My reading is that using --force on a restore will overwrite existing
files with the same name - so you may lose previous data at the restore

repository) it is logical to use a clean destination, in which case it
shouldn't be a problem.

Anyone know different?

When you are restoring a directory, "--force" will not only overwrite
existing files (which is probably what you intended, anyway), but it
will also _delete_ any files or even entire subdirectories that were
not present in the backup.  It will restore your directory to exactly
the state it was on the backup, nothing more, nothing less.  That
might be a nasty surprise.

Thanks for the info. That is logical, but I wasn't aware of it.
