How to deal with completed/cancelled projects in Primavera?

Hi All,

Our Primavera database is getting bigger and bigger those day with the completed/cancelled projects, I am thinking of start set up some process to backup and removed the Projects no longer required from the system.

I had thinking the backup strategy and following is what I thought:

(1) Perform a full database backup on production and then delete those completed/cancelled projects from Production system. It can be done on annual basis, but I can imagine we will end up in lots of copy of Primavera databases after couple years time.

(2) In P6 Client, perform an export on completed/cancelled Projects as XER file and saved them into a file system. But the issue will be the baseline projects, as I known, at present, P6 Client still not support export Projects with baseline. Which is means I will need to restore every baselines and export them separately, consider that is thousands of projects, it is a labor intensive task.
