The purpose of an online backup is, of course, to improve data security. The idea is to safeguard data from loss or corruption and – for this to be effective – there are a few things to consider.
Perhaps the most obvious – and most important – is what exactly you want to backup. Some people just backup their entire hard drive to make sure they don’t lose anything but what if doing that is prohibitively expensive? You might not be able to afford backing up all the data you have and need to prioritize instead. Needless to say, priorities differ widely between individuals. The most important data to a photographer would probably be his media files while a businessman would put a far greater value on his documents containing financial and client contact information. For this reason, it’s a good idea to figure out which files you need the most if backing everything up isn’t an option.
Tying into the last point somewhat is the selecting the type of online backup you need. Many providers supply software that handles the back-up process automatically but you might prefer to manually select what you want to save and do it on your own time – especially since cloud backup software running in the background can be a drag on computer resources.
