Description
The git borg linker utility (abreviated as gblk) is a tool that aims to ease the usage of borgbackup in a project using git as a version control system.
It helps you to track the changes in your results folder every time you commit a change in your code. For versionning your results gblk uses borgbackup a tool to create backups and using a data deduplication technique.
Prerequisites
To install gblk, git and borgbackup must be installed on your system.
To install borg, you can go to borg’s installation page.
As gblk is written in rust, you need to install it with:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
You can optionally install delta. Delta aims to show differences between two files and can be used with git. It can be customized by editing the ~/.gitconfig
file. This tool is needed if you use the --diff
option of the gblk mount
command.
You can optionally install ImageMagick. ImageMagick aims to perform various operation on images. This tool is needed if you plan to create diff of image with gblk with the --diff
option of the gblk mount
command.
If you want to share your borg folder whith gblk clone
, push
and pull
, rsync
must be installed on your computer and on remote machines where you want to store/share you results. ssh
program must be installed to send the archived results to remote servers.
Below some commands you can use to install gblk dependencies on ubuntu:
# Install git
sudo apt install git
# Install borg
sudo apt install borgbackup
# install rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# Install delta (Ubuntu)
wget https://github.com/dandavison/delta/releases/download/0.15.1/git-delta_0.15.1_amd64.deb && \
dpkg -i git-delta_0.15.1_amd64.deb
# Install Imagemagick
sudo apt install imagemagick
# Install Rsync (if not already installed)
sudo apt install rsync
# install gblk
cargo install --git https://gitbio.ens-lyon.fr/LBMC/hub/git_borg_linker
# Update your bashrc
echo "export PATH=$PATH:$HOME/.cargo/bin" >> ~/.bashrc
source ~/.bashrc
Installation
To install gblk run the following command:
cargo install --git https://gitbio.ens-lyon.fr/LBMC/hub/git_borg_linker
Usage
gblk is meant to be used inside a project using git as a version control system. It will only be helpful if your projet folder contains a .git
folder. A results
folder must be present in your project directory as gblk will try to backup it.
To sum up gblk must be used in a folder having this minimal structure:
project
├── .git
└── results
To display the help of gblk run the following command:
$ gblk help

$ # The next command is important: it will check if your results folder doesn't contain new results compared to your archive with the current git id. If there is no errors, then you wont lose any data

$ gblk co --mode hard # hard is used to delete file that were not present in the first commit. Otherwise only existing files at the destination commit will be updated.
$ ls results
result.txt
Not: if gblk pre-co says that you might lose data compared to the saved version of your actual commit, then use gblk commit --update
.
Example usage with git hooks
Git hooks are commands that can be automatically executed before and after some git commands. They are defined in the repository .git/hooks
.
gblk can create two hooks:
post-commit
hook that executesgblk commit
after every git commitpost-checkout
hook that execute:git co
to revert back to the last commit as a pre-checkout hooks doesn’t exits.gblk pre-co
to be sure to not lose any data before the actual chekoutgit checkout
do the actual chekoutgblk co
to revert back to the results folder corresponding to your target commit
As the pre-checkout
hook doesn’t exits, this is the post-checkout
hook that is used to cancel the first checkout and check for data loss.
When gblk creates hooks it also modifies the .git/config file
to add 3 aliases:
- alias
co
: Performs a quiet checkout. This alias is used in step1 of the post-checkout hooks, so it is recommended to use it when you perform a checkout. It allows to have a quiet initial checkout that is then quietly reverted so gblk can check that no data is lost. - alias
conh
: This alias performs a checkout without thepost-checkout
hooks. This can be usefull when you perform a checkout to a deleted commit on your.borg
archive. If you want to checkout to another commit, gblk pre-co will prevent that because it will think that the results folder was not commited withgblk commit
. To perform a checkout anyway you can use:git conh [TARGET-BRANCH] && gblk checkout --mode hard
- alias
cnh
: This alias performs a commit without using thepost-commit
hooks.

mount command
Gblk as two commands mount
and unmount
that can be used to respectively mount your borg archives into the .mount
folder of the project directory or unmount them.
When the borg archive is mounted, borg is locked ! It means that you can get the following error message if you forget to unmount a borg acrchive when calling a borg command on it: Failed to create/acquire thelock ..
.
To resolve it just use gblkt umount
. gblk will silently unmount the borg archive before commit
, checkout
, pre-checkout
and mount
commands.
gblk mount usage:
gblk-mount
Mount an old file/directory from one or multiple archive named afert git commits into the .mount
folder inside de project directory
USAGE:
gblk mount [OPTIONS]
OPTIONS:
-c, --commit <COMMIT>
Commit name, sh: Glob is supported. This is an optional parameter: if not set then all
commit archives will be mounted into the .mount directory
-d, --diff
Displays the differences between two files mounted corresponding to the given path.
Note that if only one file is recovered then, the other is taken from the current result
folder
This option is deactivated when used with --diff
-h, --help
Print help information
-l, --last <LAST>
Consider last N archive after other filter were applied
-p, --path <PATH>
The file/directory to extract. This is an optional parameter. If not set then all files
in the archive will be displayed
-v, --versions
If set, displays the .mount directory in 'version view'.
- Normal view: The `.mount` directory contains a subfolder with the name of archives.
- Version view: The `.mount` directory contains the results folder and every file within
it becomes a directory storing every version of that file
Examples:
$ gblk mount # mount all archives in `.borg` into `.mount` folder
$ gblk mount -v # mount all archives in `.borg` into `.mount` folder in version view.
$ # It is not necessary to execute "gblk umount" before the above command because its run silently before "gblk mount"
$ gblk mount -c '[ab]*' # mount all archives named after commits strating with 'a' or 'b'. Note that the quotes are necessary for -a options
$ gblk mount -c 'ae8rt77*' -p 'results/fichier.txt' # mounts all files matching 'results/fichier.txt' inside archives named after commits starting with'ae8rt77*'
$ gblk mount -p 'results/**/*.txt' # mounts all txt files inside every archives
$ gblk mount --last 2 # mount the last two archives named after the last commits
$ gblk umount # unmount the archive mounted into `.mount` directory
If we have two archive containing a file named file.txt
and we want to direclty compare them in a similar way as git diff
, then we can enter:
gblk mount -p 'results/file.txt' --diff
The differences between the two files will be displayed with delta:
Δ .mount/cfdc/results/lol.txt ⟶ .mount/4ec196bb/results/lol.txt
────────────────────────────────────────────────────────────────────────
─────┐
• 1: │
─────┘
│ 1 │newblooup │ 1 │newblooup
│ 2 │dfbifbsi │ 2 │dfbifbsi
│ │ │ 3 │obeigbvisdb
If only one file matches the path given with the --path
argument of the mount
command, then, gblk
will search if a match can be found in the current results
folder.
Learn how to customize delta display by going here
You can also display the differences between images. To be able to do so, imagemagick must be installed.
If you plan to make pdf diff, you might want to change imagemagick /etc/ImageMagick-[VERSION]/policy.xml
and replacing the line:
policy domain="coder" rights="none" pattern="PDF" /> <
by
policy domain="coder" rights="read | write" pattern="PDF" /> <
Currently the following formats are available for an image diff: PNG, JPEG, BMP, ICO, SVG, PDF
Let’s say, we have one image named im1.png inside the last commit. to compare it with the image im1.png in the result folder, you can type:
gblk mount --last 1 -p 'results/im1.png' --diff
The diff image will be created inside the .tmp
directory of the project folder.
borgignore file
Its possible to tell borg to ignore files in the results folder. To do that, you can create a .borgignore
file at the root of the project directory.
To ignore a given file named file.txt
you can add to your .borgignore
file the following content:
- results/file.txt
- You have to put a
results/
prefix in front of your files. - To exclude a file, the line must begin by
-
.
To ignore every files named file.txt wherever they are, use the following syntax:
- /**/file.txt
You can also ignore files with a given extention inside a folder (named folder
here) with:
- results/folder/*.txt
To ignore all files with a given extention use:
- /**/*.txt
To rescue files from being ignored by another pattern, you can use a line begining by +
in .borgignore
file. Example: If we have a test
folder inside the results
folder containing the files a.txt, b.txt, …, z.txt and we want to ignore everything except the c.txt file. This can be done with:
- results/test/*.txt
+ results/test/c.txt
Delete command
This command is a wrapper of the borg delete command. If you need information about the borg delete
command, you can check borg’s documentation
This command can be used to delete specific archive directly by their name or by a prefix or a glob
This command doesn’t actually free disk space. You have to use gblk compact
afterwards to achieve this
gblk delete usage
To display the help of gblk delete, run the following command:
gblk delete -h # -h for compact help, --help for a more exhaustive help
To see what archive you are about to remove, enter
gblk delete --list --dry-run [OTHER_OPTIONS]
- The
--dry-run
option will keep the archive unchanged - The
--list
option will display what was deleted (without--dry-run
option) or what would be deleted (with thedry-run
option)
Prune command
This command is a wrapper of the borg prune
command. Check borg’s documentation for more details.
This command can be used to keep archives created during a given period of time and remove others.
This command doesn’t actually free disk space. You have to use gblk compact
afterwards to achieve this.
gblk prune usage
To display the help of gblk prune
, run the following command:
gblk prune -h # -h for compact help, --help for a more exhaustive help
To see what archives you are about to remove, enter
gblk prune --list --dry-run [OTHER_OPTIONS]
gblk compact
This command frees .borg
repository space.
You can use this command after deleting one or more archives because it will really free repository space.
To use this command, you can run:
gblk compact # -h for compact help, --help for a more exhaustive help
To compact you .borg
folder, you can run
gblk compact --verbose
If the amount of parts that need compaction is big the .borg folder
, this command may take a while. Consider using the --progress
option in this case.
gblk config
Sometimes, you want to only keep a small number archives of your results
folder to save some space. If you always want to keep all backups from last week and one backup per month for 5 month, it can tedious to always remember the prune archive doing that:
gblk prune --keep-within '7d' --keep-monthly 5 --dry-run
You may want to put those settings in a local or in a global configuration file to always prune a given project or all your projects in the same way.
gblk provide a way to do that by using the borg configuration file .borg/config
as a local configuration file and the ~/.gblkconfig
file as a global configuration file.
If both the local and global configuration files contain gblk settings used for pruning, only the local settings are used.
Add new settings in configuration file
To add or update settings in the local configuration file you can use the following command:
gblk config add <KEY> <VALUE> [--global]
Where KEY
corresponds to a prune
command argument. You can choose from:
keep_within
,keep_last
,keep_minutely
,keep_hourly
,keep_daily
,keep_weekly
,keep_monthly
,keep_yearly
,prefix
,glob_archives
,save_space
AndVALUE
corresponds to the value to associate with the key
Check borg documentation to know what those arguments do. You can also run the command gblk prune --help
to see a description of those arguments.
You can also use the KEY
by replacing the ‘-’ by an ’_’. gblk will have the same behavior.
For example, to keep all backups from last week and one backup per month for 5 month, you must run the following command:
gblk config add keep-within '7d'
gblk config add keep-monthly 5
You can use the flag --global
to set those settings in the global configuration file
Display gblk settings used for pruning
To display the current list of setting of the gblk local or global configuration file, you can use the following command:
$ gblk config show # add --global to see setting the the global configuration file
keep_within = '7d'
keep_monthly = 5
The ‘-’ in keep_within is replaced by an underscore inside the configuration file
Remove gblk settings used for pruning
To remove a setting previouly defined in the local configuration file you can enter the following command
gblk config rm <KEY> [--global]
For example, let’s remove the setting keep_within
:
$ gblk config show
keep_within = '7d'
keep_monthly = 5
$ gblk config rm keep-within # 'gblk config rm keep_within' also works
$ gblk config show
keep_monthly = 5
To do the same thing with the global configuration file just add --global
at the end of those 3 commands.
Pruning archives using gblk settings
Finnaly, to prune your results archives using the settings defined in the global or local configuration you can use the following command:
gblk config prune [OPTION]
If both the local and global configuration files contain gblk settings used for pruning, only the local settings are used.
You can see what option you can add to your command with
$ gblk config prune --help
gblk-config-prune
Prune using the project configuration
USAGE:
gblk config prune [OPTIONS]
OPTIONS:
-h, --help Print help information
Filtering options:
-n, --dry-run Do not change the repository
--list Output verbose list of archive
-s, --stats Print statistics for the deleted archive
--force Force deletion of corrupted archives, use `--force --force` in case `--force`
does not work
gblk clone
, push
and pull
commands
Clone command
This command can be used after a git clone
command. If a gblk archive folder is available for the project, then you can execute the following command:
gblk clone [HOSTNAME:]PATH
Where PATH
is the path of a gblk archive folder. The PATH
must point to a folder containg tar files:
PATH
├── tar_file1
├── ...
└── tar_filen
Clone must be used with a path and not a remote name.
When cloning archives from a remote folder, gblk will ensure that all archive names correspond to exiting commits in your git project.
Here are the steps that the clone command execute:
- Checks if the current folder (or any parent folder) is a git repository
- Checks if the results folder exits
- Checks if the remote dir exits and contains tar file having commit names
- Initialize a .borg repository (
gblk init
) - Add a local remote called
origin
into the local config file - Pull every archive from that remote path
Here is the help of the clone commands:
gblk-clone
Clones a repository given a destination
USAGE:
gblk clone [OPTIONS] <PATH>
ARGS:
<PATH>
The path pointing to a borg folder
OPTIONS:
-c, --compression <COMPRESSION>
The compression to use automatically at each commit if hooks are created
[default: lz4]
-h, --help
Print help information
-H, --hooks
If specified, hooks are created inside `.git/hooks repository`
-m, --mode <MODE>
The checkout mode used by gblk automatically after a git checkout: soft or hard. This
option is only used if hooks are created. The hard mode will delete every file in your
results folder and extract those corresponding to the commit targeted by the checkout.
The soft mode will only update files that existed in the targeted checkout
[default: hard]
Push command
To copy the content of the .borg
folder into another location you can use the push
command like this:
gblk push KEY ARCHIVE
Where KEY
is the name of a global or local remote. Path are not supported!. And ARCHIVE
is an archive name defined in the .borg
repository or a branch/tag name of the git repository
Here are the steps that the push command execute:
- Checks if the current directory (or a parent directory) is a git repository, contain a results folder and a
.borg
repository - Checks if the remote folder (defined by the remote) exists
- Checks if the remote folder already contains the archive we want to push. If it exists, stop the process
- Creates a tar archives and copy it in the local or a remote filesystem. If the tar archive should be exported to a remote file system, then the tar file is created locally (in .tmp folder at the project root) and then exported remotely using rsync.
In the case a git branch name is used in this command, only the archive of the commit pointed by this branch/tag will be pulled
Pull command
The pull commands allow to replace the content of your .borg
archive into a remote folder.
It can be used with the following command:
gblk pull KEY ARCHIVES
Where KEY
is the name of a global or local remote. Path are not supported!. And ARCHIVE
is an archive name defined in the .borg
repository or a branch/tag name of the git repository
Here are the steps that the pull command execute:
- Checks if the current directory (or a parent directory) is a git repository, contain a results folder and a
.borg
repository - Checks if the remote folder (defined by the remote) exists and contains the archive to pull
- Check if the archive to pull is not already defined in our
.borg
folder. If it is, execute the next step - Import the archive in our
.borg
repository
You can you the --all
flag to pull all archives in the remote directory instead of one particular archives.
In the case a git branch name is used in this command, only the archive of the commit pointed by this branch/tag will be pulled
