Spinbackup, a cloud-to-cloud backup tool for individuals
It allows to back up the data from my Google account in Gmail, Google Drive, Google Photos, and other Google products. Spinbackup also supports personal Google accounts for individual use, is affordable, and lets me access the data even if I lose access to my Google account (don't take this feature for granted).
The product has a few rough edges though. Two-step verification comes with no backup codes. And there's no way of updating a payment method, other than canceling a subscription and purchasing it again with a different method.
