When creating a system image backup or file backup using Windows backup tool, you may get the message “Windows backup failed: the system cannot find the file specified; 0x80070002". It may also tell you which specific file that cause this error.
1. If you are given the location path of the files specified, which is possibly because the folder is not present on your computer any more. Some files are generated only when a certain program is installed. Once, you remove it, the files go with it.
2. The source volume included in the backup has some disk errors.
3. Connection problems may also cause backup error 0x80070002 when you backup to USB external hard drive or NAS network location.
4. It will also cause backup cannot find the file specified if the snapshot on the source partition has been deleted while backing up.
5. On MBR disk, there is a hidden system reserved partition containing boot configuration data (BCD). If this partition goes offline and then Windows Backup cannot access it, resulting in the error Windows backup cannot find the file specified.
1. Skip the file, if the file that cannot be specified is not important. Then the backup will probably goes on. If it does not work, move the folder that contains the file which cannot be specified to another location on your computer and then try the backup again.
2. Press Win key + R key, type “CMD”, and press Enter to open an elevated command prompt. Use command “chkdsk [drive letter]: /f” in a command prompt to check and fix disk errors. For example, if you get the error when trying to backup C: drive, then you should type the command : chkdsk C: /f
3. If you are backing up to external USB drive, make sure it is well connected and is formatted with NTFS. If you are trying to backup to NAS location when you receive this error, try to map the NAS location as a network drive and start the backup again.
4. In an elevated command prompt, type “vssadmin list shadowstorage” where you can see the shadow copy storage space that are currently in use. Then use “vssadmin resize shadowStorage” to increase the maximum shadow copy storage.
5. Assign a drive letter to the hidden system reserved partition and set it as active using Disk Management or third party partition software.
If the backup still fails after trying these steps, you may consider use another backup program.
Windows Backup alternative
Third party backup and restore software, AOMEI Backupper Standard allows you to perform backup and restore with a smother way. It can include every file, folder, system, partition, or even the entire hard drive in a backup. You can use it to backup to external hard drive, local disk, NAS network shared folder, or other locations. For auto backup, you can use full backup, incremental backup or differential backup. For example, to create a system image backup with AOMEI Backupper, you can follow the steps below
1. Download and run this backup software.
2. Click “New Backup” or “Backup” tab, and then select “System Backup”.
3. The necessary partitions for a full system restore will automatically be included in the backup source, so you just need to click “Step 2” to specify the backup target location.
4. Confirm the information and then click “Start Backup” to start the backup process.
AOMEI Backupper uses block level backup, so you would never have such error like the system cannot find the file specified. What’s more, the backup process is much easier and quicker. After the backup is done, you can also create a bootable media so that you can restore system when it is not working.
