About

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 tries to complete restic in order to offer a broader user experience.

Quickstart CLI

On Windows, use NPBackupInstaller.exe to install NPBackup into program files. On Linux, just copy npbackup to /usr/local/bin or use pip install npbackup

Copy the example config from model examples/npbackup.conf.dist into the directory where npbackup is installed.

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 is created automatically by the installer program. 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.

Quickstart GUI

Just run the npbackup executable and configure it.

Main minimalistic interface allows to:

• List current backups
• Launch a manual backup
• See if last backup is recent enough

Restore window allows to browse through backups and select what files to restore.

Configuration allows to edit the YAML configuration files directly as end user

Security Note 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 difficulty of laptop backups

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.

A good server backup solution

Server backups can be achieved by setting up a scheduled task / cron job.

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. When run on a server, prometheus support can be shifted from a push gateway to a file, which will be picked up by node_exporter file collector.:

Monitoring

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:

End user expericence

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.

Security

NPBackup inherits all security measures of restic (AES-256 client side encryption including metadata), append only mode REST server backend.

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 restore data without the need to know any password, without compromising a secret. Note that in order to use this function, one needs to use the compiled version of NPBackup, so AES-256 keys are never exposed. Internally, NPBackup never directly uses the AES-256 key, so even a memory dump won't be enough to get the key.

Compilation

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 Compile options are available in compile.py. Nevertheless, you should probably go for the official binaries. Also, We maintain a special 32 bit binary for Windows 7 which allows to backup those old machines until they get replaced.

Smart shield, antivirus and reputation

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.

Misc

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
