SYMPTOMS
This information applies to both Microsoft DoubleSpace and Microsoft DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and filenames.
If you try to back up to a DoubleSpace-compressed floppy disk using Microsoft Backup or Microsoft Backup for Windows, you receive the following message:
NOTE: If you choose "MS-DOS Drive and Path" instead on drive A or drive B, you receive the message "insufficient disk space in <drive letter>: Backup to DOS path cannot be completed."
CAUSE
Microsoft Backup writes over your DoubleSpace-compressed floppy disk, making it an uncompressed disk.
Since Backup compresses data, there is no benefit to writing compressed data to a compressed disk. Once the data has been compressed once, it cannot be compressed again.
WORKAROUND
You may be able to work around this problem by choosing MS-DOS Path for your destination.
