As per my understanding you can run a data export wizard and select only transactional record tables. I am not sure it allows you to flter these records before exporting. This will give you a dat file which can be kept as a backup. This dat file creation can be scheduled to run via a batch.
For the SQL DB these records meeting a criteria can be queried and deleted. I am not sure if this is what you are looking for, Thanks and Regards, Saurabh [Non-text portions of this message have been removed]
