The restore operation cannot be done from the OS itself. You'll need to raise a support ticket with Microsoft operations. The restore operation requires the HANA Large Instance (HLI) to be in powered off state, so schedule accordingly.

Managed OS snapshots

Azure can automatically take OS backups for your HLI resources. These backups are taken once daily, and Azure keeps up to the latest three such backups. These backups are enabled by default for all customers in the following regions:

• Batı ABD
• Doğu Avustralya
• Güneydoğu Avustralya
• Orta Güney ABD
• Doğu ABD 2

This facility is partially available in the following regions:

• Doğu ABD
• Kuzey Avrupa
• Batı Avrupa

The frequency or retention period of the backups taken by this facility can't be altered. If a different OS backup strategy is needed for your HLI resources, you may opt out of this facility by raising a support ticket with Microsoft operations. Then configure Microsoft Snapshot Tools for SAP HANA to take OS backups by using the instructions provided earlier in the section, Take a manual backup.
