What is NBService.exe?

The genuine NBService.exe file is a software component of Nero BackItUp by Nero.
NBService.exe is an executable file that runs the Nero BackItUp program, an application designed to backup up important data to Nero's cloud storage network. This is a critical component for Nero BackItUp and should not be directly removed. Nero BackItUp was originally a part of the Nero Burning ROM Suite, but later was sold as a standalone product. The product offers the backup utility for up to five computers and unlimited mobile devices including iOS, Android and Windows. The program can be assigned to automatically backup data from hard disks (USB & Internal HDD drives), CD/DVD/Blu-ray discs, network storage space and the cloud. Nero is a German software developer best known for their flagship disc burning software program, the Nero Suite. Richard Lesser founded the company in 1995 as Ahead Software GmbH but the company changed their name to Nero in 2005. Nero became quite popular after many OEMs (original equipment manufacturers) decided to bundle the suite with their hardware products. Nero is headquartered in Karlsruhe, Germany.

User Comments

Hard to get rid of whitout uninstalling all of Nero. Takes some memory for doing nothing...
Nbservice.exe is a process that belongs to Nero AG’s Nero BackItUp utility. This application creates backups of selected files, folders, partitions, and hard disks to other hard disks, network drives, CDs, DVDs or FTP.
Installed with Nero Suite 9 (possibly others) even when Nero BackItUp is NOT installed. Unsure whether it's actually used by Nero when BackItUp is not installed.

Best practices for resolving NBService issues

A clean and tidy computer is the key requirement for avoiding problems with NBService. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
