For this reason, the conversion may fail if the amount of unoptimized data is greater than the capacity of the destination volume. 177 How Backup Exec determines if a file has been backed up. virtual machine snapshot, right-click does not delete option-Veritas Backup Exec error. When a job is submitted for backup with the AOFO selected, a snapshot of each volume. Veritas Backup EXEC 21 Settings Backup Tasks, Programmer Sought.
On PCs as well as Windows Servers you can also use VSSADMIN: vssadmin list shadows. The Symantec Backup Exec Advanced Open File Option (AOFO) uses advanced open file and image technologies designed to alleviate issues that are sometimes encountered during backup operations, such as protecting open files and managing shortened backup windows. As a preventative measure you’ll also want to set the VSS storage area size limit to ‘unbounded’. Backup the key and delete Symantec one, reboot and see if at least Windows Server Backup will back to work If Symantec Exec still works improperly after deleting the key (but WSB does), test to remove and reinstall Symantec Exec to see the result. In other words, an unoptimized data transfer is performed. You’ll want to delete all scheduled shadows and delete all existing shadows on each drive. The converted disk data is not deduplicated. If the physical computer runs Windows Server 2012 or later with one or more Windows deduplication volumes, conversion to a Hyper-V host is possible, but it may fail. For example, if the physical computer runs Windows Server 2012 with an ReFS volume, conversion to a Windows Server 2012 Hyper-V host is supported.
Storage Spaces and Storage Pools are not supported.Ĭonversion to any previous versions of a Windows Hyper-V host is not supported, so those jobs fail. The conversion of physical computers that have dynamic disks is not supported. The conversion of physical computers that have simple GPT disks is supported. The physical computer's disk sector size is maintained during the conversion. also a reboot of the backup server does this. Go to Storage and check under datamanagement Allow Backup Exec to delete all expired backup sets.
The vhdx files can have a maximum capacity of 64 TB. Verify your account to enable IT peers to see that you are a professional. When the AOFO agent kicks in, it works with the VSS providers in the operating system to create snapshots. Option 3: Fix the VSS issue thats causing it in the first place During the installation of Windows 2008 R2 RTM, it creates a Recovery Partition thats about 100MB.
Incremental and differential backups update the virtual machine that was created from the full backup.īefore you create a job to convert a physical computer to a Windows Server 2012 and later Hyper-V host, review the following information:ĭisk data is stored in vhdx files for conversion of a physical computer to a virtual machine running on a Windows Server 2012 and later Hyper-V host. Option 2: Wait until Backup Exec 2010 comes out with official support for R2. These options require a smaller backup window than the simultaneous conversion options.Ī conversion from a full backup creates the new virtual machine. These options let you schedule the conversion to run after the backup job. See Converting to a virtual machine simultaneously with a backup job.īack Up to Disk and then Convert to Virtual Machineīack Up to Deduplication Disk Storage and then Convert to Virtual Machine In the case of a failed conversion, the conversion process runs again during the next full backup. For a conversion failure, the job is marked as a success with exceptions. However, if the conversion fails, the backup continues to run. Therefore, if the backup fails, then the conversion fails also.
To see which providers are installed, launch Windows Services on the guest machine and confirm one of services from the table above are listed.Incremental backups are preferred over differential backups because the differential backups are inefficient for conversion as compared to incremental backups.Īlthough the backup runs simultaneously with the conversion, the backup is the primary job. Once the Backup Exec Remote Agent is installed, thus installing the BE VSS Provider, do NOT re-install the VMware Tools VSS Provider as this will re-create the conflict condition and cause quiesce and/or snapshot errors. The Backup Exec VSS Provider cannot exist in a guest alongside the VMware Snapshot Provider as having both installed on a guest will cause quiesced snapshots to hang the guest and timeout. "When installing the Backup Exec Remote Agent on a guest machine for GRT enabled virtual machine backups, the VMware Snapshot provider is automatically uninstalled and the BE VSS Provider installed (this is why a reboot is required).
