Backups before upgrade 2.11

What is correct procedure to backup every folders/files before processing an upgrade?

Is a ftp copy “shop_folder” content into “shop_backup” OK?

To get “shop_backup” in operation: is it sufficient to rename respective folders?

Any other steps required? (permisions?)


I just backup my skin before upgrading.

Whenever i want to backup i use the one provided by my hosting company. that backs up all to a zip file which i download. i also back up the mysql from the hosts control panel as well.

Thank you guys!
