🔧 Advanced Topics

⚙️ Configuration

AeonSync can be configured using command-line options or by modifying the configuration file:

hostname = "myworkstation"
remote_address = "[email protected]"
remote_path = "/volume1/backups"
remote_port = 22
retention_period = 30
source_dirs = ["/home/user/projects", "/var/www", "/etc"]
exclusions = [".cache", "*/node_modules", "*.tmp", ".venv"]
ssh_key = "/home/user/.ssh/id_rsa"
verbose = False
log_file = "/home/user/.local/share/aeonsync/aeonsync.log"
default_daily_backup = False  # Set to True to allow only one backup per day

📁 Remote Structure

AeonSync organizes your backups as follows:

/volume1/backups/
└── myworkstation/
    ├── latest -> 2024-03-15
    ├── 2024-03-15/
    ├── 2024-03-14/
    ├── 2024-03-13.1/
    ├── 2024-03-13/
    └── ...

• Each backup is stored in a date-stamped directory
• Multiple backups per day append a sequence number (e.g., 2024-03-13.1)
• The latest symlink always points to the most recent backup
