I am running Android 11 on a Samsung Galaxy A70. I am unable to change the backup frequency from my phone to Google drive or Samsung Cloud. Both are preset at 24 hours. I want to change the preset to a more longer duration. I recently noticed that my call log was gone. By the time I noticed it was gone, it was too late. My phone had already run a backup and had over written the old backup with the call log I needed. Also, is there a way to keep multiple backups on the cloud? That might help as well.
