Computer backup systems save important data to additional storage devices, such as floppy disks, CDs, USB drives, or hard drives. Operating systems and programs offer backup options, and scheduling regular backups is recommended. Business-grade systems are more secure and use redundant local storage devices combined with offsite data centers.
Computer backup systems are a method used to save important information to one or more additional storage devices. Important data can be copied to various types of storage media, including floppy disks, compact disks, and universal serial bus (USB) thumb drives. For more storage space, some users purchase additional internal or external hard drives. The most reliable computer backup systems use one of these local storage devices in conjunction with an offsite backup server. This system allows for data recovery even if the physical location of the computer is completely destroyed.
Many computer operating systems (OSs) and programs offer ways to back up important data. Most operating systems have systems for creating backup discs, taking a snapshot of the hard drive, and establishing a system restore point. Using these features can help a user recover data, or even the entire system, from a software or hardware failure. Some users choose to schedule a daily, weekly, or monthly backup so they don’t have to remember to do it every time. Some types of software, such as music management services, will often remind users to back up their purchased music and other file types.
The means used to back up computers vary based on the amount of data to be archived, the level of security required and the importance of the information being backed up. For many home users, copying their financial documents, family photos and videos to an external hard drive or compact disc will be enough to protect important files from a computer failure. Keeping an extra backup copy in a safety deposit box or at a friend or family member’s home will ensure that your data survives hazards like fire and flood. Students may want to back up their homework as they go along to avoid missing important projects. Remembering to back up your data is the first and most important step in any computer backup system.
Business-grade computer backup systems are generally more secure and reliable than those found in most home systems. Businesses need their computer systems to function effectively despite hardware or software failures, and they also need to prevent competitors or cybercriminals from compromising sensitive data. Many businesses use redundant local storage devices that can store large amounts of encrypted data. These devices are combined with offsite data centers that ensure that important information will be safe in the event of a widespread disaster such as an earthquake or hurricane. These systems often require high-speed bandwidth to transfer large volumes of files in a reasonable amount of time.
