Looking for a backup software for backup to sync to backup on AWS S3 and Google Drive with the option to do differential uploads, instead of uploading all the files all the time
Try FreeFileSync.
I use it to backup my project files to GDrive
Time Machine is the only complete backup solution. Third party apps won’t backup your passwords, 2FA codes, app-data etc. Unfortunately iCloud is the only way for accessibility on the go. The other option is to issue SMB shares through a NAS. Both are differential and fast but later needs more upfront cost, though cheaper in the long run.
Alternatively you can also create a sparse bundle image on the local google drive/onedrive folder. Then mount it inside the Time Machine. It’ll also be differential but increase TBW wear on your Mac.
Just ensure that online sync is paused during backups, or else your data might get corrupted.
What you are looking for is snapshot backups where old snapshots are maintained.
For offline system backup I have been using timeshift for a long time and it works well offline.

Duplicacy, Arq Backup. Both wonderful options.
I think i wasn’t clear, my bad, i need to backup my image library, nothing to do with system image. Purely data files
yes i checked, but i also need aws s3 as it is my primary, only looking for gdrive as it is offered as free from jio for certain period, however long term cost is high.
Are there any other tools???
Duplicacy does exactly what you are asking. You can just use rclone as well.
zerobyte with restic backend connected to rclone, has all the bells and whistles
