For the past two decades, electronic files have been replacing hard copies. Thick boxes of files have transformed into thin think pads. When rodents, fire or calamities destroyed the data files, there was no way it could be recovered. No kind of back-up helped to recover the important files. But this is not the case today. However, technology has made it possible to always keep a backup. There are few reasons to keep backup of your work and one of them is to avoid repeating the work. We put hours of effort and tons of creativity in creating presentations, documents, reports, charts, sheets, etc. Of course, entire work can’t always be repeated to recover the lost data.
Next reason is to save time; recovery or recreation will both require significant amount of time. Time might not be available at leisure at every occasion to get the work done. Another reason for having backups is availability of raw data. A huge amount of data is collected and piled up to create a report. Say, due to some reason, the final report is lost and there is no backup file available. Even if there is time and efforts can be made, it is very less likely that all the collected data will still be available around for the work to be redone.
The most important reason is money. Any work done in this world requires money. Redoing work for lost data will require lots of money. Organizations might not be willing to afford to pay double amount of money for the same work to be redone.
