Power outages and documentation

As a rider to my use of coffee to prove a documentation methodolgy, we had another proof of the scheme's robustness a couple of days ago.

Under the scheme, data is saved twice, once to the computer's local drive and secondly to a USB stick. The data on the computer's local drive is also backed up to OneDrive, and entrusted to Microsoft to look after.

The crucial point is that you don't need a functioning internet connection to carry out documentation - as long as you have access to one somewhere in the piece to back the data up everything is fine as you always have at least two copies of the data - very useful as I found in the coffee pouring incident as I was able to check and confirm that all the data had been backed up.

This time it was the power company. The power went off with an unscheduled outage, and more importantly stayed off. However as I had (conservatively) about three and a half hours of battery life left on my computer and the same on my phone - I use my phone to take pictures of the artefacts and transfer the data to my computer. Normally I recharge my phone as I go from my laptop, but obviously I didn't do that once the power went off - a severe case of robbing Peter to pay Paul.

So, with three and a half hours worth of power I could stay working.

Which I did - the only limiting factor was that it began to cloud over in the early afternoon, and the light began to go, making it difficult to work.

Once home, I powered up my laptop, let it sync to OneDrive, and hey presto, we were done and backed up...
