mssql 远程备份与还原

按照下面的方法恢复就可以了：

1、把你空间上的数据文件和日志文件全部备份。

2、当你的空间数据库出现问题的时候，删除原有数据库后，停止数据库服务。

3、把备份的数据库文件和日志文件覆盖到新建的数据库文件和日志文件上。

4、重启数据库服务，这样数据库就被恢复了。

以上，希望对你有所帮助。

手头上只有C#的代码，不知道对你有没有帮助

远程备份要注意权限的问题，普通的访问帐户没有备份和还原的权限，最好用sa的帐户，并且程序访问的帐户必须添加到远程机器的系统内

你说的远程备份到本地是不可能的，你只有开放远程某个文件夹加入你的特殊访问帐户权限

最好直接用远程桌面，这样最方便

方法一（不使用SQLDMO）：

///

///备份方法

///

SqlConnection conn = new SqlConnection("Server=.Database=masterUser ID=saPassword=sa")

SqlCommand cmdBK = new SqlCommand()

cmdBK.CommandType = CommandType.Text

cmdBK.Connection = conn

cmdBK.CommandText = @"backup database test to disk='C:\ba' with init"

try

{

conn.Open()

cmdBK.ExecuteNonQuery()

MessageBox.Show("Backup successed.")

}

catch(Exception ex)

{

MessageBox.Show(ex.Message)

}

finally

{

conn.Close()

conn.Dispose()

}

///

///还原方法

///

SqlConnection conn = new SqlConnection("Server=.Database=masterUser ID=saPassword=saTrusted_Connection=False")

conn.Open()

//KILL DataBase Process

SqlCommand cmd = new SqlCommand("SELECTspidFROMsysprocesses ,sysdatabases WHEREsysprocesses.dbid=sysdatabases.dbid AND sysdatabases.Name='test'", conn)

SqlDataReader dr

dr = cmd.ExecuteReader()

ArrayList list = new ArrayList()

while(dr.Read())

{

list.Add(dr.GetInt16(0))

}

dr.Close()

for(int i = 0i <list.Counti++)

{

cmd = new SqlCommand(string.Format("KILL {0}", list[i]), conn)

cmd.ExecuteNonQuery()

}

SqlCommand cmdRT = new SqlCommand()

cmdRT.CommandType = CommandType.Text

cmdRT.Connection = conn

cmdRT.CommandText = @"restore database test fromdisk='C:\ba'"

try

{

cmdRT.ExecuteNonQuery()

MessageBox.Show("Restore successed.")

}

catch(Exception ex)

{

MessageBox.Show(ex.Message)

}

finally

{

conn.Close()

}

方法二（使用SQLDMO）：

///

///备份方法

///

SQLDMO.Backup backup = new SQLDMO.BackupClass()

SQLDMO.SQLServer server = new SQLDMO.SQLServerClass()

//显示进度条

SQLDMO.BackupSink_PercentCompleteEventHandler progress = new SQLDMO.BackupSink_PercentCompleteEventHandler(Step)

backup.PercentComplete += progress

try

{

server.LoginSecure = false

server.Connect(".", "sa", "sa")

backup.Action = SQLDMO.SQLDMO_BACKUP_TYPE.SQLDMOBackup_Database

backup.Database = "test"

backup.Files = @"D:\test\myProg\backupTest"

backup.BackupSetName = "test"

backup.BackupSetDescription = "Backup the database of test"

backup.Initialize = true

backup.SQLBackup(server)

MessageBox.Show("Backup successed.")

}

catch(Exception ex)

{

MessageBox.Show(ex.Message)

}

finally

{

server.DisConnect()

}

this.pbDB.Value = 0

///

///还原方法

///

SQLDMO.Restore restore = new SQLDMO.RestoreClass()

SQLDMO.SQLServer server = new SQLDMO.SQLServerClass()

//显示进度条

SQLDMO.RestoreSink_PercentCompleteEventHandler progress = new SQLDMO.RestoreSink_PercentCompleteEventHandler(Step)

restore.PercentComplete += progress

//KILL DataBase Process

SqlConnection conn = new SqlConnection("Server=.Database=masterUser ID=saPassword=saTrusted_Connection=False")

conn.Open()

SqlCommand cmd = new SqlCommand("SELECTspid FROMsysprocesses ,sysdatabases WHEREsysprocesses.dbid=sysdatabases.dbid AND sysdatabases.Name='test'", conn)

SqlDataReader dr

dr = cmd.ExecuteReader()

ArrayList list = new ArrayList()

while(dr.Read())

{

list.Add(dr.GetInt16(0))

}

dr.Close()

for(int i = 0i <list.Counti++)

{

cmd = new SqlCommand(string.Format("KILL {0}", list[i]), conn)

cmd.ExecuteNonQuery()

}

conn.Close()

try

{

server.LoginSecure = false

server.Connect(".", "sa", "sa")

restore.Action = SQLDMO.SQLDMO_RESTORE_TYPE.SQLDMORestore_Database

restore.Database = "test"

restore.Files = @"D:\test\myProg\backupTest"

restore.FileNumber = 1

restore.ReplaceDatabase = true

restore.SQLRestore(server)

MessageBox.Show("Restore successed.")

}

catch(Exception ex)

{

MessageBox.Show(ex.Message)

}

finally

{

server.DisConnect()

}

this.pbDB.Value = 0
