# Rebuild Day Backup ### Rebuild day Backup The Rebuild day backup option recreates the (Current day backup) directory from the program backup directory. The REBUILD directory has all information the Back-Office needs to rebuild the day. This option is used only if the contents of the REBUILD directory are corrupted. The backup directory is a copy of data from the last End of Day. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
