Veeam Backup 6 Patch3

Patch3 (KB1442) for Veeam Backup & Recovery v6 was released this week with a lot of bug fix and enhancements. As usual, all patches are cumulative. So you can install Patch3 on a fresh Veeam install.

Here are the fixes from this patch :

• Application-aware processing fails for SQL server where Veeam configuration database is located.
• Cannot specify 0 in re-IP rule.
• Hot add operation can sometimes cause a very long backup source/target proxy Virtual Machine stun. This stun can be so long that it can cause all jobs using this backup proxy to fail due to timeout with:_Error: Client error: A connection attempt failed because the connected party did not properly respond after a period of time_.
• CBT may fail on  virtual disks other than Hard Disk 1 with the _Soap fault. A specified parameter was not correct_ error when the hot add processing mode is used.
• Backup console UI freezes periodically (upon automatic refresh event) when there is a large number of managed objects exist.
• Any job processing the same Virtual Machine longer than 48 hours is forcibly terminated.The new timeout is set to 7 days.
• Very large jobs start failing with the _Failed to save file content_ error after the VBM metadata file reaches 4 MB in size.
• Hyper-V CSV ownership change during backup or replication preparation process may take too long with certain storage devices, causing bug check (BSOD) on Hyper-V hosts.
• Hyper-V virtual disks with the disk file’s extension in capital letters (.VHD) are backed up like regular files, and not like virtual disks.
• Copying very large files to Linux or ESX host with service console credentials specified may fail.

And enhancements :

• For VMware virtual machines with multiple disks, hot add was changed to only happen once for each processed virtual machine instead of multiple times, before each processed disk.
• Improved VMware replication failback performance by enhancing the virtual disk digest calculation process.
• Improved vPower NFS performance by removing some excessive logging.
• Changed the warning about outdated VMware Tools on the processed virtual machine to an information event.
• Removed CBT warning from the initial run of backup and replication jobs which have backup and replica mapping configured.
• Added support for adding Hyper-V with Veeam Backup and Replicationg installed. Previously, adding the host would fail with the User credentials cannot be used for local connections error.
• Improved bottleneck analysis formulas for proxy and network processing stages. For example, heavy backup target load should no longer affect the Network stage percent busy value.
