What's the best way to back up the complete contents of my phone?

What's the best way to back up the complete contents of my phone? I am about to replace my A70 and am worried that some items might be lost in the process of transferring data. I tried backing up my phone to my laptop, using SmartSwitch, but although the laptop has 30% of its memory free, SmartSwitch indicated "insufficient memory space".

Hello 👋 @Byxelkrok 

My personal choice is 

• Back up to Samsung Cloud but this will not back up your Gallery. 
• My Photo's are Backed up to Google Photo's but a person can use OneDrive or Dropbox etc. 
• I then only use Smartswitch to move my Gallery. 

This process means I have never lost any contents.
