## What it is
BackupPC is a high-performance, enterprise-grade backup system that backs up Linux, Windows, and macOS machines to a server's disk. It uses file pooling and compression to minimize storage, requires no client-side software, and provides a web-based CGI interface for administration.

## Use cases
- back up multiple laptops and desktops to a central server disk
- deduplicate identical files across many machine backups to save storage
- back up Windows PCs over SMB without installing client software
- back up Linux servers via rsync or tar over ssh
- give users a web interface to browse and restore their own backups
- reduce 1200GB of raw backup data down to 150GB with pooling and compression

## When to choose
- you need centralized disk-based backups for a heterogeneous fleet of Linux, Windows, and macOS machines
- you want strong deduplication to dramatically cut storage costs
- you prefer a mature, self-hosted solution with no client-side agents
- you need a web UI for both admins and end users to manage restores

## When to avoid
- you need backup to tape or cloud object storage as the primary target
- you want a modern stack - BackupPC is written in Perl with a CGI interface
- you need block-level or bare-metal disaster recovery backups
- you prefer actively modern alternatives like Borg, Restic, or Duplicati
