data (1.44MB) every 11.52 seconds. ! Giga Byte is 1,000 times the Mega Byte. So in order to receive Giga Byte of Data, you must spend 11,520 seconds or 3 hours and 12 minuets.
Now lets look at reality. When the Internet Access Company promise you up to XXmbps, they are promising UP TO that amount. You rarely get that full burst of speed. Besides, when they say XXmbps, that is for download only. So, when you want to send large file,you will need much more time.
Does Online Backup Work?
The answer is Yes, but if you are only backing up data or a system or application. What is that mean? If you are using Microsoft Windows and Microsoft Office, you will have no problem backing up all your Excel, WORD and PowerPoint documents online. But you will need a lot of time to backup entire Windows OS and Office Application Programs.
That does not mean you should not back up your OS and application. You hould do so using local disk or Network Storage (on-site). Remember, your LAN (Local Area Network) can be as fast as 1gbps. That is 1,000 times faster than your 1mbps Internet access.
What is the Best Backup Solution?
One of the best setup for small to medium size businesses are:
(1) Setup local storage server to backup entire computer on the LAN.
(2) Use the Off Site Storage for Documents and Data.
This way, if anything were to happen, you have full back up on the premise and in case of total loss at your location, you will have data at off site.
