I have Joomla (CMS) in Apache Wamp Server in my local pc. I want to know how to get backup from my pc and how to use that backup in another pc in wamp server. simple copy paste is not working in different PC. Thanks in advance.
What errors are you receiving? Have you copied all Joomla files as well as backed up the database and configured database user names passwords correctly on the other computer?
just copy all files across. zip em up and unpack on other server. also. export the data from the MySQL db. depending on the paths etc, you may have to change or edit some strings.
