 **Microsoft Azure Backup Server version 4 (MABS V4) Update Rollup 1** includes critical bug fixes and feature enhancements. To view the list of bugs fixed and the installation instructions for MABS V4 UR1, see [KB article 5032421](https://support.microsoft.com/help/5032421/).
 
+>[!Important]
+>We're temporarily pausing the release of Update Rollup 1 for Microsoft Azure Backup Server V4 due to the known issue - **Hyper-V scheduled backups take a long time to complete because each backup job triggers a consistency check.**
+>
+>Error message: The replica of Microsoft Hyper-V RCT on `<Machine Name>` is not consistent with the protected data source. DPM has detected changes in file locations or volume configurations of protected objects since the data source was configured for protection. (ID 30135).
+>
+>Resolution: This will be resolved in the new version planned to be released soon.
+>
+>- If you haven't installed UR1 for MABS V4 already, wait for the new release.
+>- If you have already installed UR1 for MABS V4, this new build will install on top of UR1 for MABS V4 to fix the known issues.
+>
+>For additional information, reach out to Microsoft Support.
