What software do I need for remote encrypted backups?
What type of software do I need to give users access to remote encrypted backups, on both the client side and the remote?
I need something which allows the users to mount a remote encrypted volume and copy files back and from to it such as an SSHFS mounted drive, but the data should be encrypted locally before being sent, so that if the remote server gets compromised the data will be still encrypted.
I have seen raymii's post https://www.lowendtalk.com/discussion/27979/encrypted-duplicity-backups-to-openstack-swift-objectstore on using Duplicity.
If I have full and secure control of the remote server I don't mind using some software which enables the remote server to decrypt the data or at least the metadata so that file listing can be transferred across the networking, without having to transfer all the data to get file listings from it.
What other options exist like it?

What I've for personal use is an rclone encrypted mount, you might want to take a look to see if it fits your intended usage:
https://rclone.org/crypt/
@desperand @Oseri Do rclone and restic have a graphical or web interface that allow you to select versions of directories or files to restore?
Can the drives be mounted in a file browsing utility like Dolphin or Explorer, or some kind of web equivalent?
Isn't this just an encryption format?
Don't feed the troll.
Only if used twice.
(Completely) new to unix world, I see.
encrypted backups... pssh.
I don't know. I always use cli version. And yes, you can restore any snapshots what you do (from the encrypted vault) from where you store your data.

BorgBackup is cli but have a look at this thread for a tool and hosting backup solution developed by @m4nu (borgbase.com):

sshfs + encfs ?
I played with Duplicity and Borg sounds promising but in the end I just used Luks to make an encrypted partition on the backup server, and normal rsync/ssh to transfer stuff to it. There are unavoidable trade-offs between security and usability, so you have to just decide where to make them.
