What is the safest backup option?

• A. Backing up only the attachments is the safest option.
• B. Backing up the whole home directory is the safest option.
• C. Backing up the confluence.cfg.xml is the safest option.
• D. Backing up only the logs is the safest option.

Answer: (B)

In disaster recovery, you want a backup that captures both data and how the system is configured. The Confluence Home directory stores attachments, user avatars, the search index, caches, installed plugins, and the main configuration file. Backing up the entire Home directory ensures you have all of these components in one restore, so you can bring Confluence back online with its data, settings, and structure intact.

Backing up only attachments would miss configuration and other essential data; backing up only logs would miss the attachments and configuration; backing up only the configuration file would miss attachments and other crucial pieces. So the safest option is to back up the whole Home directory.
