Notes and Suggestions
• Unless otherwise specified, the old files on a backup floppy's
root directory are erased before new files are added.
• If more than one diskette is required, BACKUP prompts you
to exchange diskettes when the current diskette is full.
• If you try to backup a shared file that you do not have access
to,
PATHNAME\FILENAME.EXT Not able to backup at
t
his
t
1
me
is displayed.
• BACKUP files contain control data, and are not usable.
• BACKUP exits with ERRORLEVEL set as:
o -
Normal completion
1 - No files found to backup
2 - Some files not backed up due to file sharing conflicts
3 - Terminated by {Ctrl-Break}
4 - Terminated by error
• If the target is a fixed disk, the backup files will be placed in
a subdirectory named \ BACKUP. If the target is a floppy,
the files are placed in the root directory.
• The source disk should not be write-protected.
