Google Cloud Storage vs MEGA

Same price a Google Drive, but more flexible as you pay for what you use (Google Drive you have to jump from 100 MB to 1 TB for example). Also supports larger backups.

Versioning can be enabled at no extra cost so you may retrieve older versions or deleted files.

duplicity allows to encrypt data locally using GPG and it supports Google Cloud Storage.

Via the Google Cloud Platform or their CLI tool, you can create publicly accessible URLs to parts of your data.

Linux, Windows and Mac.

All files uploaded to Mega are first encrypted on the users side. To access files a decryption key must be supplied. For ease of use, the decryption key can be appended to the URL you share.

50 GB trial for new accounts after registering for a month, then 15 GB. There's also three upgrade plans, starting at 500GB and $110/yr. 15GB may not seem much, but Dropbox only offers 2GB for the free plan. This is better than Google Drive because Google Drive storage is shared with all the Google services you are using.

Just drag and drop files in the browser window, then create a link for sharing. You will need an account to create a link. To streamline the process for new users you can start uploading as soon as you access the website and create an account while it's uploading.

They will never look through your files unless they ask for permission.
