Run the following command to set the Informix environment: ./opt/informix/bin/setenv
Run onstat -d
Use the output generated from running this command to estimate how much database space is required for a CMS full maintenance backup. The data in this table is dynamic and changes as database space is used.
ADDITIONAL INFORMATION:
Note:
Bytes to GB conversion factor = 1,073,741,824.
Full Maintenance Backup compression ratio = 30 (approximation). The onstat -d command gives a current snapshot of disk space usage of the CMS server.
You must run additional checks periodically to see if your storage needs have changed to ensure that you have enough backup space.
