Solution

You can using copy task as ussualy like image below:

and then we can config source and sink. and then in that sink you can add dynamic on that file name like image below:

on dynamic content you can add script:

@concat(‘<filename>_’,formatDateTime(addhours(utcnow(),7),’yyyyMMddHHmmss’),’.txt’)

I’m using addhours +7 for the Indonesia time than UTC time.

Conclusion

in Azure Data Factory we can backup data with copy task to another folder/container with dynamic content.
