![]() In addition to a local backup, maintaining an offsite cloud backup is an important part of a backup strategy. Many backup utilities, like macOS's Time Machine, allow you to restore a backup from a specific date, rolling back to a version of a file before any unwanted changes. Make sure that the backup includes the folders you're regularly saving files to, and that any external disk you're backing up to remains connected. Most operating systems now include built-in backup utilities that automate the process, making frequent backups without any effort on your part. However, that method relies on you making frequent backups whenever data changes - if you lose a file and the most recent backup is two months old, you've lost all of that progress. The simplest backup method is to manually copy files from the primary location to a backup location. Finally, keep one of those backups at a different location in case of theft, fire, flood, or other disasters. Keep those backups on two different types of media - for example, one on an external hard drive and another on a flash drive. First, keep three copies of your data - one primary copy and two backup copies. Many experts recommend a backup strategy known as the 3-2-1 rule. So how do you back up your data? Most operating systems include built-in backup features that help you get started, but there are some best practices to follow that can keep your data safe in case of disaster or emergency. If you don't have backups of your important files, an unexpected event could erase them for good. Program installation conflicts can make applications or files unusable, and software bugs can accidentally delete files and folders. You may mistakenly delete files, or a virus may corrupt or encrypt them. File system corruption can damage directory structures and cause entire folders to disappear. Software problems can also damage your files. Hardware malfunctions are not the only reason to maintain backups. An electrical short or physical damage (especially when it comes to laptops and mobile devices) can cause data to become unrecoverable, so it's wise to maintain backups of important files on multiple devices. However, like all electronic devices, they are not immune to problems. Most computer components, like hard drives and solid-state drives, can run for years without crashing. Better yet, you could save the backups to a USB flash drive, which would also protect the files if the hard drive failed, or even save a copy to a cloud storage site in case an accident causes damage to both the computer and flash drive. ![]() For example, you may save several copies of a research paper on your computer as backup files in case you decide to use a previous revision. Backup is the most important computer term you should know.Ī backup is a copy of one or more files created as an alternate in case the original data is lost or becomes unusable.
