To "back up" something has two meanings
In the context of information
1) To provide evidence which proves that the information is true.
e.g "It's interesting what you're saying, but can you back any of it up?"
2) To create a copy of the information, in case the original is lost or destroyed.
e.g "You need to make sure you back up all of your research data."
In the context of people it means to provide assistance to someone who is in a conflict, in order to help them win that conflict.
e.g "No one believed my friend at first, but once I backed her up, people realised she was telling the truth"
"Hey, why didn't you back me up?"
Note the word order.
Back me/you/him/her/it/them/NAME up (Not Back up SOMEONE)
Back up SOMETHING/ Back SOMETHING up (both are fine)
Backing up.
Backing up information refers to making copies of data files or resources to prevent data loss in case of hardware failure, human error, or cyber attacks. This can involve storing data on external drives, cloud services, or other storage media to ensure that information can be easily recovered if the original files are lost.
In some things like math and arguements, you can prove it by backing it up or checking it. In other things, look up information.
