This can occur when there is not enough free space on the drive to which you are backing up data.
If this is not the case, the disk, CD, or drive to which you are backing up data may be write protected, or the Windows profile under which you are performing the backup may not have adequate rights or permissions to write to the drive.
Otherwise, these errors probably indicate that Ultimate Tax is unable to overwrite the file containing a previous backup in your Ultimate Tax directory. To correct this problem, you need to delete the Backup.lzh file.
To delete the Backup.lzh file
Right-click the Windows Start button, and then click Explore.
Navigate to X:\UTSxx\USERS\<username> (where X: is the drive where Ultimate Tax is installed, and xx is the tax year of your program), and right-click the Backup.lzh file.
Select Delete, and then click Yes to confirm the deletion.
If you continue to receive these errors when backing up your data, one or more files you are backing up may have become corrupted. You can work around this problem by backing up small batches of your data, or even single files at a time. If you are able to back up some files but not others, the ones causing the error have become corrupted.
This information applies to all years of the UltimateTax software.
