Hi,
I really want to help but, are you saying you want a backup of the entire FILE or that you are looking to do Transactional History Change Tracking, where
you capture the rows data, before its changed based on the new data?
If so .... I would suggest
1) Adding a Status And Parent Column in Excel
Status is Active , Inactive
Parent is a Number, which represents the Excel Row Id, that you are essentially making inactive, while you insert the new row and make it active.
2) When triggered your flow should check if there is a row already. If so, set that row to Inactive, and create a whole new row, using all of the data
and set it to active.
now you will always have a historical change tracking
That or you can create another Sheet, call it Change Tracking History
Add a table
Make it the same as the existing Sheet/Table BUT add a Parent Column and an Archived DateTime Column, you wont need a history
When the flow triggers, find the latest instance of this record
Create a new row in the other sheet/table populating the Parent Column with the previous Row if it exists in the Archive and put the DateTime
just giving you options that work.
