Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Duplicity
For starters it has a tendency to paint itself into a corner on ENOSPC situations. You won't even be able to perform a restore if a backup was started but unfinished because it ran out of space. There's this process of "regressing" the repo [0] which must occur before you can do practically anything after an interrupted/failed backup. What this actually must do is undo the partial forward progress, by performing what's effectively a restore of the files that got pushed into the future relative to the rest of the repository, which requires more space. Unless you have/can create free space to do these things, it can become wedged... and if it's a dedicated backup system where you've intentionally filled disks up with restore points, you can find yourself having to throw out backups just to make things functional again - even ability to restore is affected.
That's the most obvious glaring problem, beyond that it's just kind of garbage in terms of the amount of space and time it requires to perform restores. Especially restores of files having many reverse-differential increments leading back to the desired restore point. It can require 2X the file's size in spare space to assemble the desired version, while it iteratively reconstructs all the intermediate versions in arriving at the desired version. Unless someone fixed this since I last had to deal with it, which is possible.
Source: Ages ago I worked for a startup[1] that shipped a backup appliance originally implemented by contractors using rdiff-backup. Writing a replacement that didn't suck but was compatible with rdiff-backup's repos consumed several years of my life...
There are far better options in 2024.

Trying to install rdiff-backup on an Oracle Cloud Red Hat VM.
and that should install the latest version, rdiff-backup-2.2.4-2.el8.x86_64.rpm. This is all described in the rdiff-backup README file.

How do I copy data from one HDD to another using Linux Mint?
Rdiff-backup - close to what you do currently but at least provides versioning. Based on rsync

Accomplishing What I Want With What I Have
as in just a copy of your files? This I would barely consider a backup, more of just a mirror from a point in time. What're you missing by doing this? versions of files, deduplication, and encryption (last one being very important for the best kind of backups, which should be off-site). Just because it's not files doesn't mean it's proprietary. Proprietary would mean secret and undocumented. There are many great options. Borg is my favorite but Kopia is probably better if you use windows, urbackup is an option if you want centralized management of backups and rdiff-backup is if you want something kinda what you have currently but adding versioning but lacks deduplication and encryption.

Backup software recommendation
If you're comfortable with the cli and you want to have your backup in a plain file format with some incremental backups, there's rdiffbackup. It uses rsync under the hood and has worked quite well for me.

Name a program that doesn't get enough love!
Rdiff Backup - Reverse differential backups that uses rsync, linking, and can tunnel via ssh. You get a full current backup with increments available to restore any version of the file with minimal storage space used.

BorgBackup, Deduplicating archiver with compression and encryption
borg is great. we've been using it for the past 3 years to archive hundreds of file-level backups of servers, database dumps and VM images. average size of each borg repo is few GB but there are few outliers up to few hundreds of GB.
borg replaced https://rdiff-backup.net/ for us and gave:

Advice for Automated Copying of my Off Grid 6TB Media Hoard :)
Robocopy is great if you don't have access to rsync. If rsync via WSL2 for instance is an option, I'd personally go with rdiffbackup.
- Do incremental backups generally store only the delta of each file change or the entire new file?

BorgBackup, Deduplicating archiver with compression and encryption
I tried a few backup tools and https://github.com/andrewchambers/bupstash is my favorite by far but it's not that well known.
It was pretty fast already and recently got multithread support. It has been the only thing usable for backing up a few TB in a raspberry for performance reasons.
Keep in mind it's relatively new and the author does not yet recommend to use in production as the only backup solution.

Encrypted Backup Shootout
bupstash (rust) - https://github.com/andrewchambers/bupstash
The authors bupstash[1] tool looks interesting.
I see there's an issue made for Windows support, how is that with Rust?
Unless it's doing low-level stuff like directory monitoring I assumed Rust would be quite portable?

What's everyone working on this week (53/2020)?
Benchmarking my backup tool that was written in rust: https://github.com/andrewchambers/bupstash . Rust did not disappoint when it comes to performance, it seems to beat restic by a factor of 2x-200x depending on the benchmark.
What are some alternatives?
BorgBackup - Deduplicating archiver with compression and authenticated encryption.
kopia - Cross-platform backup tool for Windows, macOS & Linux with fast, incremental backups, client-side end-to-end encryption, compression and data deduplication. CLI and GUI included.
restic - Fast, secure, efficient backup program
Bup - Very efficient backup system based on the git packfile format, providing fast incremental saves and global deduplication (among and within files, including virtual machine images). Please post problems or patches to the mailing list for discussion (see the end of the README below).
Rsnapshot - a tool for backing up your data using rsync (if you want to get help, use https://lists.sourceforge.net/lists/listinfo/rsnapshot-discuss)
syncthing-android - Wrapper of syncthing for Android.
Duplicity - Unnoficial fork of Duplicity - Bandwidth Efficient Encrypted Backup
tarsnap - Command-line client code for Tarsnap.
