Hi Karthik,

1. There are different levels of backup and you can, depending on your backup tool (onbar or ontape) you can either back up some dbspaces or all dbspaces.
2. Until you take a level 0 backup of the rootdbspace, if the instance needs to be restored, you will not only lose any data not backed up since the last backup, but you will also lose the definition of the new dbspace that you just created.
3. You should be taking regular backups anyway!
4. Given what I know of the size of your database, I would suggest taking an ontape backup of the entire database on a daily basis.
5. Since this is a test / development environment, you probably don't take regular backups, so whenever you see a message like this, take a full backup immediately.

Hope this helps!
