Renz	a0e7fd71de	security: Implement HIGH priority security improvements ... HIGH Priority Security Features: - Path sanitization with filepath.Clean() for all user paths - Path traversal attack prevention in backup/restore operations - Secure config file permissions (0600 instead of 0644) - SHA-256 checksum generation for all backup archives - Checksum verification during restore operations - Comprehensive audit logging for compliance New Security Module (internal/security/): - paths.go: ValidateBackupPath() and ValidateArchivePath() - checksum.go: ChecksumFile(), VerifyChecksum(), LoadAndVerifyChecksum() - audit.go: AuditLogger with structured event tracking Integration Points: - Backup engine: Path validation, checksum generation - Restore engine: Path validation, checksum verification - All backup/restore operations: Audit logging - Configuration saves: Audit logging Security Enhancements: - .dbbackup.conf now created with 0600 permissions (owner-only) - All archive files get .sha256 checksum files - Restore warns if checksum verification fails but continues - Audit events logged for all administrative operations - User tracking via $USER/$USERNAME environment variables Compliance Features: - Audit trail for backups, restores, config changes - Structured logging with timestamps, users, actions, results - Event details include paths, sizes, durations, errors Testing: - All code compiles successfully - Cross-platform build verified - Ready for integration testing	2025-11-25 12:03:21 +00:00
Renz	e80c16bf0e	Add reliability improvements and config persistence feature ... - 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)	2025-11-19 04:43:22 +00:00
