duplicity vs MEGA

Data is encrypted locally before being sent, and kept encrypted by a key that is never stored on the remote machine. So you might even store your data on a public space, people would still need your key or brute force it.

Duplicity uses the rsync algorithm so only the changed parts of files are sent to the archive when doing an incremental backup. For instance, if a long log file increases by just a few lines of text, a small diff will be sent to and saved in the archive. Other backup programs may save a complete copy of the file.

You can retrieve older versions or files you recently deleted locally even after having updated your backup.

Duplicity does not make many demands on its archive server. As long as files can be saved to, read from, listed, and deleted from a location, that location can be used as a duplicity backend. Besides increasing choice for the user, it can make a server more secure, as clients only require minimal access.

Docker allows to run programs on any Linux without having to really install them, and allows to manage versions so it runs exactly the same on different machines.

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.
