3.0 Issues Fixed

This update fixes the following issues, which could have occurred:

• A problem where not all Microsoft Exchange emails are displayed when expanding a recovery point after generating a GRT catalog from a CA ARCserve D2D backup of Microsoft Exchange 2003 or Microsoft Exchange 2007. After you apply this fix, run a new backup with GRT enabled. (Test Fix T2D2978)
• A problem that causes a CA ARCserve D2D backup to fail with error code 64 and the following message: "Can't find file: error=64,trying to find .VHD file CDescFile::AddMetaDataSection: WriteFile failed. err[6]". (Test Fix T5LE123)
• A problem that causes a backup to a NAS device to fail with a WriteDisk error in the Backup log and the following error message in AFStor.log “FATAL ERROR! There are 512 bytes of data left unwritten”. (Test Fix T5LE122)
• A problem that always causes CA ARCserve Central Host-Based VM Backup to perform a full backup even though an incremental backup was specified. The following entries are logged in to the backup log: "Disk XXX size changed, DiskSize=167040034816, NewDiskSize=167040035328" and "Do full backup for disk XXX because it is newly added or its size changed." (Test Fix T2D2954)
• A problem that causes a backup job to fail at the end of the job while trying to collect disaster recovery information. The following message is displayed in the backup-*.log file: "[AFBackupEntryLocalD2D]: [Shrink CHK] [Collect DR information] Volume size has been changed, current session will be deleted and next backup will be converted to verify." (Test Fix T36A800)
• A problem that causes a CA ARCserve D2D Backup Exchange node job to crash if it is time to purge the transaction log. (Test Fix T2D2964)
• A problem that causes an incorrect backup type in the backup xml file. All CA ARCserve D2D backups show as incremental backups even though a full backup does exist. This problem is caused by an incorrect backup type in BackupInfo.xml under the full backup session, which prevents full backups to display on the CA ARCserve D2D home page. After you apply this fix, run a new merge job to correct the BackupInfo.xml file. (Test Fix T2D2966)
• A problem in Cloud Configuration for a copy job, that causes the "Test Connection" to fail if the proxy server uses the Basic method for authentication. The following error message is recorded in Azure.log: "CAAzureUtils.processStorageException - StatusCode:407 Error Code: ServiceBadResponse Error Message:Proxy Authentication Required Access Denied" (Test Fix T245831)
• A problem where some virtual machines that perform backup from CA ARCserve Central Host-Based VM Backup receive the following warning message: "Could not get volume information from virtual machine guest OS". The result of this is that the catalog is not created for the VM, and therefore file level restores are not possible. (Test Fix T2D2971)
• A problem that prevents a bare metal recovery for a Microsoft Windows Server 2012 server with UEFI from automatically generating a default volume (recovery partition) in Advanced mode. (Test Fix T5TM103)
• A problem that causes a merge to fail with error 31 when recovery points reside on certain NAS devices. (Test Fix T5E5198)
• Data Corruption tool: The data corruption detection utility (AFUtil.exe) performs a full scan of your recovery points to confirm the integrity of the backed-up data. For more information about this problem and the use of the data corruption detection utility, see the Recovery Point Merge Failure May Render Recovery Point Unrecoverable topic in the CA ARCserve D2D online help. (Test Fix RO57870)
• A problem when you create a policy in [assign the value for egcm in your book] and you set the File Copy settings to the Amazon S3 cloud destination, the bucket name on the cloud does not contain a prefix after the policy is assigned to each CA ARCserve D2D machine. This issue can cause two different CA ARCserve D2D machines copying the data to the same bucket. After you apply this fix, create a policy and deploy it to all CA ARCserve D2D machines. (Test Fix T2D2961/RO58326)
• A problem where a file copy catalog synchronization job from the Cloud takes a long time to complete. This fix uses multithreading to synchronize the catalog which improves the performance. The default thread number is 8 and the maximum value is 10. You can change the thread number by creating a DWORD value ThreadForCatalogSync under:

  HKEY_LOCAL_MACHINE\SOFTWARE\CA\CA ARCserve D2D\AFArchiveDll

  For more information, see Configure File Copy Settings to Optimize Performance. (Test Fix T2D2982)

• A problem that causes files under the D2D\BIN folder to be deleted unexpectedly if the check license task fails in a copy recovery point job. (Test Fix T5E5203)

For all issues fixed in this release, see the CA ARCserve D2D r16.5 Release Notes.

4.0 Known Issues

The following issues could exist in this update:

• If the backup destination is a deduplicated-enabled NTFS volume on Windows Server 2012, and CA ARCserve D2D is installed on Windows 2003 or Windows XP, restore, merge, or catalog jobs can fail. The job fails with Windows error code 50 and message "The request is not supported".

  Symptom:

  McAfee or another third party software set EnableECP=1 in the registry when they are installed on Windows Server 2012.

  Solution:

  In the registry, change the value of EnableECP from 1 to 0 under the following key:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanManServer\Parameters

  For more information, see http://support.microsoft.com/kb/2817216.

• Unable to boot the server after performing a BMR.

  Symptom:

  When the source machine is an Active Directory server performing a BMR to a physical machine with different hardware or to a virtual machine on a hyper-v server, the server does not boot and a blue screen displays with the following message:

  STOP: c00002e2 Directory Services could not start because of the following error: a device attached to the system is not functioning. Error status: 0xc0000001.

  Solution:

  Reboot the system to the BMR PE environment, rename all *.log files in the C:\Windows\NTDS folder, and restart the system. For example, rename the file edb.log to edb.log.old and restart the system.

For all known issues in this release, see the CA ARCserve D2D r16.5 Release Notes.

5.0 Limitations

The following limitations could exist in this update:

• CA ARCserve D2D requires the file attribute "system" to convert the backup destination folder to the ARCserve D2D View. However, on some NAS filers, the file attribute "system" is not supported, therefore you cannot change the destination to the ARCserve D2D View.

For all limitations in this release, see the CA ARCserve D2D r16.5 Release Notes.
