sub-folders—which can be especially
important for managing data protec-
tion in remote offices with limited
IT resources.
Disk usage analysis:
■ ■
The appliance
can use statistical information based
on previous backup performance to
predict disk space needs and help
ensure the necessary space is avail-
able to complete backup operations.
If additional space is needed, the
system can notify administrators in
advance and provide suggestions to
help remedy the situation without
affecting future backups.
Simplified alerting:
■ ■
Administrators no
longer need separate interfaces to eval-
uate component health—instead, a
single console provides integrated
alerting for backup destinations (see
Figure 2). The system can send alerts
when available disk space reaches each
of three thresholds administrators can
specify for a virtual disk. These alerts
help prevent jobs from failing because
of low disk space on a virtual disk.
comprehenSive protection
with Symantec backup exec
The Dell PowerVault DL2000 – Powered by
Symantec Backup Exec includes Symantec
Backup Exec 12.5 for Windows Servers, the
latest release of Symantec backup technol-
ogy. This software provides comprehensive
disk-to-disk-to-tape backup and recovery
for Microsoft Windows® OS–based physical
and virtual systems, including those running
Windows Server 2008. Patent-pending
Granular Recovery Technology (GRT) and
the continuous data protection provided by
Continuous Protection Server (CPS) can
deliver reliable point-in-time recovery for
critical Microsoft applications and enable
the rapid recovery of individual Microsoft
Exchange e-mails, Microsoft Office
SharePoint® Server 2007 documents, and
Microsoft Active Directory® user profiles.
agent for vmware virtual infrastructure
Data protection software has typically
treated virtualized environments as physical
environments, with agents often loaded
onto each virtual machine (VM) and
backups performed over the LAN.
Although this paradigm was sufficient for
a physical environment, it typically could
not meet backup and recovery objectives
for virtualized systems, often resulting in
performance degradation and missed
backup windows.
For environments based on VMware®
virtualization software, Backup Exec can
now utilize the Agent for VMware Virtual
Infrastructure, which supports data pro-
tection for an unlimited number of VMs
on an individual VMware ESX host. In
addition, Backup Exec is designed to use
numerous VMware technologies to
enhance backup and recovery in virtual-
ized environments. For example, it uses
VMware VirtualCenter to automate dis-
covery and presentation of VMware ESX
servers and VMs as part of the backup
environment. Administrators can also use
VMware Consolidated Backup (VCB) to
help minimize impact on VMs by taking
advantage of the VCB framework to per-
form off-host VM backups—VCB scripting
is no longer required, and an agent need
not be loaded into the virtualized environ-
ment to perform backups. Finally, GRT
enables the recovery of individual files and
folders from VCB image backups.
For environments based on Microsoft
virtualization software, Backup Exec can
now also utilize the Agent for Microsoft
Virtual Server, which supports data pro-
tection for an unlimited number of VMs
on an individual host server. In addition,
the agent supports both Microsoft
Virtual Server and Microsoft Hyper-V
™
technology. GRT enables the recovery
of individual files and folders from full
VM backups.
granular recovery technology
Critical applications can present their own
specific backup and recovery require-
ments. Recovery objectives, for example,
often dictate the ability to restore both a
full application and individual objects
within each application. As a result, orga-
nizations might choose from a variety of
methods for protecting applications—
methods that often consist of backing up
each application with a full database-level
backup and then performing a separate
backup of the individual items in these
databases. Because two or more backups
may be required to meet recovery objec-
tives, this approach can double the
amount of data and time required for
backup operations.
Backup Exec provides GRT for key
Microsoft applications, including Exchange,
