FTPGrab

FTPGrab is a command-line application for automatically grabbing files from remote FTP or SFTP servers on a schedule. It is written in Go and distributed as a single binary or as a Docker image, making it practical to run on servers, desktops, and NAS devices.

Key Features

• Periodic downloads using an internal cron-style scheduler
• Supports multiple sources, with FTP and SFTP (SSH) connectivity
• Prevents re-downloads using hashing and an embedded key/value store to track previously downloaded files
• Include/exclude filtering using regular expressions and optional date-based filtering
• Retry support for failed downloads
• Ability to adjust downloaded file/folder permissions and ownership
• Modtime translation on downloaded files
• Notifications via email, Slack, webhooks, and other providers
• Enhanced logging for auditing and troubleshooting

Use Cases

• Pulling completed downloads from a seedbox to a home NAS on a schedule
• Periodic backup-like retrieval of files from remote FTP/SFTP servers
• Automated synchronization of specific folders with filtering and notifications

FTPGrab is a focused utility for scheduled file retrieval rather than a full bidirectional sync tool. Its single-binary and Docker delivery makes it straightforward to deploy across many platforms and architectures supported by Go.
