Fixes Windows, OpenBSD, and NetBSD builds by extracting
EstimateBackupSize from disk_check.go (which has build tags
excluding those platforms) to a new estimate.go file.
Why wrap external tools when you can BE the tool?
New physical backup engines:
• MySQL Clone Plugin - native 8.0.17+ physical backup
• Filesystem Snapshots - LVM/ZFS/Btrfs orchestration
• Binlog Streaming - continuous backup with seconds RPO
• Parallel Cloud Upload - stream directly to S3, skip local disk
Smart engine selection automatically picks the optimal strategy based on:
- MySQL version and edition
- Available filesystem features
- Database size
- Cloud connectivity
Zero external dependencies. Single binary. Enterprise capabilities.
Commercial backup vendors: we need to talk.
