What do you call an extra laptop battery, having two internet connections, you call it a got to stay in business system for a mobile office.
I asked Mike in Mumbai, India what he called backup systems, he said, "I have Vonage because Skype.com went down for seven days a couple of years ago, and last year for two days." "I call these got to stay in business systems."
Backup or Redundant Systems for Mobile Office:
When the laptop breaks, maybe I can use HT Touch pad, when that breaks maybe I use a Smart phone.
One battery goes bad, I have 2-3 extra Laptop Batteries.
2-3 Cell phone Batteries
Cell Phone camera to backup my Canon Camera.
I have an extra headset for Skype.com, it is not always possible to buy a small headset in all countries.
I publish all my photos to server, and backup on my computer hard drive.
I have a external hard drive that backs up my computer hard drive.
I backup my thumb drive memory onto my computer.
I have a copper wire that I use for a universal electrical plug converter. If I change countries, and I have not yet purchased a converter, I use it.
USB Wireless Modem for Internet recharge or you prepaid cell phone,
By keeping an unused load for credit in my pocket, I am always insured I have credit to load onto my USB Wireless Modem or my Cell Phone. I then can buy my backup card when I go out again. You could be making a phone call at midnight in Thailand, that is noon in New York, the time runs out and you cannot not call the important business person back.
