Determining Which Files to Back Up When You Use DoubleSpace (98459)
The information in this article applies to:
- Microsoft MS-DOS operating system 6.0
- Microsoft MS-DOS operating system 6.2
- Microsoft MS-DOS operating system 6.22
This article was previously published under Q98459 SUMMARY
When you use DoubleSpace, you should back up the files on your
compressed volume, not the compressed volume file (CVF) on the host
drive. For example, if you have compressed drive C and DoubleSpace has
created the host drive as drive H, you should back up all your files
on drive C and any data files left on drive H. You do not need to back
up any DBLSPACE.<nnn> files (for example, DBLSPACE.000) on the host
drive.
This allows you to restore single files from drive C if necessary. If
you back up only the DBLSPACE.<nnn> file(s) you can restore only an
entire drive. This could be a problem because all changes to all files
(on the compressed drive) since the last backup are overwritten when
you restore the DBLSPACE.<nnn> file.
For more information on DoubleSpace terminology, run DoubleSpace,
choose Contents from the Help menu, and then select Understanding
DoubleSpace Terms.
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.
