2.0 New Features for BrightStor ARCserve Backup r11.5

These sections provide an overview of the new features added to BrightStor ARCserve Backup, to help you identify and utilize the powerful new functionality of BrightStor ARCserve Backup. This release of BrightStor ARCserve Backup for Windows provides support for:


2.1 Smart Restore

Smart Restore is an automated process that BrightStor ARCserve Backup deploys to ensure that restore jobs continue without interruption, even when a media error occurs. Media or tape drive errors or hardware problems can cause a restore job to fail. If this occurs, BrightStor ARCserve Backup immediately scans your environment to find duplicate copies of the backup session that was being restored. This functionality is available when back up is performed using the Disk Staging Option or tapecopy. If a duplicate, or clone, of the backup session exists, BrightStor ARCserve Backup uses the copied session to complete the restore job automatically.


2.2 Optimize Restore Option

BrightStor ARCserve Backup discovers duplicate backup sessions, where one session resides on tape media and another session resides on a file system device, the Optimize Restore option directs BrightStor ARCserve Backup to restore the data from the session that resides on the file system device. This functionality is available when back up is performed using the Disk Staging Option or tapecopy.

Under most circumstances, restoring data from a file system device is faster than restoring from tape media. However, you may wish to consider disabling the Optimize Restore option if you are using tape media or a library with high-speed reading capabilities.

The Optimize Restore option is a global setting that is applied to all restore operations, and is enabled by default. To disable the Optimize Restore option, clear the check mark from the Optimize Restore check box.


2.3 Disk Staging Option

Using the Disk Staging Option you can back up data to a temporary data storage location, migrate (copy) the data to permanent storage media, and purge the data from the staging area at a later time. When necessary, the Disk Staging Option lets you restore data directly from the staging device.

Backing up to a file system device is generally faster than backing up to tape media. Faster backups require smaller backup windows. In addition, you can further decrease the backup window by streaming jobs simultaneously to a file system device.

BrightStor ARCserve Backup provides you with the capability of streaming multiple jobs simultaneously to the FSD. The base product allows you to write a maximum of two streams per job simultaneously. Licensing the Disk Staging Option enables you to increase the simultaneous streams to 32 (for each job and each staging group).

The Disk Staging Option also reduces the restore window. Restoring data from disk is generally faster than restoring from a tape, because there are no delays due to tape load and seek latency. When you back up data to a staging device, you can create policies so that the data can remain on the staging device after it is copied to tape media. If you need to restore data that exists in two locations (on the device and on tape), you can reduce the restore window by restoring your data directly from the staging device rather than retrieving the data from a tape stored in an off-site vault.

The Disk Staging Option provides you with the flexibility to change your backup destination by defining staging policies. For example, if your tape library is disabled, you can divert the backup job to an alternate file system device or library. Similarly, if a file system device reaches its storage threshold or is disabled, you can divert the backup job to a tape library.

Note: You cannot change the backup destination once the job has been created.

In addition, staging provides you with the following features:


File System Device Capacity Management

Using the Disk Staging Option you can specify file system device capacity thresholds. The threshold can be represented as either the total volume used or as a percentage of the disk's total capacity used. This feature affords the following benefits:


Multistreaming

The Disk Staging Option lets you back up multiple jobs to the same file system device simultaneously, decreasing the backup window. Multistreaming provides you with the ability to restore data while backup jobs are running.

The BrightStor ARCserve Backup base product allows you to stream two jobs simultaneously. To stream more than two jobs, you must license the Disk Staging Option. After you license the Disk Staging Option, you can transmit up to 32 streams of data to the staging device.


SnapLock Support

SnapLock™ is technology from Network Appliance that provides non-erasable, non-rewritable, Write Once Read Many (WORM) data security. SnapLock is available on any Network Attached Storage (NAS) device from Network Appliance that supports at a minimum ONTAP™ version 6.4.1.

When you back up data using SnapLock protection, you cannot purge or over-write the backed up data until the specified retention date elapses. This ability helps to ensure that your enterprise complies with regulatory data-retention requirements.


Command Line Support

BrightStor ARCserve Backup lets you create backup to staging device jobs using either the graphical user interface or the command line utility. In the event a copy to tape operation fails, you can use the Query tool to analyze the file and session contents on the staging device. You can purge sessions from a staging device, using the Purge tool to remove data and free disk space from a staging device.


2.4 Microsoft SharePoint Portal Server Support

BrightStor ARCserve Backup Windows Agent for Microsoft SharePoint works with BrightStor ARCserve Backup to efficiently back up and restore Microsoft SharePoint Portal Server 2003 and Microsoft Windows SharePoint Services data. The agent helps BrightStor ARCserve Backup retrieve and send data to and from the servers in your network in a consistent manner.

The Agent for Microsoft SharePoint offers a number of features to facilitate your backup and restore operations:


2.5 One Button Disaster Recovery (OBDR) Support for Window XP and Windows 2003

The Disaster Recovery Option now supports One Button Disaster Recovery (OBDR) on Windows XP and Windows 2003. In traditional Disaster Recovery, a bootable CD and a floppy are needed to recover a system. With BrightStor ARCserve Backup OBDR support and OBDR capable hardware, you can recover a system using a single tape drive. OBDR uses Windows Automated Systems Recovery (ASR) technology.

OBDR also provides an enhanced user interface, improved error logging and faster recovery speed.


Disaster Recovery Integration with Disk Staging Option

Disaster Recovery integrates with Disk Staging Option. If you migrate or purge backup data an update of your disaster recovery information is triggered automatically to keep your machine-specific recovery information up to date.


Disaster Recovery for StorageTek ACSLS

Disaster Recovery supports local recovery of Windows 2003 backup servers using StorageTek ACSLS tape libraries.


Disaster Recovery for Windows Small Business Server 2003

Disaster Recovery for Windows Small Business Server 2003 allows you to backup and restore the default configurations of Windows Small Business Server 2003 including Microsoft SharePoint and Exchange data.


DRScanSession Utility Support for Windows XP and Windows 2003

The DRScanSession Utility is supported on Windows XP and Windows 2003 for local disaster recovery processes. It allows you to recover the local backup server from any tape media containing the backup for the server.


2.6 VSS Incremental/Differential Backup Support

BrightStor ARCserve Backup r11.5 introduces two additional backup methods that you can choose to back up.

Incremental Backup: backs up only those files that have changed since the last full or incremental backup was performed. After each backup, backed up files are marked so that they are not backed up during the next incremental backup job unless they have changed. It takes less time to process backup jobs using this method. However, to restore files from an incremental backup, you must supply both the most recent full backup and all subsequent incremental backup jobs.

Differential Backup: backs up only those files that have changed since the last full backup was performed. Because differential backup jobs do not mark files as having been backed up, the files that were backed up in the last differential job are backed up again. It takes longer to process backup jobs using this method. However, to restore files from a differential backup, you must supply only the most recent full backup and the most recent differential backup.


2.7 64-bit Support

BrightStor ARCserve Backup can now be installed on a variety of Windows 64-bit operating systems. The following 64-bit Windows platforms are supported:

The following BrightStor ARCserve Backup Agents and Options are supported on 64-bit Windows systems:

Due to architectural differences between 64-bit and 32-bit Windows platforms, various elements of 64-bit operating systems cannot be accessed by 32-bit applications. These elements include areas of the Windows System Registry, system settings files included in a System State backup, and Volume Shadow Copy Service (VSS) writers.

To overcome these limitations, and to successfully perform backup and restore operations when the BrightStor ARCserve Backup server is running a 64-bit version of Windows, the 64-bit version of the BrightStor ARCserve Backup Client Agent must be installed with the BrightStor ARCserve Backup server on a 64-bit machine.


2.8 Windows Virtual Server 2005 and Virtual PC 2004 Support

BrightStor ARCserve Backup now supports Windows Virtual Server 2005. File-system and client agents support Windows Virtual Server 2005 and Virtual PC 2004.


2.9 User Profile Utility

The User Profile Utility lets the BrightStor ARCserve Backup administrator manage user profiles and user access to BrightStor ARCserve Backup.

When you install BrightStor ARCserve Backup, the caroot user profile is the default, with the administrator group assigned to it. The Administrator group provides control over all BrightStor ARCserve Backup functions operating within a given BrightStor ARCserve Backup domain.

Using the User Profile utility the BrightStor ARCserve Backup server administrators can:


2.10 Supporting NEC CLUSTERPRO/ExpressCluster Clusters

BrightStor ARCserve Backup can be installed and configured in a cluster environment either as a CLUSTERPRO/ExpressCluster-aware application or as a CLUSTERPRO/ExpressCluster unaware application.

BrightStor ARCserve Backup is a fault-tolerant application, capable of handling failover and providing backup and restore capabilities for data residing in cluster environments.

NEC Cluster Server (CLUSTERPRO/ExpressCluster) allows multiple Windows based servers to connect with one another so that they appear to network clients to be a single, highly available system. BrightStor ARCserve Backup supports NEC CLUSTERPRO/ExpressCluster version 7.0 SE and LE.

BrightStor ARCserve Backup support for NEC CLUSTERPRO/ExpressCluster offers the following advantages:
