Does a backup overwrite current data on phone?

[commonman]

A backup/restore question. I have three phones A, B, C. A (most recent PREVIOUS phone, Samsung s8+), B (old phone, Samsung s7), C (new phone, Samsung s8 actuve). I have restored the backup from A to C using my Google account and plan to continue this method. I have found legacy data residing on B that I wish to port to C (contact, sms, downloads, audio, apps). If I backup B will the restore to C overwrite data or will it simply add the data from B to C rather than overwriting the data currently on C? Thanks for working on my puzzle?

Why don't you use Samsung built in cloud back up or smart switch? Much more things you can do over Google's back up

I will try that. Now, back to my question.....does a restore completely overwrite previous data. I wish to keep my current data and ADD additional data from another phone source. Can I ADD without OVERWRITING? My best analogy would be like synchronizing. Yeh, that's what I want to do....synchronize my phone with another phone. Can it be done?

If you use a otg adapter with cable between phones should add data not remove existing data

But if you do what I I mentioned between Samsung phones it will work flawlessly , I have pretty good experience in this
