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.

I accidentally programmed my server to back up all files... even backups
That's still easier using snapshots and something like btrbk. Snapshot the directory at start, prune if there are too many snapshots (or snapshots get too old).

Ur best backup software
I'm on Arch, but you might still find it useful: Btrfs snapshots Arch Wiki - Incremental backup to external drive GitHub - btrbk
- Deduplication how to?
-
Fast and comprehensive system backup. Can Linux software do it?
the smoothest backup tool i have seen for Linux is btrbk works real nice and is customizable for almost all use-cases BTRFS rocks :)

Trying to understand the real impact of not having ECC
I recommend redundancy and regular verification is you want to insure your data against corruption. If you do that, you can forget about things like ECC. My setup is a NUC server running Ubuntu with a USB3-connected storage drive running BTRFS. I use btrbk to auto-snapshot and auto-replicate via incremental sends to my BTRFS backup drive, and RotKraken to track integrity of the data with a monthly verification run so that I notice corruption in time to correct it.

BTRFS snapshots and btrbk as a backup solution
In pondering my backup strategy, I was wondering if I could use BTRFS snapshots and a backup tool like btrbk, which is a nice integrated snapshot/backup solution I've used happily on desktop Linux. BTRFS needs subvolumes for snapshots, so I couldn't backup the host itself (which wasn't installed with a / subvolume like other distributions I've used), but it could snapshot the VMs and containers, which have their own individual subvolumes. Then btrbk can send that snapshot in an incremental fashion to external storage.
-
btrbk: subvolume has no UUID error
I then installed btrbk and tried to follow the instructions to create snapshots of root and home on the SSD and then send/receive those to the HDD. I mainly used https://github.com/digint/btrbk and https://mutschler.dev/linux/fedora-btrfs-35/, but I don't use luks.

The various scripts I use to back up my home computers using SSH and rsync
For anyone using btrfs on their system, I heartily recommend btrbk, which has served me very well for making incremental backups with a customizable retention period: https://github.com/digint/btrbk

incremental snapshot backup tool: which one should i go for?
btrbk is the best solution I know.
-
how do you Backup your system?
I use BTRBK to make and copy the BTRFS snapshots to my HDD. I schedule it to run every 3 hours using a Sytemd unit file through my own script to avoid running the backup at inconvenient moments:

Question about snapper
You might be interested in snap-sync. It is a bash script which accomplishes btrfs backups using snapper under the hood. So no need to use btrbk (but you get all the same functionality).

Backup strategy
I've been using snapper and snap-sync for automated snapshots and backups to an external drive. Recently, snap-sync is no longer maintained, and it may not be able to do some more things that I want to do, such as:
-
How to replace snap-sync?
I was actively using snap-sync to back up my files to a local hard drive. Unfortunately, snap-sync will be retired soon.
-
Reinstalled my F35 to BTRFS, looking for your thoughts and opinions for snapshot/backup solutions
I use snapper for snapshots and snap-sync for backing up said snapshots on an external drive.
-
"Install once, update forever"?
Yeah, I use snapshots for backups using snap-sync, which is a convenience script around btrfs send. Personally I use it to back up onto an external HDD, but it can also do remote backups over SSH. I'm just not sure if remote backups are incremental or not.
-
Let's talk about Btrfs.
On my laptop I make extensive use of openSUSE's snapper and the snap-sync script to sync to two external USB drives. Lastly, I wrote a script to clean/expire snapshots on the external volumes.
-
Have some question before moving to Fedora, hoping you guys can help
Snapshots aren't proper backups by themselves; they don't protect you from disk failure or the entire filesystem somehow being corrupted. It is possible to use them as backups; personally I use a command-line script called snap-sync to do this. This has the advantage of retaining the incremental nature of snapshots (though the incrementality will be on your backup media, so the first snapshot of a 100GB filesystem you put on your backup drive will take up 100GB of space), plus it integrates nicely with Snapper which is the snapshot utility I use.
What are some alternatives?
snapper-gui - GUI for snapper, a tool for Linux filesystem snapshot management, works with btrfs, ext4 and thin-provisioned LVM volumes
snapper - Manage filesystem snapshots and allow undo of system modifications
TimeShift - System restore tool for Linux. Creates filesystem snapshots using rsync+hardlinks, or BTRFS snapshots. Supports scheduled snapshots, multiple backup levels, and exclude filters. Snapshots can be restored while system is running or from Live CD/USB.
grub-btrfs - Include btrfs snapshots at boot options. (Grub menu)
zfs - OpenZFS on Linux and FreeBSD
bees - Best-Effort Extent-Same, a btrfs dedupe agent
BorgBackup - Deduplicating archiver with compression and authenticated encryption.
linux-timemachine - Rsync-based OSX-like time machine for Linux, MacOS and BSD for atomic and resumable local and remote backups
buttersink - Buttersink is like rsync for btrfs snapshots
