When you create an index, Adaptive Server writes the create index transaction and the page allocations to the transaction log, but does not log the actual changes to the data and index pages. To recover a database that you have not dumped since you created the index, the entire create index process is executed again while loading transaction log dumps.
If you perform routine index re-creations (for example, to maintain the fillfactor in the index), you may want to schedule these operations to run shortly before a routine database dump.
