[ask-bonk]

All checks pass. Here is a summary of the documentation changes made based on cloudflare/sandbox-sdk#437:

Changes

src/content/docs/sandbox/api/backups.mdx (API reference)

1. Parameters section (createBackup()): Added exclude and excludeDefaults parameter descriptions
2. Throws section: Updated InvalidBackupConfigError description to cover validation of exclude (non-string values, control characters) and excludeDefaults (non-boolean)
3. BackupOptions type definition: Added exclude?: string[] and excludeDefaults?: boolean fields
4. BackupOptions fields table: Added documentation for both new fields, including the default exclude list and merge behavior

src/content/docs/sandbox/guides/backup-restore.mdx (how-to guide)

1. New "Exclude files from backups" section with three subsections:
   • Use default excludes — example using excludeDefaults: true
   • Specify custom exclude patterns — example using the exclude array
   • Combine defaults with custom patterns — example using both together
2. Best practices: Added a new bullet recommending excludeDefaults / exclude to reduce archive size

Closes #28760
