I believe it almost never happens. As I understand the card association rules, the merchant has to hang on to the data for refund purposes.
Nope, all you need to generate a refund is the original transaction ID. At least with the processors I use. You can get the PCI requirements here: https://www.pcisecuritystandards.org/security_standards/pci_dss.shtml You are allowed to store the Card number, name and expiration date. Appendix B allows you to store that unencrypted. You are not allowed to store the mag stripe, CVC2 or PIN.
