External hard drive – External hard drives are more expensive than internal hard drives, but they are easier to use and relocate.If that hard drive fails, we will lose our original data and our backups. We should try to stay away from storing our backups on a different partition that exist on the same physical hard disk as our system partition. After the backup is complete, we can even install the drive in another computer and perform a restoration data to that computer. Second internal hard disk – Hard drives are relatively inexpensive these days and always available unless of a major malfunction.The available destinations for our backups are: We can’t allow ourselves to take a backup only to find that we can’t restore from it, or that we can’t find the backup media. Backup media should be stored offsite to prevent the same disaster from affecting the network and the backup media. In general, we should back up user data more often than system state data, since user data changes more frequently. In other words, we have to protect our system before there is a problem. Also, we have to test our backups and store the backup media in a safe place. Backups must be performed while the system is in working order. Backups are also useful in restoring deleted or changed files. We should backup anything that we don’t want to lose or that we don’t mind redoing. Backups are used for recovering our system state or user data in the event of a hardware or system failure. Key terms: backup, system, data, files, restore, user, disk, state, previous, media, version, automaticĪ backup is a copy of files and data on our system.
