I know I can backup a full account (mail + address books + Calendar) for a single user using:
/opt/zimbra/bin/zmmailbox -z -m user@domain.com getRestURL “//?fmt=tgz” > /tmp/account.tgz

and restore it with:
/opt/zimbra/bin/zmmailbox -z -m user@domain.com postRestURL “//?fmt=tgz&resolve=skip” /tmp/account.tgz

Which would be the correct lines for calendar or address backups/restores?

thanks!
