hi, My testing database size is 800G and the LUN size is 1T. When I was running the jetstress 2010 backup test case, it produces the error "insufficient disk space (837553 MB needed, 186322 MB available". It seems it needs another 800G free space so that the test case can start. Anyone has met the same issue? How much free spaces is needed for backup test case? BTW, I didn't check "use disk for database backup test." If I select it, it needs more free space. Xiaodong_luo

The LUN size is 1T and database file size is 800G, so the free space is about 200G. I'm not sure how much free space is needed to run backup test? I didn't select the option "use disk for database backup test" According to the error message, it seems it needs free space equal to the dabase file size. is it true?Xiaodong_luo
