They must be able to: Provide rapid near-term recovery of data and applications to assure business continuity. Back up a growing volume of data, without interrupting normal business activities. Meet expanding data protection needs within existing budget constraints. Increasingly, IT managers are finding traditional tape media backup systems inadequate to meet their nearterm backup/restore requirements. This is due to some inherent disadvantages of tape libraries: Long Backup Windows, requiring hours per terabyte, preventing access to applications and data. Slow Restore Times, particularly when data is stored on multiple tapes that must be loaded and unloaded. Lack of Scalability, requiring purchase of additional, costly tape libraries to accommodate growth. Cost and Complexity, including high initial cost and expensive, time-consuming maintenance and management. While the longevity and low cost of tape media make it attractive for long-term data archiving, enterprises need a better solution for their short-term backup/restore requirements. This need is especially apparent when one considers that 90% of the data required for recovery has been backed up within the previous 7 days. Keeping these files on disk, ready for rapid recovery, is critical to business continuity.

Each RAID 5 pool consisted of 3 physical disks. Configured Logical Drives: LD0 148GB of RAID 5; mapped to Channel 0, LUN0; used by Server S1 LD1 148GB of RAID 5; mapped to Channel 0, LUN1; used by Server S2 LD2 148GB of RAID 5; mapped to Channel 1, LUN0; used by Server S3 LD3 148GB of RAID 5; mapped to Channel 1, LUN1; used by Server S4 4. Backup Software information Mfg: Computer Associates Product: BrightStor ARCserve 11 Version and Build: v11.0, build 2670 Part 1: D2D Backup setup Spheras RAID Watch 1.53 was used to manage the FS4500 and create RAID 5 logical drives to be used by each of the servers as backup drives in our configuration. Two RAID logical drives were created and assigned to the primary channel (Channel 0) of the FS4500, and another two RAID 5 logical drives were created and assigned to the secondary channel (Channel 1). Configuring the FS4500 logical drives 1. Launch Spheras RAID Watch and log into your FS4500 by specifying the IP address. At the main RAID View window, click the Logical Drive icon (circled in red in the figure below) to open the Create Logical Drive window. Create a logical drive and partition by selecting from the Available drives list, click Add, and select the RAID Level desired. All other parameters were left with

Using Computer Associates ARCserve 11 and Adaptec FS4500 Fibre-to-SATA RAID 4 the default settings. Additionally, you can specify which controller you want the Logical Disk assigned to using the LD Assignment field. For our test configuration, we only had one (Primary) controller. 2. After logical disks are created, they must be mapped to a LUN. From the main RAID View window, click the Physical View icon and select the channel and controller to which you wish to map your configured Logical Drives. In the example below, we ve selected Channel 0 on the Primary Controller. Next, click on the LUN Mapping tab and expand the All LDs icon to view all configured Logical Drives and partitions. Select the partition you want to map, select the appropriate LUN number desired and click OK to commit changes. In our test configuration, we assigned LD0 and LD1 to Channel 0 on the Primary controller mapped as LUN0 and LUN1, respectively. For Channel 1 on the Primary Controller, we assigned LD2 and LD3 as LUN0 and LUN1, respectively.

Using Computer Associates ARCserve 11 and Adaptec FS4500 Fibre-to-SATA RAID 5 3. To ensure each server in the configuration will detect and access only one configured RAID 5 volume from the FS4500, it is recommended that you disable the detected RAID 5 volume that will not be used. This ensures that only the desired server will have access to the desired device. To achieve this, open the Device Manager, expand the Disk drives icon, select an Adaptec FS4500 SCSI Disk Device icon, right-click and select Properties. 4. The Properties page lists the LUN ID of the device. Decide which configured RAID 5 logical drive you wish to use on each server and write down the LUN assignment.

Using Computer Associates ARCserve 11 and Adaptec FS4500 Fibre-to-SATA RAID 6 5. Return to the Device Manager window, select the appropriate Adaptec FS4500 SCSI Disk Device icon, rightclick and select Disable. In our test configuration, we disabled the Adaptec FS4500 SCSI Disk Device with LUN 1 on our S1 server. On our S2 server, we disabled the Adaptec FS4500 SCSI Disk Device with LUN 0 6. After disabling the appropriate Adaptec FS4500 SCSI Disk Device, the icon should be crossed out and Windows will not detect the device until it is enabled again. Repeat the above steps to disable the appropriate LUNs for servers S3 and S4.

Using Computer Associates ARCserve 11 and Adaptec FS4500 Fibre-to-SATA RAID 7 Part 2: Configuring ARCserve to run GFS backups Perform the following configuration steps for each server: 1. Install Computer Associates ARCserve 11 for Windows backup software. 2. Begin by determining the backup schedule and the duration to keep your data on the disk-to-disk backup device before moving it to tapes to archive it. This info is needed to create appropriate disk-to-disk backup devices. In the following example, we will use a backup schedule <5-day weekly incremental backup, full backup on Friday> with GFS enabled, which is one of the default options in ARCserve. We want to keep 1 week of backup data on the disk-to-disk backup device for fast data recovery. Based on this requirement, we need to define 6 File System Devices (FSD) in a group to hold one week s data before it is moved to a secondary medium (e.g., tape medium). (The 6 FSDs are used to hold backup from Mon, Tue, Wed, Thu, Fri and a second Fri; this will ensure a Fri full backup be available in the case of a failure occurring during the latest Fri full backup.) 3. Run Disk Administrator to configure a volume with its corresponding FS4500 logical drive. Assign a drive letter for the FS4500 logical drive. (We used i: for the FS4500 volume on server S1; j: for server S2; k: for server S3 and l: for server S4). Open Device Configuration to create the File System Devices with the FS4500 volume for backup. 4. The Device Configuration screen will appear as shown below.

Using Computer Associates ARCserve 11 and Adaptec FS4500 Fibre-to-SATA RAID 8 Tip: With the <auto naming> for media name, the start day will use the FSD named 1 ; the second day will use the FSD named 2. If the start day is Monday, then the first full backup on Friday will use the FSD 5. Tip: The file system named 6 will be used for the second Friday full backup. The Mon Thu FSDs will be reused for the incremental backups. 5. Start the tape engine again and create an FSDevice (for File System Device) group and move all the 1, 2, 6 FSDs into this group. 6. Click the Backup icon to define the <5-day weekly incremental backup, full backup on Friday> with GFS enabled with the following steps: Select the source for backup.

Using Computer Associates ARCserve 11 and Adaptec FS4500 Fibre-to-SATA RAID 9 Make sure all the FSDs are in a group named FSDevice and this group is used as backup destination. Define the backup schedule, use GFS and set parameters as shown:

Using Computer Associates ARCserve 11 and Adaptec FS4500 Fibre-to-SATA RAID 10 Enter a different name in the Media Pool Name Prefix for each application server. Set the media preservation as shown: Tip: For daily set, Mon, Tue, Wed, and Thu will be preserved for 6 days. Both Friday sets will be preserved for 13 days. (We Need 2 Fri sets in case the latest Fri full backup fails; we still have the one-week old full backup and the incremental daily backups.) Repeat the above steps for the other servers to complete the D2D backup setup. Now the four application servers will run the scheduled jobs to perform D2D backups. The FS4500 will hold up to two weeks of data before being re-used to backup newer data. If data must be archived, backups must be moved to secondary medium weekly, before the older backups are overwritten. Part 3: Restore procedures To restore a backup job, use the following procedures: 1. Click Restore under Quick Start.

Using Computer Associates ARCserve 11 and Adaptec FS4500 Fibre-to-SATA RAID 11 2. From the Restore configuration screen, click Source to view the backup jobs available for restore. You can customize the view by changing the Restore by type selections. 3. In the example shown, we ve selected Restore by Session and selected all files backed up in a backup session to be restored.

Using Computer Associates ARCserve 11 and Adaptec FS4500 Fibre-to-SATA RAID 12 4. Click the Destination tab to configure destination parameters. By default, the Restore files to their original location(s) box is checked. If you want the files restored to a different location, uncheck the box and select desired destination. 5. Click the Schedule tab
