sqlserver 数据库备份及恢复

手动备份当然是用 sqlserver manage studio,不记了

 

程序备份 先连接数据库：

 string connstring = "server=" + 服务器 + ";User ID=" + <a href="/tag/yonghuming/" target="_blank" class="keywords">用户名</a> + ";Password=" + <a href="/tag/mimap/" target="_blank" class="keywords">密码</a> + ";database=master;"; <a href="/tag/sql/" target="_blank" class="keywords">sql</a>Connection con= new <a href="/tag/sql/" target="_blank" class="keywords">sql</a>Connection(_ConnString); con.<a href="/tag/open/" target="_blank" class="keywords">open()</a>;

备份代码：

string <a href="/tag/sql/" target="_blank" class="keywords">sql</a>Bk = "Backup DATABASE " + <a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>名 + " TO <a href="/tag/dis/" target="_blank" class="keywords">dis</a>K='" + 保存<a href="/tag/wenjian/" target="_blank" class="keywords">文件</a>名(全路径的,空格好像有问题) + "'"; <a href="/tag/sql/" target="_blank" class="keywords">sql</a>Command <a href="/tag/sql/" target="_blank" class="keywords">sql</a>CMD = null; <a href="/tag/sql/" target="_blank" class="keywords">sql</a>CMD = new <a href="/tag/sql/" target="_blank" class="keywords">sql</a>Command(<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Bk,con); Int32 r = 0; try { <a href="/tag/sql/" target="_blank" class="keywords">sql</a>CMD.CommandTimeout = 0; //一直等待到结束 r = <a href="/tag/sql/" target="_blank" class="keywords">sql</a>CMD.ExecuteNonQuery(); Message<a href="/tag/Box/" target="_blank" class="keywords">Box</a>.Show("<a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>备份完毕！","",Message<a href="/tag/Box/" target="_blank" class="keywords">Box</a>Buttons.OK,Message<a href="/tag/Box/" target="_blank" class="keywords">Box</a>Icon.@R_954_<a href="/tag/404/" target="_blank" class="keywords">404</a>5@ion); saveP(); } catch (Exception ex) { Message<a href="/tag/Box/" target="_blank" class="keywords">Box</a>.Show(ex.Message,Message<a href="/tag/Box/" target="_blank" class="keywords">Box</a>Icon.Error); } finally { con.Close(); }

恢复代码：

string <a href="/tag/sql/" target="_blank" class="keywords">sql</a>Restore = @"ALTER DATABASE '" + <a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>名 + "' SET OFFLINE WITH ROOLBACK IMMEDIATE;" //先将<a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>离线比较保险，不然可能不能恢复 +"RESTORE DATABASE " + <a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>名 + " FROM <a href="/tag/dis/" target="_blank" class="keywords">dis</a>K = '" + 备份<a href="/tag/wenjian/" target="_blank" class="keywords">文件</a> + "' WITH MOVE '" + <a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>名 + "' TO '" + 新库<a href="/tag/wenjian/" target="_blank" class="keywords">文件</a>路径 + @"/" + <a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>名 + ".mdf',MOVE '" + <a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>名 + "_log' TO '" + 新库<a href="/tag/wenjian/" target="_blank" class="keywords">文件</a>路径 + @"/" + <a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>名 + "_log.ldf',STATS = 10,REPLACE;" +"ALTER DATABASE '" + <a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>名 + "' SET ONLINE WITH ROOLBACK IMMEDIATE;"; //恢复完成使<a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>在线 <a href="/tag/sql/" target="_blank" class="keywords">sql</a>Command <a href="/tag/sql/" target="_blank" class="keywords">sql</a>CMD = null; <a href="/tag/sql/" target="_blank" class="keywords">sql</a>CMD = new <a href="/tag/sql/" target="_blank" class="keywords">sql</a>Command(<a href="/tag/sql/" target="_blank" class="keywords">sql</a>Restore,con); Int32 r = 0; try { <a href="/tag/sql/" target="_blank" class="keywords">sql</a>CMD.CommandTimeout = 0; //一直等待到结束 r = <a href="/tag/sql/" target="_blank" class="keywords">sql</a>CMD.ExecuteNonQuery(); Message<a href="/tag/Box/" target="_blank" class="keywords">Box</a>.Show("<a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>恢复完毕！",Message<a href="/tag/Box/" target="_blank" class="keywords">Box</a>Icon.@R_954_<a href="/tag/404/" target="_blank" class="keywords">404</a>5@ion); saveP(); } catch (Exception ex) { Message<a href="/tag/Box/" target="_blank" class="keywords">Box</a>.Show(ex.Message,Message<a href="/tag/Box/" target="_blank" class="keywords">Box</a>Icon.Error); } finally { con.Close(); }
