Backup solution for DDEV preview servers

[titouanmathis]

Problem

A DDEV preview server hosts dozens of projects with databases and uploaded files. If the server dies, source code is recoverable from Git, but databases and uploaded files are not.

Proposed Solution

Agent-level scheduled backup using ddev export-db per project, with optional remote push (S3, rsync).

Features

• trafic backup CLI command for manual runs
• Scheduled task in the agent (tasks/backup.ts)
• trafic restore CLI command
• Configurable retention and remote storage

Config Example

[backup]
enabled = true
schedule = "0 3 * * *"
retain_days = 7
local_dir = "/var/backups/trafic"

[backup.remote]
type = "s3"
bucket = "my-trafic-backups"

CLI Surface

trafic backup                    # Backup all projects
trafic backup --name my-app      # Backup specific project
trafic backup --list             # List available backups
trafic restore --name my-app --date 2026-02-07
