			        BACKUP AND RECOVERY

Commands that you can use to prepare for future problems (by backing up
the files on your hard disk to diskette), see if there are problems on your 
disks, and perform simple recovery from those problems. Even when these
can't recover, separately purchased programs can often correct the problem. 

 DOS COMMAND	WHAT IT DOES

    BACKUP	makes a copy of precious files on your hard
		disk on diskettes or another hard disk.
    CHKDSK	reads some of the directory information on a
		disk to see if it looks OK. Can also recover
		limited amounts of lost data. Can provide an
		early warning of pending disk problems.
    RECOVER	reads a file, and tries to save the parts of 
		it that are still good.
    RESTORE	reads those precious copies of your files from
		the disks BACKUP wrote.
    REPLACE*	makes a copy of precious files on another disk,
		but any program can read them, not just RESTORE.
