# Update a backup's comment
PATCH https://api.modulards.com/api/public/v1/site-backups/{siteBackup}
Content-Type: application/json
Writes the comment of one backup, replacing whatever it held: use it to record why the backup was taken. Send `null` or omit the field to clear it. The stored value is purified HTML: plain text comes back wrapped in a paragraph.
Your role must be allowed to update backups; without it the request answers 404.
**Body**
- `comment` (string or `null`, optional): at most 2500 bytes once HTML tags are stripped (a character outside plain ASCII counts as more than one byte).
**Errors**
- **422**: the comment is not a string or is too long.
Reference: https://api.docs.modulards.com/modular-ds-public-api/backups/website-backups/update-a-backup-s-comment
