With Nero BackItUp you can back up data. Click the Backup menu to start the desired backup task.
The following backup tasks are available:  
Autobackup
With Nero BackItUp, you can set up and configure Autobackup, the automatic backup feature. Once it has been set up, Autobackup is available on your computer’s system tray and backs up specified folders in the background.
Setting up Autobackup is particularly useful when you want to carry out regular backups for the same files. The advantages are, e.g. that all the settings for the backup have already been configured and that there is no risk of forgetting a backup date or of not carrying out a backup as scheduled (as long as the computer is on).
File backup
If you choose a file backup, the individual files and folders that you select are backed up. If you want to back up the same files again later, a backup update makes it easier and saves resources and other things.
A file backup is useful to protect against data loss that can occur due to hardware damage or force majeure (fire, etc.). As a result, we recommend frequent backups so that you can restore data that is as current as possible in case of loss.
Drive backup
If you choose drive backup, entire drives (hard drives and/or partitions) are backed up, including the programs and the operating system. You can select the drives to be backed up.
In contrast to file backups, drive backups restore programs and operating systems when restoring. So, a drive backup is useful to set up the whole operating system plus programs in case of hardware damage.
Verification
Nero BackItUp can be used to verify an existing backup. Nero BackItUp verifies whether or not the backup can be used for a successful restore process. During this process, data integrity is checked, and the backed up data is compared to the source data. If you carry out the verification right after the backup and have not modified any data in the meantime, you can use the feature to verify whether or not all data was backed up successfully (data verification).
