A letter or symbol error can cause command-line error, so you should make sure your command-line is correct at first. See here for the full use of the command:

xcopy "[source]" "[destination]" [options]

Make sure to put quotes (" ") around the source and destinations if they have spaces in the path. So it should be:

"c:\Program Files\whatever"

2. Lacking permissions to read the contents of the files

If you are not using Xcopy with administrator privileges, you may lack permission to read the contents of some files. Therefore, XCopy will fail to copy the files for lacking permission to read the data of a file. If you meet this problem, you can try the following two methods.

  • Save XML file to TXT files and copy them by XCopy if you can open it via Notepad or in Internet Explorer directly from the shared network folder. 

  • When you using XCopy, using administrator privileges to open files.

It seems to be good since you don't need to backup system manually. And it is able to minimize the size of backup image using incremental backup, normal compression, intelligent sector backup, and automatic splitting. But in the long run, the disk space will be fulfilled due to accumulated backups. In this case, you can choose to delete old backups manually or automatically. 

If you do this manually, based on the nature of incremental backups, it is possible that all backups between two full backups will become invalid. Thus you need to enable Backup Scheme and delete backup file automatically. You have 3 options, By quantity,  By time, By daily/weekly/monthly. You need to upgrade now (5% off for one computer) before using it. 

Enable Automatic Backup Cleanup

At the same time, you can choose to use differential backup as backup method for the scheduled task, which completely compensates for this problem with incremental backups. For differences between them, please refer to: Incremental or Differential Backup.

Besides, you still can enable email notification to confirm if the backup task is completed successfully or not. Comment, split, compress the backup image, or select a backup mode, etc.
