Agent Installation

Woodstock Backup architecture relies on a central server communicating with agents installed on client machines. This page explains how to install and configure agents on different platforms.

Overview

Woodstock Backup agents are responsible for:

• Analyzing local filesystems
• Executing backup operations
• Restoring files (if enabled)
• Secure communication with the central server

Download

When you add a new host in the Woodstock Backup interface, the system automatically generates an installation package containing:

• config.yml: The configuration file for the agent.
• Certificates needed for authentication.
• The agent executable for your operating system (for some platforms).

Windows Installation

After downloading, you will have a zip file containing:

• config.yml: The configuration file for the agent.
• ws_client_daemon.exe: The executable for Windows.
• Certificates needed for authentication.

Installation Steps

1. Extract the zip file contents to a folder of your choice. For example: C:\ProgramData\woodstock.
2. Open a Command Prompt with administrative privileges.
3. Navigate to the folder where you extracted the files:

cd C:\ProgramData\woodstock

4. Configure Windows Firewall to allow agent communications:

.\ws_client_daemon.exe --config-dir C:\ProgramData\woodstock install-fw-rule

5. Install the agent as a Windows service:

.\ws_client_daemon.exe --config-dir C:\ProgramData\woodstock install-service

The agent is now installed and running as a Windows service. It will automatically start with your computer and listen for instructions from the server.

Linux Installation (Generic)

After downloading, you will have a zip file containing:

• config.yml: The configuration file for the agent.
• ws_client_daemon: The executable for Linux.
• Certificates needed for authentication.

Installation Steps

1. Extract the zip file contents to a folder of your choice. For example: /opt/woodstock.
2. Open a terminal with administrative privileges.
3. Navigate to the folder where you extracted the files:

cd /opt/woodstock

4. Make the daemon executable:

chmod +x ws_client_daemon

5. Create a systemd service file. Open a text editor with administrative privileges and create a file at /etc/systemd/system/woodstock.service with the following content:

[Unit]
Description=Woodstock Backup Client
After=network.target

[Service]
ExecStart=/opt/woodstock/ws_client_daemon --config-dir /opt/woodstock
Restart=always
User=nobody
Group=nogroup

[Install]
WantedBy=multi-user.target

6. Reload the systemd daemon to recognize the new service and start it:

sudo systemctl daemon-reload
sudo systemctl enable woodstock.service
sudo systemctl start woodstock.service

The agent is now installed and running as a Linux service. It will automatically start with your computer and listen for instructions from the server.

Linux Installation (Debian/Ubuntu)

After downloading, you will have a zip file containing:

• config.yml: The configuration file for the agent.
• Certificates needed for authentication.

Installation Steps

1. Extract the zip file contents to the /etc/woodstock/ directory.
2. Open a terminal with administrative privileges.
3. Install the source package with the following commands:

sudo curl https://gogs.shadoware.org/api/packages/ShadowareOrg/debian/repository.key -o /etc/apt/keyrings/gitea-ShadowareOrg.asc
echo "deb [signed-by=/etc/apt/keyrings/gitea-ShadowareOrg.asc] https://gogs.shadoware.org/api/packages/ShadowareOrg/debian bookworm main" | sudo tee -a /etc/apt/sources.list.d/gitea-shadowareorg.list
sudo apt update

4. Install the agent package:

sudo apt install woodstock-client-rs

The agent is now installed and running as a Linux service. It will automatically start with your computer and listen for instructions from the server.

Configuration

The main configuration is done in the config.yml file. Here are all the available options:

Option	Description	Default Value
hostname	The name that identifies this host on the server	System hostname
bind	The network address to bind to	"0.0.0.0:3657"
password	Password for authentication with the server	-
secret	The secret key for the client	Randomly generated 64-byte hexadecimal string
backup_timeout	Timeout for backup operations in seconds	3600 (1 hour)
max_backup_seconds	Maximum duration of a backup operation in seconds	43200 (12 hours)
resolution_mode	Connection method to the server - "Direct" (default), "Mdns" (if compiled with mDNS support), or "None"	"Direct"
mdns_interfaces	Optional list of network interfaces to use for mDNS discovery	-
server	Server address when using Direct mode (required if resolution_mode is Direct)	-
disable_restauration	Set to true to disable restore capabilities for security reasons	false
xattr	Set to true to enable backup of extended attributes on Linux	false
acl	Set to true to enable backup of ACLs on Linux	false
auto_update	Enable automatic updates	true on Windows, false on other platforms
update_delay	Time in seconds between update checks	86400 (24 hours)
log_directory	Directory where logs will be stored	Same as the configuration directory

You can also start the agent with the --config-dir parameter to specify an alternative configuration directory, or set the CLIENT_PATH environment variable.

Command Line Options

The Woodstock Backup agent supports the following options:

Option	Description
--config-dir <path>	Specifies a custom configuration directory
--version	Displays the agent version

Subcommands (availability depends on platform):

Subcommand	Platform	Description
self-update	All	Updates the agent to the latest available version
install-service	Windows	Installs the agent as a Windows service
remove-service	Windows	Removes the Windows service
restart-service	Windows	Restarts the Windows service
run-service	Windows	Runs the program as a Windows service
install-fw-rule	Windows	Creates necessary Windows firewall rules
remove-fw-rule	Windows	Removes Windows firewall rules

Troubleshooting

Agent Unavailable

If the agent appears unavailable in the server interface:

1. Check that the service is running

   • Windows: Check Services Manager
   • Linux: systemctl status woodstock.service

2. Check log files in the configuration directory

3. Ensure certificates were properly installed

4. Verify that the firewall allows communications on necessary ports

   • TCP port 3657 (default)
   • UDP port 5353 (if mDNS is used)
