Checkpoint Template File Description
The checkpoint template file drives the checkpoint and roll forward operations. If needed, you can tailor the file to meet the requirements of your site.
For example, if the database exists on multiple locations, checkpointing backs up each location to a separate tape or disk and, in turn, roll forward restores each location one at a time. If you want to use a different backup method or only one tape for all locations, you can edit this command file.
