In information technology, backup refers to making copies of data so that these additional copies may be used to restore the original after a data loss event. These additional copies are typically called "backups." Backups are useful primarily for two purposes. The first is to restore a state following a disaster (called disaster recovery). The second is to restore small numbers of files after they have been accidentally deleted or corrupted. Data loss is also very common. 66% of internet users have suffered from serious data loss. Since a backup system contains at least one copy of all data worth saving, the data storage requirements are considerable. Organizing this storage space and managing the backup process is a complicated undertaking. A data repository model can be used to provide structure to the storage. In the modern era of computing there are many different types of data storage devices that are useful for making backups. There are also many different ways in which these devices can be arranged to provide geographic redundancy, data security, and portability. Before data is sent to its storage location, it is selected, extracted, and manipulated. Many different techniques have been developed to optimize the backup procedure. These include optimizations for dealing with open files and live data sources as well as compression, encryption, and de-duplication, among others. Many organizations and individuals try to have confidence that the process is working as expected and work to define measurements and validation techniques. It is also important to recognize the limitations and human factors involved in any backup scheme. Storage, the base of a backup systemFrom Wikipedia under the
GNU Free Documentation License How can I backup a computer that is starting to crash and has limited services? Q. I'm trying to back up a Vista computer. However, it's starting to crash and numerous services cannot be accessed. Because Task Scheduler can't start, the backup and restore program won't let me backup. Is there another program (not downloaded from internet) that can do the same or is there a way I can manually back it up? And is there anything I can avoid backing up to prevent the crashing again?

If your computer is a desktop pc then you can try putting another harddrive with vista installed on it into your computer and booting from that partition. If you can do that and vista recognizes the breaking Harddrive, copy everything off that harddrive onto the new one. Otherwise you just need to buy an external, plug it in and copy all of the files you want to keep off. If you have a spare internal HDD that you can use that would work as well. If windows doesn't let you use usb devices, won't recognize the new harddrive you put in (or you don't have one) then you could try networking your pc to someone else's and then transferring files over… [cont.] Answered by unknown - Fri May 29 06:32:16 2009 What is the safest way to backup my computer?

Q. I am running Windows XP. I have a 40gb on my laptop, with 4.28 gb of free space. I have a ton of files and no centralized backup. What is the most efficent, space and cost wise, way to backup my hard drive? Asked by mbtafan - Fri Sep 1 17:14:22 2006 - - 8 Answers - 0 Comments A. With 36GB of data, you have too much to consider using CDs. I'd say get an external hard drive which connects via USB 2.0 to your laptop. (If you only have USB 1.0, it'll take a lot longer, but it's still the only reasonable way.) These things aren't very expensive, only a little more than an external dvd drive. Last weekend I saw several of them on sale at office supply places like Staples, OfficeMax, and Office Depot. After the backup is done, be sure you disconnect the external drive and store it some place away from the laptop. Makes sure that some catastrophe, like fire, won't destroy both laptop and backup. You probably need to move some of that stuff off your hard drive anyway. With just 10% free space, your laptop must be… [cont.] Answered by OR1234 - Fri Sep 1 17:30:57 2006 From Yahoo Answer Search: "Backup" Quotes regarding Backup This theme article is a stub.
