Hi Jiri,
I recomend to you to ask your Symantec Partner to give you CD with BE SR 6.5 (current version 6.5.2) - with CD you can use and test product for 30 days without licenses. If you want to test Restore Anywhere functionality, then you will need trial licenses that you can also get from your Symantec Partner and with trial licenses you will have 60 days to test it.
If you do not have preffered Symantec Partner, then you can look for them in your area using Partner Locator:
