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.

-
Rollback a root snapshot without rescue media
Then you need a service that will check snapshots folder and automatically create boot entries. I have refind-btrfs, which does exactly that.
-
Is GRUB or Systemd-boot better for BTRFS?
rEFInd can also be used to boot into Btrfs snapshots using this automation tool.
- Using snapper with rEFInd or systemd-boot (BTRFS)
-
grub broke, again!
Yes, see refind-btrfs
-
Is grub still worth using or should I switch to refind/sysmd?
It's a actually third party tool which simply automates the whole process because enabling such a feature manually is pretty cumbersome and annoying.
-
Arch on Btrfs is a perfect match!
In a similar vein, there's also https://github.com/Venom1991/refind-btrfs.
-
which bootloader should I use after the grub incident ?
Especially when using refind-btrfs. "This tool is used to automate a few tedious tasks required to boot into Btrfs snapshots from rEFInd. It is to rEFInd what grub-btrfs is to GRUB.". It works great.
-
Systemd-boot with btrfs snapshot boot?
Well.. The same way GRUB has grub-btrfs, rEFInd has refind-btrfs, which automates the whole process of booting your snapshots. Maybe you could give rEFInd a try. And honestly, I don't think that the GRUB issue will happen again. I'm using Linux for ages and it's the first time I saw it messing stuff up. Sorry if not answers your questions directly.
-
So why do so people still use GRUB?
Like GRUB has grub-btrfs to automate this process, refind has refind-btrfs. I never tested grub-btrfs, but refind-btrfs is awesome.
-
What's the best way to create and restore BTRFS snapshots?
I'm using snapper with refind-btrfs. The setup was confusing at first but now it works nicely.

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:
What are some alternatives?
