It looks like the default is dom0. (Not sure, since I usually use the
CLI, but I just tried going through the first few prompts in the GUI,
and the default target was dom0.)

Yeah, it sound like you probably have ~500GB worth of backups in your
dom0 home directory. You'll probably want to move those to another
location before backing up dom0 (if you don't want to include those
backups in your backup).

I recommend making frequent backups (so that you don't lose data in an
unexpected hardware or software malfunction), not just for migration.

That really depends on you. The answer will be different for different
people. The main consideration is whether you have any data in dom0's
home or in your TemplateVMs that you don't want to lose. Personally, I
would back everything up just in case. You may not end up using it all
in the migration process, but the problem is that you may not be
entirely certain, before that process is complete, which data you will
want to have migrated. In hindsight, you may wish you had migrated
more. You can always exclude data you have, but you can't include data
you no longer have.

Again, it really just depends on what data you want to keep. Given
your uncertainty, I highly recommend backing up *everything* so that
you don't regret losing something later. It sounds like you're talking
about less than a terabyte in total, which is a pretty small amount of
data relative to hard drive capacities these days. Better safe than

It would be some large directories in /var/tmp that start with
`restore_`. But it sounds like that's not your problem. Pretty sure
it's what we diagnosed above (large backups in dom0 home).
