The comparison was failing with "integer expression expected" error because AVAILABLE_SPACE contained whitespace characters. Changes: - Add tr -d '[:space:]' to clean AVAILABLE_SPACE value - Add validation for empty REQUIRED_SPACE (fallback to 1GB) - Add validation for empty AVAILABLE_SPACE (exit with error) - Add 2>/dev/null on comparison to prevent error messages - Improve error handling for edge cases Fixes: scripts/backup.sh: ligne 106 : [: 1712798932 0 : nombre entier attendu 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
