Backing up the Domain Index and Catalog
Back up the Domain Index and the Domain Catalog as often as necessary to be useful to your organization. Weekly backups are probably sufficient for most organizations.
About this task
Make sure you back up the entire FTDOMAIN.DI subdirectory on the indexing server as soon as the server has completed building the index for the first time.
Important: Before you
back up the Domain Index, check the Domain Indexer Status view in
the Domain Catalog to make sure that the Domain Indexer task has finished.
If you attempt to back up the Domain Index while the Domain Indexer
task is running, catastrophic data loss can result.
You can include the Domain Catalog (CATALOG.NSF) in the databases for transaction logging. However, do not back up the Catalog while the Catalog task is running.
