首先说一下场景，我们在阿里云有几百台服务器包括linux 和window,现在要迁移服务器到百度云这边。
1.因为赶到马上过年，所以年前要将所有的sql数据文件备份一遍（现在想想，在不清楚迁移规则的情况下，最好先备份一个库然后将流程走通了，在一步一步的来，因为如果全部备份完成，会造成数据库日志无法收缩，导致日志增长数据很快，不得不购买磁盘扩大）
2.备份时要进行压缩备份
1.选择数据库-右键-任务-备份-常规 选择备份的地址，在备份选项里选择压缩备份 ，然后点击脚本 在新建窗口中进行 修改stats=1 按照1 递增，然后运行，在消息中就会看到执行的情况
2.如果备份了，日志增长太快，想恢复到以前的那种情况，现将数据库改成简单模式，然后收缩日志，完成后在改成完整模式（如果备份后，日志是不可以收缩的，因为要做日志追加操作，如果改动了日志追加就会出问题）
3.备份完成后 需要将阿里云的备份数据导入到百度云的服务器上，这里采用的是专线 具体的操作不是很熟悉，阿里云这边需要将服务器的vpcip 在百度云这边的专线路由里建立路由，阿里这边的云企业要建立百度云服务器的vpc 的路由，要规定到某个可用区，都要创建。然后从百度云同一个vpc下 ping 阿里云的某台服务器的内网ip 如果能ping通就证明可以沟通
4.网络沟通后 就可以进行内网数据迁移，我采用的是共享文件夹的方式进行copy, 将阿里云的sql备份文件夹进行共享，然后在百度云的网络 \\ip就能看到共享文件，然后进行copy就可以
5.copy完成后要进行sql备份还原操作，数据库-右键-还原数据库，还原选项要选择第二项，然后点击脚本 新建窗口运行 然后运行 最候结果数据库显示正在还原中就可以了（用脚本，这个好处就是大数据库，能看到进度）
4.进行sql日志备份，并且自动copy到百度云这边
1. 创建日志备份的存储过程
2.name in (\'数据库\') 备份一个，如果全部备份 ，not in(\'库1\',\'库2\')
3.需要备份哪个库要在日志备份的路径下建立相应的数据库名的文件夹
4.创建作业计划，每隔10分钟执行一遍（执行 （要加路径），exec [BackupDBLog] \'D:\DBBackup\log\\'）
5.有好多都是需要文件夹权限，如果报错，可以将文件夹权限修改一下

--exec [BackupDBLog] \'E:\sqlback\log\\'
set nocount on

--return
begin
declare @DateStr varchar(128)
declare @SqlStr varchar(4000)
declare @DBName varchar(128)
select @DateStr=replace(replace(replace(replace(convert(varchar(128),getdate(),25),\'-\',\'\'),\' \',\'\'),\':\',\'\'),\'.\',\'\')
select @DateStr
select @DateStr DateStr,name DBName,0 BackupStatus into #Temp

begin
select top 1 @DBName=dbname,@DateStr= DateStr from #Temp where BackupStatus=0
set @SqlStr=\'backup log \'+@DBName+\' to disk=\'+\'\'\'\'+@PathStr+@DBName+\'\\'+@DBName+@DateStr+\'.trn\'+\'\'\'\'+\' WITH COMPRESSION\'

--exec master..xp_cmdshell @sql
end
5.copy日志备份到百度云
1.xx 代表目标服务器的内网ip
2.如果报错开启一下xp_cmdshell(运行下面的语句就可以)
3.百度云也要创建对应的文件夹
4.如果操作一直失败，目标服务器的权限也有了，还是报权限问题 ，可以加上目标服务器的用户名和密码
5.创建计划任务每10分钟运行一次
declare @sql nvarchar(4000) set @sql=\'xcopy E:\DBBackup\DBName\log\*.trn* \\xx.xx.xx.xx\e$\log\DBName\ /y /D \' exec master.dbo.xp_cmdshell @sql
sp_configure \'show advanced options\', 1; GO RECONFIGURE; GO exec sp_configure \'xp_cmdshell\',1 go reconfigure with override go
declare @sql1 nvarchar(4000) declare @sql2 nvarchar(4000) set @sql1=\'net use \\xx.xx.xx.xx\D$ 密码 /user:用户名\' set @sql2=\'xcopy E:\sqlback\log\Aso_app_versions_log\*.trn* \\xx.xx.xx.xx\d$\sqlback\log\Aso_app_versions_log\ /y/D\' exec master.dbo.xp_cmdshell @sql1 exec master.dbo.xp_cmdshell @sql2
6.日志收缩
1.创建2个sql
2.完成后执行 dbo.sp_block \'r\' 查看进程
3.查看数据库的情况（第三段SQL语句）
4.收缩日志（第4段sql）
5. usedspace =第三段sql的已使用 ，totalspace=总共的
select @usedspace= 36043,@totalspace =38800
6.执行查看数据库是否收缩，如果收缩那说明成功了

REMARK:
1. 系统进程本身没有connection,一个sesstion对应一个connection
2. insert data有严格的顺序
3. 如果sys.dm_exec_requests的列值为null,表明此requests已经不存在,session_status为sleeping
4. if a spid is blocking and is blocked,it belong to blocked,but the blocking count has value.
5. if the sp get error info like "The statement terminated. The maximum recursion 100 has been exhausted before statement completion.",then it indicate a deadlock happened,like this: "Transaction (Process ID 67) was deadlocked on lock resources with anot
her process and has been chosen as the deadlock victim. Rerun the transaction.
6. sleeping: last_request_end_time>=last_request_start_time
7. 有时查询结果的数据出现不一致的情况,比如type=sleeping,而status=running,原因是此sp内部多次查询的时间差
8. 不论@status输入参数如何,blocking和blocked总是显示,可以用此特性只显示blocking和blocked
9. Will only display the blocking spid\'s query plan.
10. Will filter current spid,but if the current spid is blocking or blocked ,it will display.
11. 系统进程被阻塞,也会显示
12. session_status 有时不匹配 request_status,原因:存在脏读;或读取时间不一致
13. 不考虑自己阻塞自己的情况
