我使用这个脚本从我的 sql server 数据库中获取备份
DECLARE @name VARCHAR(50) -- database name
DECLARE @path VARCHAR(256) -- path for backup files
DECLARE @fileName VARCHAR(256) -- filename for backup
DECLARE @fileDate VARCHAR(20) -- used for file name
--Path to backups
SET @path = 'E:\DataBase Backups\'
SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)
DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
WHERE name NOT IN ('master','model','msdb','tempdb','ReportServer','ReportServerTempDB')
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @name
WHILE @@FETCH_STATUS = 0
BEGIN
--Remove if you dont want a date stamp
SET @fileName = @path + @name + '_' + @fileDate + '.BAK'
-- SET @fileName = @path + @name + '.BAK'
BACKUP DATABASE @name TO DISK = @fileName with noinit
FETCH NEXT FROM db_cursor INTO @name
END
CLOSE db_cursor
DEALLOCATE db_cursor
此代码每天制作新的备份文件,但我需要用今天的备份替换我的旧备份,或者在制作今天的备份后,所有旧备份都被删除了!请你帮助我好吗?
