a way to archive data from a database table?

Hi all,

i read data from a database table into an internal table for some evaluation. Each time after the evaluation I had a line to the table. There is a counter ( i.e a row type i) and when it has a certain value I need to empty the database table and start counting from 1. I would like to archive the data in another table after emptying the original table every time. Is it a good way to do this? Which table type should I use to archive. The data will increase each time. It is about 10000 data to save every time i empty the table.

Thanks for your help.
