Any organization’s success is always linked to data and its privacy, key factor for success of an organization is to backing up mission critical data. Even in the current era so many companies prefer local backup instead of online backup just because to save money and to manager IT cost within budget limits. I don’t see anything wrong with this approach but real concern is the security and availability of the mission critical data. The main hurdle with local storage is the storage media such external hard disks, optical disks and DVDs which can easily get corrupted even though you store such devices in safe place. Even small accident or static electric discharge can make the data irreparable which would cost a lot to the company.
One of the best ways to avoid such failure is to go for online backup option. This can be done in 2 ways, one in which you can setup locally and another in which you can opt for service from external provide who can store your mission critical data on some secured hosted server which available 24×7. For local setup you need PCs with good physical memory and terabyte storage and make sure that all these PCs should not used for any other purpose than backup. This way you can make backup process transparent to end users and will be automatic task which runs behind the scene while normal work is going on. The real drawback is the expense related to hosting server and cost associated with resource management, in this case System Administrator.
Best way is to opt for backup service provider who has secured server and offers you monthly or annual plan. The thing about this option that you does not need to worry about anything as provider gives you complete package with reasonable rate and specialist to look at your backup task.
