Public Preview: Introducing Vaulted Backup for Azure Data Lake Storage

Announcing the Public Preview of Vaulted Backup for Azure Data Lake Storage (ADLS)! Azure Backup now supports vaulted protection for ADLS, delivering secure, off-site backups that ensure business continuity and compliance—even in cases of accidental deletion, malicious activity, or ransomware. Vaulted backups maintain an independent copy of your data, isolated from the source account. Key Capabilities: * Off-site protection: Recover data even if the source account is compromised. Restore to original or alternate accounts. * Resilience against deletion and attacks: Isolated backups protect against insider threats and ransomware. * Automated & flexible scheduling: Configure daily/weekly schedules or trigger on-demand backups. * Long-term retention: Store backups for up to 10 years to meet compliance and archival needs. * Security-first design: Features like soft-delete, immutability, encryption, and multi-user authorization safeguard vault data. During public preview, you can configure vaulted backups for block blobs in HNS-enabled standard general-purpose v2 ADLS Gen2 accounts in the regions mentioned [here](https://aka.ms/AAvnn8l).
