I have the following questions regarding the on-tape utility: 1. I am using Informix 7.22 on SCO Unix 5.0.5. How can I check how much space the ontape backup occupies on the tape? 2. Currently I have a database with 6 dbspaces. The total capacity of those is about 36 GB. The ontape backup fits on one tape (DLTtape IV). If I increase the number of dbspaces and also the capacity to 150 GB will the ontape backup fit on one tape? What I mean is that does the ontape utility backup the total space allocated to dbspaces either free of occupied by data) or only the data? Thanks, Vasilis

If it will not fit on one tape, ontape will ask for second. >What I mean is that > does the ontape utility backup the total space allocated to dbspaces >either free of occupied by data) > or only the data?
