Re: Set File /NoBackup

For an /IMAGE backup you cannot exclude a directory tree that way. You'd
need to mark each file in the tree /NOBACKUP.

You see, in an /IMAGE backup, BACKUP walks the directory tree and backs
up all the files there. Then at the end of the directory tree walk,
BACKUP /IMAGE goes back through INDEXF.SYS looking for files that weren't
backed up during the directory walk. It then backs those files up as well.

Even then, you will see the files in the save set and restoring the
files will recreate them, but empty.

/NOBACKUP means don't save the data. All the meta-data needed to
recreate the empty file is saved. That way when you do a backup and
restore of a system disk you don't save useless data like the
contents of a pagefile, but the new disk will have the correctly
sized pagefile.

This is, of course, a hell of a lot faster than saving and restoring
data you don't need. I used to use this on .OBJ and .OLB files in a
development tree to save a couple TK70 on my MVII. On the rare
occasion that my 3rd part disk drives let me down I restored the
disk, we ran the build procedure, and then we purged the empty files.
