(REG_DWORD) registry values in minutes. The new, increased defaults are 30 and 45 minutes respectively.Hyper-V
• Under certain scenarios of dynamic VHD virtual disk size increase, changed block tracking information can be reset, resulting in incremental job run having to read the entire VHD to determine the incremental changes.
• Performing compact operation on VHD virtual disk can reset changed block tracking information.
• Instant VM Recovery fails with the "Connection with Hyper-V mount agent was lost
" error for VMs with dynamic VHD disk size not being a multiple of 256MB.

" error, depending on how destination folder was selected in the replication job wizard.
• Veeam jobs may cause non-VM owner Hyper-V nodes to log the following events to the system event log: "(eventid = 8194): "Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied
• Changed block tracking functionality does not function on cluster disks.Application-aware processing
• Exchange 2003 running in VM restored from Veeam backup may rename its mailbox databases after each subsequent reboot.Backup Copy
• Retry cycles cause incorrect processing duration shown in the Backup Copy job report.
• Backup Copy job reports show the inflated traffic savings ratios due to being calculated off the incorrect parameter.
• Certain Backup Copy jobs failures result in Backup Copy job report not send immediately, but rather at the end of the copy interval.
• A number of additional enhancements to the Backup Copy job report.File level recovery
• Copy To fails on files with long paths with the following error: "The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248
• Mount cache files should now be cleaned up from %AppData%
folder automatically.Guest indexing
• Guest file system catalog data processing performance was accelerated a few times in cases when the catalog contains very large amount of restore points.
• Catalog service may take a very long time to start when there is a large data upload queue present.1-Click VM Restore
• File restore operator scope settings should no longer affect ability to perform VM restore in certain scenarios with overlapping permissions.Built-in WAN Acceleration

• Drive to library matching code does not process some symbols in the serial numbers, resulting in matching problems with certain tape libraries (for example, QUADStor VTL).
• Added ability to disable tape device rescan completely with the DisableTapeSubsystem
(REG_DWORD) registry key. This can help in situations when the same tape devices is shared between multiple backup solutions.
• In some cases, stopping tape jobs can cause backup session not finalized correctly, resulting in future attempts to write to the same tape failing with the "Tape positioning" error.

This newer R2 build additionally addresses the following issues introduced with the original R2 build (126.96.36.1994):
• Backup and replication jobs fail with the "Dynamic library cannot be loaded" error when the backup proxy is missing C++ redistributable components (such as in case of clean OS install). Alternatively to installing this newer build, you may instead choose to install C++ redistributable components from http://vee.am/runtime
• "Transferred" job counter displays the same value with "Read" counter in cases when both source and target data movers are running on the same server (such as when backup proxy is writing data to its own disk). This is purely a cosmetic issue, as the actual transferred amount is lower due to source-side dedupe and compression.
• Tape backup jobs writing to a standalone tape drive hangs on processing the second task in the job.Known IssuesGeneral
• Network traffic verification does not function when the Use multiple upload streams per job option is disabled.vSphere 5.5
• E1000E vNIC adapters have been found to crash ESXi host under heavy load. Avoid using them until the patch is available from VMware. For more information, please refer to VMware KB2059053
• Virtual appliance (hot add) processing mode does not support SATA disks. This is by design of VMware hot add functionality, which requires SCSI adaptors.
• vSAN beta is not supported. Hyper-V 2012 R2
• Offhost backup from deduplicated volume fails if Data Deduplication feature is disabled on backup proxy server, or incompatible with Windows Server deduplication version used on backed up volume.
• Shared VHDX virtual disks backup is not supported.Windows Server 2012 R2
• In Windows Server 2012 R2 environments with Windows Server deduplication feature in use, be sure to install Veeam Backup & Replication on Windows Server 2012 R2, and enable Data Deduplication feature. Windows Server 2012 deduplication driver is not compatible with Windows Server 2012 R2 deduplication, causing file level recovery errors with false data corruption reports.R2a update is superseded by Patch #3 (above)
