# MySQL 8.0.24 备份恢复自动化测试脚本
|

# ============================================================================
|

# 作者: AI Assistant
|
||||
# 版本: 1.0.0
|
||||
# 说明: 自动化测试备份和恢复功能
|
||||
#
|
||||
# 测试流程:
|
||||
# 1. 创建测试数据库和测试数据
|
||||
# 2. 执行全量备份
|
||||
# 3. 添加增量数据
|
||||
# 4. 执行增量备份
|
||||
# 5. 删除测试数据库
|
||||
# 6. 从全量备份恢复
|
||||
# 7. 应用增量备份
|
||||
# 8. 验证数据完整性
|
||||
# 9. 清理测试数据
|
||||
#
|
||||
# 使用方法:
|
||||
# ./test_backup_restore.sh [选项]
|
||||
#
|
||||
# 选项:
|
||||
# --skip-cleanup 测试后不清理数据
|
||||
# --verbose 显示详细输出
|
||||
# -h, --help 显示帮助信息
|
||||
#
|
||||
# 注意:
|
||||
# - 测试会创建临时数据库 'backup_test_db'
|
||||
# - 请确保 MySQL 用户有创建/删除数据库的权限
|
||||
# - 测试完成后会自动清理 (除非指定 --skip-cleanup)
