DPM 2016 UR4
This article describes improvements and issues that are fixed in Update Rollup 4 for Microsoft System Center 2016 Data Protection Manager. This article also contains the installation instructions for this update. See more information about this update.
Note Existing Data Protection Manager to Windows Azure customers should upgrade to the latest agent (version 2.0.9085.0 or a later version). If the latest agent is not installed, online backups may fail.
Backup storage migration
With this update installed, you can now migrate your backup storage between volumes. This enables you to optimize storage usage, as you can choose to move and store data sources on volumes that are best suited to optimize performance. You can also migrate data sources when a volume is filled with backups and can't be extended.
DPM 2016 with Modern Backup Storage accepts volumes to store backups, and formats the selected volumes to ReFS. While DPM excludes system volumes in the list of volumes that are available to be formatted, additional volumes can be configured to be excluded from the list based on drive letter or mountpoint path. This avoids accidental selection of these volumes as backup volumes.
Support for TLS 1.2
TLS 1.2 is a secure method of communication that is recommended by Microsoft. For DPM, TLS 1.2 is applicable for certificate-based authentication and protecting workloads to cloud.
For more information about how to set up, configure, and run your environment with TLS 1.2, see the following article in the Microsoft Knowledge Base:
4051111 TLS 1.2 Protocol Support Deployment Guide for System Center 2016
Custom size allocation
When you create a Protection Group to back up files and folders, size calculation can take a long time if the folders contain many files. You can changing a registry key to instruct DPM to accept the volume size as default instead of calculating the size of each file, thereby saving time.
Optimized CC for RCT VMs
Optimized consistency check for Hyper-V RCT based VM backup eliminates the storage bloat caused by CC operation of RCT VM and also improves the performance of this operation.
Improvements and issues that are fixed
BMR and System State data source backups consume more storage when you use Modern Backup Storage.
When you configure Tape Library sharing, SetSharedDpmDatabase.exe command crashes when SQL 2012 is used as the DPM database.
If a disk backup is in progress, tape backup jobs of the data source may fail.
Alternate synchronization jobs for files and folders on a deduped volume raise failed files alerts incorrectly. Failed files log links in failed files alerts doesn't show the failed files.
If many data sources are protected by the primary DPM server, enabling protection from the secondary DPM server may fail and return error 36.
When you try to recover files and folders from Azure, some items in the online recovery point are not visible in the user interface when the item has a path length longer than 256 characters.
Console crashes occure while enabling protection of a file share that is protected by a primary DPM server from a secondary DPM server.
The user interface stops responding for several minutes when triggering a Consistency check job.
Severity of the alert that is raised when an online backup fails due to new disk backups present since the last online backup is lowered from “Critical” to “Informational.”
