 | Parallel online backup jobs - limit enhancement | MABS V4 supports increasing the maximum parallel online backup jobs from *eight* to a configurable limit based on your hardware and network limitations through a registry key for faster online backups. [Learn more](backup-azure-microsoft-azure-backup.md). |

-## What's new in MABS V3 UR2 Hotfix?
-
-This update contains the following enhancement to improve the backup time. For more information on the enhancements and the installation, see the [KB article](https://help.microsoft.com/support/5031799).
-
-**Removed File Catalog dependency for online backup of file/folder workloads**: This update removes the dependency of MABS 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. This Hotfix allows MABS V3 UR2 to use a modern *iSCSI mount* method to provide individual file restoration.
-
-**Advantages**:
-
-- Reduces the backup time by up to *15%* because file catalog metadata (list of files in a recovery point) isn't generated during the backup operation.
-- - Item-level recovery errors due to inconsistent file catalog metadata are avoided because *iSCSI mounts* are used.
-- - After the recovery point is mounted, file browsing during item-level recovery is faster for recovery points with many files and folders.
-
->[!Note]
->We recommend that you update your MABS V3 installation to Hotfix for Update Rollup 2 to benefit from the enhancement. Ensure that you also update your MARS Agent to the latest version (2.0.9262.0 or higher).
