Troubleshoot file backup errors

After the backup is complete, the file errors are listed. When files of size greater than 4 GB are backed up, files are sent to a drive formatted in the FAT32 file system. Before you back up the files of size greater than 4 GB, format your backup drive using another computer to use exFAT or NTFS format. You can also use another drive that is formatted in either exFAT or NTFS format. Backup errors may also occur when sectors of the hard drive that is used for backup are corrupted.

1. Go to the SupportAssist OS Recovery home page, and then click START BACKUP on the BACK UP FILES tile.
2. Click START BACKUP.
3. Click the Advanced settings link, and then select the files that previously had errors.
4. Select the destination storage device to back up the selected files, and then click NEXT to begin the backup process.
5. If the error occurs again, run the diagnostics test.
