(*) Feature provided by restic backup backend
So, a new backup solution out of nowhere, packed with too much features for it's own good ? Not really !
NPBackup relies on the well known restic backup program, which has been battle proven for years.
While restic is a fanstastic program, NPBackup expands restic by offering a wider set of features.
Still, NPBackup repos are basically managed by restic, and can be viewed / restored / maintained by restic.
NPBackup consists of four programs:
- npbackup-cli: CLI version of the backup program
- npbackup-gui: GUI version of the backup program, useful to create YAML config files and for end users, can also act as cli
- npbackup-viewer: View and restore restic repositories without configuration
- upgrade_server: Separate server to provide npbackup clients with newer binaries
You may install npbackup via PyPI or use the pre-built executables.
On linux, uncompress the NPBackup tar.gz corresponding to your platform to /usr/local/bin, or wherever you want.
You'll get /usr/local/bin/npbackup-cli, /usr/local/bin/npbackup-gui or /usr/local/bin/npbackup-viewer depending on the flavor you have chosen.
You'll need to have write permissionds to /var/log. If not, you can specify an alternative log file via --log-file /my/writable/path/npbackup.log
Any distribution with glibc >= 2.17 should do.
On Windows, you should decompress zip archive and run the executable inside it. The x64 binary is compatible with Windows 10+. The x86 binary is compatible with windows Vista and higher. On those old systems, you might need to install Visual C runtime 2015.
If you don't want to use the pre-built executables, you can install via pip with pip install npbackup or pip install npbackup==3.0.0rc9 currently.
Python requirement: 3.7+
Note that if you want to use the GUI, you'll also need to install tkinter via yum install python-tkinter or apt install python3-tk.
Copy the example config from model examples/npbackup.conf.dist into the directory where npbackup is installed.
Also copy the excludes directory if you plan to use the prefilled bigger exclusion lists for your backups.
You can adjust the parameters directly in the file, or via a config GUI by launching npbackup --config-file=npbackup.conf --config-gui
Once configured, you can launch manual backups via npbackup --backup. Those can be scheduled.
Windows schedule can be created from the configuration page. On Linux, you'll have to create a cronjob or a systemd timer.
Since NPBackup is configured to only proceed with backups when no recent backups are detected, you should consider scheduling npbackup executions quite often. The default schedule should be somewhere around 15 minutes.
You can use npbackup --list or the GUI to list backups.
The GUI allows an end user to check current backups & restore files.rom backups:
The YAML configuration file encrypts sensible data so the end user doesn't have to know repository URI or password.
Just run the npbackup-gui executable and configure it.
Prebuilt binaries can be found here
Restore window allows to browse through backups and select what files to restore.
There is also a viewer mode that allows to browse all restic repositories without the need to configure anything, see below
Configuration allows to edit the YAML configuration files directly as end user
Orchestrator GUI allows to run commands on multiple repositories or groups.
Security
NPBackup' security model relies on symmetric encryption of all sensible data that allows to access a repository.
In order to achieve this, NPBackup contains an AES-KEY that can be set:
- at compile time
- at run time via an AES-KEY file
Please note that right clicking on "" in the configuration GUI will allow to decrypt that data, by prompting a backup admin password. That password is set at compile-time and should be different depending on the organization.
This allows a system admin to see repo URI and passwords, without leaving this information available on the computer.
The configuration file should never be world readable, as one could change the backup admin password, allowing to decrypt other parts of the conf file.
npbackup-viewer provides an easy to use GUI to view contents of various restic repositories, and restore files.
It accepts npbackup configuration files, restic style RESTIC_REPOSITORY and RESTIC_PASSWORD environment variables, and can virtually open and restore any restic repository.
Any optional S3/AWS/Google configuration can be set via the same environment variables restic uses.
If no configuration file nor environment variables are set, it will ask for repository and password settings.
As a matter of fact, laptop backups are the hardest. No one can predict when a laptop is on, and if it has access to internet. Creating a backup strategy in those cases isn't a simple task.
NPBackup solves this by checking every 15 minutes if a backup newer than 24h exists. If so, nothing is done. In the case no recent backup exists, a backup is immediately launched. OF course, both time options are configurable. In order to avoid sluggish user experience while backing up, process and io priority can be lowered. Once done, NPBackup can send backup results in Prometheus format directly to a push gateway, for prometheus to catch them.
Server backups can be achieved by setting up a scheduled task / cron job manually or via integrated task creation.
Of course, since NPBackup supports pre-exec and post-exec commands, it can be used to backup various services like virtual hosts or databases where snapshot/dump operations are required (especially with new stdin_from_command parameter).
NPBackup includes full prometheus support, including grafana dashboard. On servers, we'll configure a prometheus file that gets written on each backup, and later can be collected by node_exporter.
On laptops, since we might be away from our usual network, we'll push the backup metrics to a remote push gateway which laters gets collected by prometheus itself.
The current NPBackup dashboard:
While admin user experience is important, NPBackup also offers a GUI for end user experience, allowing to list all backup contents, navigate and restore files, without the need of an admin. The end user can also check if they have a recent backup completed, and launch backups manually if needed.
npbackup-cli has all the functions the GUI has, and can run on any headless server.
It also has a --json parameter which guarantees parseable output.
You may run operations on multiple repositories, or repositories groups by specifying paramater --repo-group or --repo-name.
--repo-name allows to specify one or multiple comma separated repo names, also allows special __all__ argument which selects all repositories.
--repo-group allows to specify one or multiple comme separated repo group names, also allows special __all__ argument which selects all groups.
Multi-repo example:
npbackup-cli --housekeeping --repo-group default_group
npbackup-gui can also act as cli if run with --run-as-cli parameter, allowing to use a single executable as GUI and scheduled tasks.
NPBackup inherits all security measures of it's backup backend (currently restic with AES-256 client side encryption including metadata) and all security options from it's storage backends.
On top of those, NPBackup itself encrypts sensible information like the repo uri and password, as well as the metrics http username and password.
This ensures that end users can backup/restore data without the need to know any password, avoiding secret compromission.
Note that NPBackup uses an AES-256 key itself, in order to encrypt sensible data. The public (git) version of NPBackup uses the default encryption key that comes with the official NPBackup repo.
You can generate a new AES-256 key with npbackup-cli --create-key npbackup.key and use it via an environment variable:
Use a file
export NPBACKUP_KEY_LOCATION=/path/to/npbackup.key
Use a command that provides the key as it's output
export NPBACKUP_KEY_COMMAND=my_key_command
You may also compile your own NPBackup executables that directly contain the AES-256 key. See instructions in PRIVATE directory to setup keys.
By default, npbackup is allowed to execute all operations on a repo.
There are some situations where an administrator needs to restrict repo operations for end users.
In that case, you can set permissions via the GUI or directly in the configuration file.
Permissions are:
- full: Set by default, allows all including destructive operations
- restore: Allows everything backup does plus restore, check and dump operations
- backup: Allows, backup and snapshot/object listing operations
On Unix, logs will be found in /var/log unless the directory is not writable. In that case, we'll write into a temporary directory.
On Windows, logs will be found in the current directory, or in temp directory defined in %TEMP% variable or %WINDIR%\TEMP when current directory isn't writable.
You can also use --log-file to specify an alternative log file path.
NPBackup comes with integrated auto upgrade function that will run regardless of program failures, in order to lessen the maintenance burden.
The upgrade server runs a python asgi web server with integrated HTTP basic authentication, that can further be put behind an SSL proxy like HaProxy.
NPBackup is fully customizable and branding can be done easily.
You'll find all images and icons in the resources directory. Feel free to update those files. Once updated, you must run update_custom_resources.py to regenerate the customization.py file corresponding entries.
The file customization.py also contains OEM strings that can be safely changed, except for the license text which must stay unaltered.
In order to fully protect the AES key that is needed to support NPBackup, one can compile the program with Nuitka.
Compiling needs restic binary for the target platform in RESTIC_SOURCE_FILES folder, files must be named restic_{version}_{platform}_{arch}[.extension] like provided by restic.net or github
Linux binaries need to be made executable in the RESTIC_SOURCE_FILES folder.
You can use update_restic.sh script in RESTIC_SOURCE_FILES to download binaries.
You'll need to change the default AES key in secrets.py, see the documentation in the file itself.
One you're setup, you need to install compilation tools, see requirements-compilation.txt file.
Compile options are available in compile.py.
We maintain a special 32 bit binary for Windows 7 which allows to backup those old machines until they get replaced.
We also compile our linux target on RHEL 7 in order to be compatible with reasonably old distributions (>= glibc 2.17).
arm and arm64 builds are compiled on Debian stretch for use with glibc > 2.24.
On most Linux distributions, you might get your glibc version by running find /usr -name "libc.so.6" -exec "{}" \;
Official binaries for Windows provided by NetInvent are signed with a certificate, allowing to gain trust and reputation in antivirus analysis.
Also, official binaries are compiled using Nuitka Commercial grade, which is more secure in storing secrets.
Pre-compiled builds for Windows have been code signed with NetInvent's EV certificate, using windows_tools.signtool
Signing on a Windows machine with Windows SDK installed can be done via windows\sign_windows.py script.
Alternatively, you can sign executables via:
from windows_tools.signtool import SignTool
signer = SignTool()
signer.sign(r"c:\path\to\executable", bitness=64)
Or as singleliner to use in scripts:
python.exe -c "from windows_tools.signtool import SignTool; s=SignTool(); s.sign(r'C:\GIT\npbackup\BUILDS\public\windows\x64\npbackup-viewer-x64.exe')"
NPBackup supports internationalization and automatically detects system's locale. Still, locale can be overrided via an environment variable, eg on Linux:
export NPBACKUP_LOCALE=en
On Windows:
set NPBACKUP_LOCALE=en
