Hotfix for Update Rollup 2 for Microsoft Azure Backup Server v3

Introduction

This article describes the improvements contained in Hotfix for Update Rollup 2 for Microsoft Azure Backup Server V3. This article also contains the installation instructions for this update.

Issues that are fixed

This update rollup hotfix removes the dependency of Microsoft Azure Backup Server V3 on File Catalog (list of files in a recovery point, maintained in the cloud), which was needed to restore individual files and folders from the online recovery points. With Hotfix for Update Rollup 2, MABS V3 will use a modern iSCSI mount method to provide individual file restores.

The new method has the following advantages:

1. Reduces backup time by up to 15% since file catalog metadata (list of files in a recovery point) is not generated during backup.

2. Item level recovery errors due to inconsistent file catalog metadata is avoided since iSCSI mounts are used.

3. After the recovery point is mounted, file browsing during item level recovery is faster for recovery points with many files and folders.

It is highly recommended that you update your MABS V3 installation to Hotfix for Update Rollup 2 to benefit from the enhancement. 

Important: Once you update to MABS V3 UR2 Hotfix, ensure that you also update your MARS version to be 2.0.9262.0 or higher.

In addition to the above enhancement, all the issues fixed in MABS V3 UR2 are also included in MABS V3 UR2 Hotfix.
