o Makes the VM snapshot available to the third-party software.
o The backup software performs an ordinary backup of the VM snapshot moving the data to a backup medium.
o The backup software calls the post-backup script:
o Unmounts 220 701 the VM snapshot from the backup proxy.
o Takes the VM out of snapshot mode.
o Types of VCB backups:
o Image-level backup
o File-level backup
o Full file backup
o Differential backup
o Incremental backup
o VCB proxy:
o Windows 2003 SP1 (32-bit or 64-bit)
o Windows 2003 R2 (32-bit or 64-bit)
o Windows 2003 SP2 (32-bit or 64-bit)
o Windows 2008 – Server Core (command line) not supported.
o Disable automatic drive-letter assignment to newly seen volumes:
o diskpart
o automount disable
o Clean out entries of previously mounted volumes: automount scrub
o VCB configuration file: C:\Program Files\VMware\VMware Consolidated Backup Framework\config\config.js
o You need to specify a user name.
o Use the same password you use for logging in to the vCenter host or ESX Server host.
o If you do not specify the password, VCB checks if the password is set in the registry.
o You can configure VCB to use Security Support Provider Interface (SSPI) for authentication.
o When VCB communicates with the vCenter server or ESX Server host, it can transfer data over an encrypted SSL connection or use an
unencrypted network channel.
o VCB supports a maximum of 60 concurrently mounted VMs disks.
o In the Hot-Add mode, you need to create a shadow VM for VCB to use internally. The shadow VM has the same name as your virtual VCB
proxy with the (VCB-HELPER) suffix added.
o If you are using VCB 220 702 in the Hot-Add mode, in addition to the VCB User role, you need to create the VMware VCB Proxy role.
o You cannot perform a file-level backup simultaneously with an image-level backup for the same VM.
o When you perform a first backup for a VM, the VM has to be powered on, otherwise the backup fails.
o You do not need to power on a VM if your integration module is configured to use VM display names instead of IP addresses or DNS names.
o VMware VSS Component. Guest operating systems:
o Windows Server 2003 32-bit/64-bit
o Windows Vista 32-bit/64-bit
o Windows Server 2008 32-bit/64-bit
o VCB uses the VMware VSS component to create quiesced snapshots of the VM volumes.
o 2003 – VSS snapshots are application-consistent.
o Vista & Windows Server 2008, the snapshots are file-system consistent.
o SYNC Driver
o XP 32-bit
o 2000 Server 32-bit
o 2003 32-bit
o SYNC driver holds incoming I/O & flushes all dirty data to a disk, making snapshots file-system consistent.
o Locations of Custom Quiescing Scripts:
o Pre-freeze – C:\Program Files\VMware\VMware Tools\backupScripts.d or /usr/sbin/pre-freeze-script – All scripts are invoked in ascending
alphabetical order with freeze as the first argument.
o Post-thaw – C:\Program Files\VMware\VMware Tools\backupScripts.d or /usr/sbin/post-thaw-script – All scripts are invoked in
descending alphabetical order with thaw or freezeFail as the first argument.
o Cleaning Up After a Failed Backup Job: run vcbCleanup at the end of your backup cycle.
Appendix A: Using Service Console to Back Up & Restore VMs (valid for ESX4?)
o /etc/vmware/backuptools.conf configuration file to set the most common parameters
o You can use vcbMounter to back up an entire VM in the service console. The vcbMounter utility creates a quiesced snapshot of the VM &
exports the snapshot 220 701 into a set of files, which can be later used to restore the VM.
o To search for a particular VM & get information about it, use vcbVmName.
o You can back up a VM to a local directory or to a remote server using scp.
o Use vcbSnapAll to create an archive of groups of VMs in the service console. The vcbSnapAll utility has the same functionality as vcbMounter,
