What is a .NBU file?

Backup file created by Nokia Suite (formerly Nokia Ovi Suite) or Nokia PC Suite; contains a backup of cell phone data and may include contacts, calendars, text messages, and other user data; used for restoring data to the same phone or transferring data to another phone.

What Are Common Causes of ".NBU" Files Lost or Failure?

There can be several common causes of ".NBU" (Nokia Backup) files lost or failure:

  1. Accidental deletion: Users may accidentally delete the ".NBU" files while managing their data on their device or computer.
  2. Device malfunction: If the device experiences a hardware or software malfunction, it may lead to the loss or corruption of ".NBU" files.
  3. System or software crash: If the operating system or backup software crashes during the backup process, it can result in incomplete or corrupted ".NBU" files.
  4. Virus or malware attack: A virus or malware infection can corrupt or delete ".NBU" files, making them inaccessible.
  5. File system errors: Errors in the file system, such as disk errors or file corruption, can lead to the loss or failure of ".NBU" files.
  6. Improper file transfer: If the ".NBU" files are not properly transferred from the device to the computer or vice versa, they may get lost or become unreadable.
  7. Formatting or factory reset: Formatting the device or performing a factory reset without proper backup can erase all data, including ".NBU" files.
  8. Storage media failure: If the storage media where the ".NBU" files are stored (such as SD card or computer hard drive) fails or gets damaged, it can result in the loss of ".NBU" files.

It is important to regularly back up ".NBU" files to avoid data loss and utilize data recovery methods if necessary.
