can you say how much you mean by "many logs" and how many days you went ?

a database will generate some logs even with a small or no email traffic so basically nothing to worry about

It was for about 10-12 days and i had thousands of logs

What do you mean by DB will create small amount of traffic even with no email ?

By design. CCR closes and ships logs to keep the replication healthy.

Well I guess MegaNuk3 gave you the clarification for my reply above.

Even with low or no traffic exchange keeps the logs going (one every 90 seconds if my memory is correct) to minimize the data loss risk.

Let's say one log was opened and then was not filled in hours because the mail traffic was very low in that case a crash will lead to hours of data loss. for that reason Exchange will close and replicate the log every 90 sec to keep the data loss to minimal
