- Implement context cleanup with sync.Once and io.Closer interface - Add regex-based error classification for robust error handling - Create ProcessManager with thread-safe process tracking - Add disk space caching with 30s TTL for performance - Implement metrics collection with structured logging - Add config persistence (.dbbackup.conf) for directory-local settings - Auto-save/auto-load configuration with --no-config and --no-save-config flags - Successfully tested with 42GB d7030 database (35K large objects, 36min backup) - All cross-platform builds working (9/10 platforms)
