List of useful BTRFS tools

Hi, I want to do an "awesome things" list with BTRFS tools

Help me gather them?

Update: see here

General

BTRFS CLI Interface

btrfs-progs

official userpace utilities

BTRFS Assistant

Tool for doing many BTRFS actions graphically

It requires snapper and offers a GUI for it.

butter-manager

Tool for managing snapshots, balancing filesystems and upgrading the system safetly.

Backups & Snapshots

btrbk

Backup utility using BTRFS

Snapper

General system snapshot utility with BTRFS support, used in OpenSUSE Tumbleweed by default. There are also plugins for Fedoras dnf and for Arch pacman.

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.

Currently maintained by LinuxMint, even though they dont use BTRFS by default, it works better there.

libtuikit / transactional-update

Used in OpenSUSE microOS and the Desktop variants.

provides an application and library to update a Linux operating system in a transactional way, i.e. the update will be performed in the background while the system continues running as it is. Only if the update was the successful as a whole the system will boot into the new snapshot.

Available as a library for other distros.

Yet Another BTRFS Snapshotter

Alternatives don't supports customized of snapshot location, (e.g. Arch recommended layout). Adhering to such layouts, and rolling back using them, sometime involve non-obvious workarounds. The motivation for yabsnap was to create a simpler, hackable and customizable snapshot system.

btrfs-autosnap

There are 2 separate projects with that name

grub-btrfs

Set BTRFS snapshots as boot options

[btrfs-sxbackup])https://github.com/masc3d/btrfs-sxbackup)

Incremental btrfs snapshot backups with push/pull support via SSH

Small CLI tools

btrfsd - tiny Btrfs maintenance daemon

Btrfsd is a lightweight daemon that takes care of all Btrfs filesystems on a Linux system.

It can:

  • Check for detected errors and broadcast a warning if any were found, or optionally send an email
  • Perform scrub periodically if the system is not on battery
  • Optionally schedule balancing operations as well

dupreremove

Tools for deduplicating file systems

compsize

Takes a list of files on a btrfs filesystem and measures used compression types and effective compression ratio

Used in flatpak-dedup-checker

btdu

sampling disk usage profiler for btrfs For multiple reasons, classic disk usage analyzers such as ncdu cannot provide an accurate depiction of actual disk usage. (btrfs compression in particular is challenging to classic analyzers, and special tools must be used to query compressed usage.)

btrfs-list

Helps listing directories

btrfs-fuse

A read-only btrfs implementation using FUSE (Filesystem in Userspace). Although btrfs is already in mainline Linux kernel, there are still use-cases for such read-only btrfs implementation:

btrfs debugger

The btrfs debugger (pronounced "buttered").

btrd is a REPL debugger that helps inspect mounted btrfs filesystems. btrd is particularly useful in exploring on-disk structures and has full knowledge of all on-disk types.

ntfs2btrfs

a tool which does in-place conversion of Microsoft's NTFS filesystem to the open-source filesystem Btrfs, much as btrfs-convert does for ext2. The original image is saved as a reflink copy at image/ntfs.img, and if you want to keep the conversion you can delete this to free up space.

Consists of a Windows and a Linux executable. Does not work on the primary drive.

WinBTRFS

filesystem driver for Windows

Partition managers with support

  • KDE-Partitionamanger
  • GNOME-Disks
  • blivet-gui (Fedora Anaconda setup)
  • gparted ?

Data recovery

When having deleted or corrupted data on a BTRFS partition, these tools can help:

Testdisk?

  • photorec?

Scalpel?

R-Linux

Freeware, not FOSS? Not related to R and "R-Studio" is also not related to RStudio

BTRFS bindings

These allow you to do BTRFS actions in many programming languages
