Avunu server tools addons

Scheduled Odoo database backups to any FS Storage (S3 and other fsspec protocols), with credentials read from environment variables. It is an Odoo 18.0 module built and maintained by Avunu LLC for our own client work and published for anyone to use. The repository extends OCA/server-tools: the module adds a backup method to its auto_backup.

Modules

Each module's README explains why it exists and how it works.

Branches

develop is the default branch and the one pull requests go to. Its code targets Odoo 18.0, the series named in .odoo-series. 18.0 follows develop automatically (a workflow fast-forwards it after every push) and is the branch to install or pin. When a newer Odoo series is maintained, it gets its own branch (19.0, …) and changes flow up to it from develop.

Install

Requires Odoo 18.0 and a PostgreSQL database. Installing a module pulls in the modules it depends on (see below), and those must be on your addons_path first.

With a plain Odoo checkout, clone this repository on its 18.0 branch and add it to the addons path:

git clone --branch 18.0 https://github.com/Avunu/server-tools-addons.git
odoo-bin --addons-path=odoo/addons,/path/to/server-tools-addons,<your other addons paths> \
  -d <database> -i auto_backup_fs_storage --stop-after-init

With odoo-nix, add the repository from the dev shell. odoo module add accepts an owner/repo and a branch, adds it as a submodule, and the addons path is regenerated from the folders present (run direnv reload afterwards):

odoo module add Avunu/server-tools-addons 18.0

OCA dependencies can be added by module name, which also adds the OCA repositories that hold them: odoo module add auto_backup fs_storage.

Dependencies

Each module's __manifest__.py is the source of truth. auto_backup_fs_storage lists no Odoo core module directly; it depends on the following. The OCA repositories listed are the 18.0 branches; clone both, along with whatever their modules need in turn (their own manifests list it).

Those two declare Python packages of their own: paramiko, pysftp and cryptography for auto_backup, and fsspec for fs_storage. The odoo_backup storage this module creates on install uses S3, which needs fsspec's S3 support (fsspec[s3], as the fs_storage README lists).

Development

The repository carries its own development environment, built by odoo-nix in addons mode. OCB and the repositories these modules depend on are flake inputs pinned in flake.lock, and the Python environment is locked in nix/. You need Nix with flakes, and optionally direnv.

git clone https://github.com/Avunu/server-tools-addons.git && cd server-tools-addons
direnv allow                  # or: nix develop --no-pure-eval
devenv up                     # PostgreSQL, Odoo and Mailpit
odoo db provision             # a database with every module here installed
odoo test auto_backup_fs_storage

After nix flake update, or when a module gains a depends or a Python requirement, run odoo project relock and commit flake.lock and nix/. A new dependency on another repository also needs its input and an externalSources entry in flake.nix. See odoo-nix's A repository of addons.

Tests

Odoo runs a module's tests when you install or update it with --test-enable. Select a module's tests with a --test-tags filter and use a throwaway database:

odoo-bin -c odoo.conf -d <testdb> -i auto_backup_fs_storage \
  --test-enable --test-tags /auto_backup_fs_storage --stop-after-init

auto_backup_fs_storage has automated tests; its README runs them with this same command.

Licence

Every module is licensed under the GNU Affero General Public License v3.0 or later, as its __manifest__.py also states (AGPL-3, Odoo's identifier for version 3).

Provenance

auto_backup_fs_storage moved here, with its history, from Avunu/avunu-odoo-addons in November 2026, when Avunu split that repository into one repository per OCA area.
