Does Clonezilla is open source?

"Clonezilla is a suite of open source drive cloning" is the definition of Google. Well, the answer is not clear to me.

I want to save and restore images using Clonezilla via AWS S3 bucket, in order to accomplish this task I have to use S3fs, and add my AWS credentials every time I perform an action. Repetitive and annoying.

My question: does someone have experience configuring t开发者_Go百科he credentials already via Git repo as a secret? or anything that could help with this situation?

Thanks for your help!!
