dbcc shrinkfile (sqcrm2009_log, 1);
go

 

#sql2005数据备份 "SaasCrm" 为数据库 "sql server代理 新建作业"

declare @strPath nvarchar(200)
set @strPath = replace(convert(nvarchar(19), getdate(), 120), ':', '.')
set @strPath = 'd:/CRM2_Bak/SaasCRM_' + @strPath +'.bak'
backup database [SaasCrm] to disk = @strPath with noinit,nounload,noskip,stats=10,noformat

 

 

可以将这个脚本放进crontab，他的配制文件在 /etc/crontab中每天凌晨执行一次，自动备份 这个脚本每天最多只执行一次，而且只保留最近五天的备份在服务器上。
