This is not true. RSJ implements an IFS. Once you attach a drive, it has
a drive letter. You should be able to open up the drive in the drives
folder and drag files and folders to it. This is why it's a good test of
the RSJ setup.

Possibly. You might have been forcing the drive to operate to too hight a
speed. Check your settings. Unless you have a bad drive or a bad CD-RW,
this should work just fine.

This is how most CD writing software works. It's not a temp file, per se.
It an exact image of the data that will be written to the CD. It is
called an ISO image. RSJ probably did it this way because it's easier to
write the software.

If you use mkisofs and cdrecord, the ISO is optional. Because they are
unix apps written in unix style, one can pipe the output of mkisofs
directly into cdrecord. This works fine as long as the rest of the
hardware is fast enough to keep up with the CD-R. This is not so easy
because building the ISO so that it can be passed in block order from
mkisofs to cdrecord is a compute intensive task.

You'll get the typical disk full error when you run out of space. The
result will be a coaster. Just write yourself a backup checklist and use
it.

Sure. They are files, just like any other files.

You can do this, but the BST files are not used for restores. The
catalogs are used. Catlogs can be large, so you probably want to delete
the old ones. You can always recover a catalog from the backup.

Don't forget to do a test restore. Just restore the files to some other
location. If you are using spanned CD's, make sure you can recover from
them. Some folks claim to have problems. I don't know if this is a
general problem or not. Better to test before you really need the use the
backup.
