If your dumps are so small they will fit on CD-R, you could do the
following:
- make a dump
dump -0 -a -L -f - /usr |gzip -c >usrdump.gz
- use mkisofs to make an ISO file containing your dump
mkisofs -r -pad -o usrdump.iso usrdump.gz
- burn the ISO to CD-R with cdrecord or burncd.
If the gzipped dump file is larger than a CD, you could use split(1), to
make CD-sized chenks, and burn them to different CD's.=20

If you want to use a CD as a kind of harddisk, you could use an UDF
filesystem. See udfclient in ports.
If the dumps are big, upgrade to a DVD burner and use growisofs(1) to
burn the data to DVD.
