what have been done

1.remind users to archive the redundant data

2.provide special services for users:burn DVD for user to store data which never be used again.

3.remind users to backup the most important data to local hard disk

they are not enough to stop the data increasing

solution

FreeNAS（standby）

replace the old backup server with a desktop pc with a large disk space.Within 5 years, It will meet the uses request.

resources I need to solve it

1.one desktop PC2.several IP for test3.a little space in our datacenter 5th floor

Thank you
