You only need to backup the stuff that is unique to your system as programs etc can easily be reinstalled.

Personally I backup the following

/home
/var
/etc
/usr

You need to include all files including hidden ones. Backup to an external drive formatted with a linux file system (ext4 for example) as while a FAT or NTFS system will backup your data you will lose owner, group and file permissions.

You can use the file manager for this or there are backup programs available

Can you help with this problem?
