我有一个表格（周期），并创建了一个触发器

alter trigger AnyName on Cycles
for insert,update,delete
AS
BACKUP DATABASE medrepcrm TO  DISK = N'C:\medrepcrm.bak' WITH NOFORMAT, INIT,  NAME = N'pcrm-Full Database Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10
GO

但是，当我在Cycle表中插入，更新或删除时，会导致错误。

Msg 3021, Level 16, State 0, Procedure AnyName, Line 8
Cannot perform a backup or restore operation within a transaction.
Msg 3013, Level 16, State 1, Procedure AnyName, Line 8
BACKUP DATABASE is terminating abnormally.
The statement has been terminated.

我该怎么做才能解决此错误？
