Typically, data storage falls into one of two overarching areas ?? onsite backup, which is when data is backed up at a business' location, often on a common server; and offsite backup, which means that data is copied and stored apart from the main network. According to WiseGeek.com, Offsite backup is beneficial for users who "often rely on telecommuting with portable computers or mobile devices and who therefore are not always in direct contact with the network they typically access files from."
Within these two overarching methods is a world of available options. And questions: Where do you want to keep your backups? How many copies of it are sufficient? Who has access to what? How much space and money can you allot to data backup? How do you manage backup for your employees who travel and need to tap into a central system?
There are a few methods on which these back-ups can be generated. No one method is a perfect fit but knowing them all can definitely help in taking a good control on disaster planning.
Cold backup is an automated process that makes an image copy of your system data, usually at a set time, and usually late at night when no one is around. Cold backup acts as a sort of "time machine" for your data when disaster strikes ?? you are able to go back to a specific date and retrieve the data for your entire system. The image copy cannot be updated, and data cannot be accessed while the backup is in progress.
Hot backup, a.k.a. dynamic backup, can be done even when data sources are being updated. It is a file-by-file process that can be done automatically, but usually is done by users. This is an advantage in multi-user systems because hot backups do not require downtime, like cold backup does. The downside, however, is that data created before the next backup will not be saved, so if disaster strikes between the time you create a file and the time it is saved, you will lose all your new work.
Cloud storage a.k.a. offsite backup that offers the advantage of having no physical space requirements and is the ultimate form of remote, offsite storage. And, unlike older methods of hardware-based backup, cloud storage offers the advantage of being automated ?? the data can actually backup itself, into a safe, encrypted network.
But cloud storage is but one component in the data storage and security picture. Whenever data is retrieved or accessed from an online system it is exposed. Also, you have to be able to get online to get to it. What happens, for example, when your traveling sales team needs to access records but cannot get onto the network?
The safest place…Continuous backup, a.k.a. continuous data protection and real-time backup, is when data is automatically backed up in a secondary location whenever a file is changed or updated. When a computer crash hits, you will always have the latest versions of all files.
At easySERVICE™, we want to improve your backup strategy, not fix it. And we believe that the safest way to store your data is through a multi-layered strategy involving multiple storage locations and real-time backups. But should disaster strike anyway, you can trust easySERVICE™ to recover your data and help you get back to business.
