Hi @Sonal Patel,
Thanks for the question and using MS Q&A platform.
In Azure Database for PostgreSQL, point-in-time backups are mostly protected by security features that keep them safe from unauthorized access. However, these backups aren't completely immutable, meaning they can still be deleted or changed by users who have the right permissions.
While the platform has good security measures in place, it doesn't guarantee that backups can't be modified or deleted. If you need backups that are truly unchangeable, you might consider using Azure Blob Storage with WORM (write-once-read-many) policies.
