Backup weapon, the ultimate anti-data-loss weapon
Simply put, backup means keeping a second copy of all your important files and storing them at a location which is relatively safe from perils like, unexpected power failure, hard disk failure, virus attack and the like. What every one needs to understand is the fact that backup is the only definite way of safeguarding against the reality of data being a very vulnerable entity, prone to different kinds of threats. Depending upon the relative importance of the data, it is imperative that users take adequate measures to backup data in order to avoid data loss.
Not just backup but frequent backup!
The best prescription for avoiding data loss headaches is to backup your important data, not just when you feel like it but on a regular basis. If you use one of those reminder services on your desktop, make sure that you schedule a backup reminder first thing every time you start the computer. The essence of backup is to have all your important data safe in the event of an unexpected virus attack or a hard disk crash. For the backup files to be relevant and useful, it is important to ensure that backup files are up to date.
This is especially important as time factor plays a significant role relevance of data. In the case of a banking sector company, what is the use if the system administrator forgets to back up the current year's retail banking data but has systematically done a backup of all the previous years files. In case there is a system crash at the bank, most recent data would be lost without a trace.
Backup makes sense, always, even money-wise!
Even though data recovery technology has improved vastly and is undergoing sweeping changes with each passing day, the cost factor may not always be encouraging, especially from an economic point of view. If you end up with signing up for the services of a data recovery company, then rest assured that you would be poorer by several hundreds of dollars. Hence, it is always a wise decision to protect yourself against data loss.
There might bankers or insurance companies out there who would be willing to insure your data for a humongous amount of money, but they can not insure you against the possibility of a potentially devastating data loss.
Only regular backup can do that magic! Experienced system administrators and home users swear by the simple fact that the best way to insure your important data against all kids of threats is to make regular backup of the files. More importantly, keep updating the backup files on a daily basis. In case of companies or firms, it would be a wise system administration policy to have a daily checklist of things to be done, with backup being listed up among the first things to be done.
Same backup rules applies for individuals handling important data and working on systems or networks, which are potentially vulnerable to data loss.
