March 31 is dedicated to the visibility of the transsexual community, but also to the storage of data.
World Records Day
In the last week of March 2010 some users of the social networking site reddit had the idea to dedicate a day to archiving computer data (backup).
Their purpose is to remind users of computers and "smart" mobile phones of the importance of storing data that their eventual loss due to non-archiving, in addition to the emotional value for the simple user, can also have a financial impact for the professional and the businesses.
The idea resonated, the external hard drive companies embraced it and thus was born the World Backup Day, which is celebrated every year since 2011, on March 31.
