Introduction to the DR Series System 1 The DR Series system documentation contains topics that explain how to use the Dell DR Series system to perform data storage operations and manage storage and replication containers. The DR Series system topics introduce and describe the DR Series system graphical user interface (GUI) that you can use to manage your backup and replication operations.
• Any media that ships with your system that provides documentation and tools for configuring and managing your system, including those pertaining to the operating system, system management software, system updates, and system components that you purchased with your system. NOTE: Always check for documentation updates on support.dell.com/manuals and read the documentation updates first because they often supersede information in other documents, and contain the latest updated versions of the documents.
Understanding the DR Series System 2 The DR Series system is a high-performance, disk-based backup and recovery appliance that is simple to deploy and manage, and offers unsurpassed Total Cost of Ownership benefits. Features such as innovative firmware and an allinclusive licensing model ensure optimal functionality and the assurance of no hidden costs for desired future features.
• Simple management interface (using the system GUI) • Wide variety of data backup installations and environments The Dell DR Series system contains data backup and management software preinstalled on a Dell hardware appliance, which provides you with a robust disk-based data backup capability installed on a deduplication-enabled appliance.
• DR4100 system—which consists of preinstalled DR4000 system software on an modified Dell R720xd appliance platform. Internal Drive Capacity The capacity values listed in Table 1 represent the internal drive and available physical capacities that have been adjusted for the associated overhead in the DR4000/DR4100 system releases. NOTE: In Table 1, the abbreviations TB and GB represents Terabytes and Gigabytes in decimal values, and the abbreviation TiB represents Tebibytes in binary values.
the best results for routine and repeated data backups of structured data. Block-level deduplication works efficiently where there are multiple duplicate versions of the same file. This is because it looks at the actual sequence of the data– the 0s and 1s–that comprise the data. Whenever a document is repeatedly backed up, the 0s and 1s stay the same because the file is simply being duplicated.
During replication, the system processes data storage requests from a specified source to a specified destination (also known as a target) that acts as a replica of the original source data. NOTE: Starting with Release 2.0, the DR Series system software includes version checking that limits replication only between other DR Series systems that run the same system software release version (DR Series systems running Release 2.0.
tape backup to the original location; first, restore the data back to a DR Series system replica container, and then restore it back to the original source location of the data on the other side of the WAN link. NOTE: If you choose to use this alternate workaround method, you must set up a new data storage unit in the DMA and import the images before a restore to the original location can occur.
Using its deduplication and compression technology, DR Series systems can help achieve an expected data reduction ratio of 15:1. Achieving this reduction in data means that you need fewer incremental storage operations to run and it provides you with a smaller backup footprint. By removing redundant data, DR Series systems deliver fast reliable backup and restore functionality, reduce media usage and power and cooling requirements, and improve your overall data protection and retention costs.
One system acts as the source and the other as a target in this replication pair (for example, acme-west and acme-east). When this type of relationship exists between distinct containers on two distinct DR Series systems, it can be considered bidirectional in the sense that: • The West1 container on the acme-west source system can replicate data to a separate East1 container on the acme-east target system.
5. Delete the replication relationship and re-create a replication relationship (restoring original source and target destinations). Under this scenario, a fraction of the data to be recovered is sent across the WAN link. This could speed up a remote restore significantly. However, there are some downsides to this type of scenario: • • • If step 1 is not followed correctly, any changes not fully replicated are lost.
system (or portion) that is mounted can be accessed using the privileges assigned to each file. The NFS protocol supports Unix, Macintosh, OpenVMS, and the Microsoft Windows operating systems. CIFS The Common Internet File System (CIFS) remote file access protocol is one supported by the DR Series system, and is also known as a Server Message Block (SMB). SMB occurs more commonly than the Network File System (NFS) protocol on systems that run the Microsoft Windows operating system.
default ACL is the same as that which would be created by a Microsoft Windows 2003 Server. Therefore, these new containers with the default ACL support the following permission types: NOTE: Any user that is part of BUILTIN\Administrators can edit ACLs on CIFS shares. The local DR Series system administrator is included in the BUILTIN\Administrators group.
For any existing containers that were created prior to Release 1.1, all files are accessible to any user that logs in to the designated DR Series system. The associated ACL in these existing pre–1.
(NTFS) uses ACLs as part of the security descriptor (SD) process, which requires permissions to access such filesystem objects as files and directories. ACLs support two levels of users: • Owners • Groups Both Owners and Groups have Security IDs (SIDs) that define and identify an object owner or the group owning an object.
exists, only the pointers need to be updated on the DR Series system, and the duplicate chunk of data does not need to be transferred to the system. This process provides two benefits: it improves the overall backup speed, and also reduces the network load.
– Copy or duplicate it • If NetBackup, using the OST API, directs the DR Series system to expire a stored file, it deletes it from its filesystem. • Similarly, if NetBackup, using the OST API, wants to restore from a stored file, it directs the DR Series system which file to restore, which then delivers the stored file to NetBackup for the restore. NOTE: OST contains a feature called optimized duplication.
• Optimal supported aggregated throughput rates: – 3 Terabytes per hour (TB/hr) for passthrough write operations – 4 TB/hr for optimized write operations NOTE: Passthrough writes are when data is sent from a media server to the DR Series system without applying any optimization to the data. By contrast, optimized writes are when data is sent from a media server to the DR Series system after optimization is applied to the data.

Understanding OST Plug-In Diagnostic Logs There are currently two supported types of OST plug-ins for which you can collect diagnostic logs: NetBackup and Backup Exec. NOTE: The directory location, C:\ProgramData, is considered to be a hidden directory on Windows-based systems. However, you can copy and paste C:\ProgramData\Dell\OST\log\ into your Internet Explorer Address bar or you can enter this into the Windows command prompt window (Start→ All Programs→ Accessories→ Command Prompt).
Rotating OST Plug-In Logs for Linux If you set the OST plug-in log level to Debug, this can cause the plug-in log to quickly grow in size. The best practice for preventing any issues with log sizes is to rotate the OST plug-in logs using the logrotate utility that is commonly available on Linux-based systems. To configure log rotation, complete the following: 1. Create a file in /etc/logrotate.d/, name it “ost”, and add the following entries: /var/log/libstspiDell.
example, if the following is a core_pattern from a DR Series system (/var/cores/core.%e.%p.%t), then all the core files would reside in /var/cores. Dell recommends that if core_pattern on the client is set by NAT to a specific directory, then the diagnostics script has to look into that directory for any related cores.
• If the system is unresponsive, force the crash of pvlsvr.exe and bengine.exe, and complete the following: a. Open Task Manager. b. Locate the process. c. Right-click, and select Create Dump File. d. Retrieve the dump file from the location specified in the dialog that displays after the dump file is created.
