Networker Command mminfo output details meaning

mminfo output and Meaning of saveset flags:

The save set ssflags summary are as follows: CvrENiRPKIFk

C = Continued

v = valid

r = purged (recoverable)

E = Eligible for recycling
N = NDMP generated
i = incomplete
R = Raw (not for savesets backed up using rawasm)
P = snapshot
K = cover
I = In-progress
F = Finished (ended)
k = checkpoint restart enabled

The save set sumflags field summary are as follows:

The first flag in the sumflags field shows which part of the saveset resides on the specified tape. The possible values are:

c = Complete (the entire saveset resides on this tape volume)

h = Head (the head, or start of the saveset resides on this tape volume)

m = Middle (the middle of the saveset resides on this tape volume)

t = Tail (the end of the saveset resides on this volume)

The second flag byte shows the status of the saveset. We will not be using this flag in our cloning script, the possible values for this flag byte are:

b = Browsable

r = Recoverable

a = Saveset was aborted

I = Saveset is still in progress

E = Eligible for recycling

S = Saveset was scanned in

i = Incomplete saveset

The clone's clflags summary are as follows: aios

a = aborted

i = incomplete
o = opaque (NDMP clone of regular NetWorker savesets)

s = suspect (read error)

The volume's volflags summary are as follows: dr

d = dirty (in use)

r = scan and read-only

NDMP and NDMP-DSA flags:

cbN/:

         c Complete

         b Browsable

         N NDMP generated

cbNs:

        c Complete

        b Browsable

        N NDMP generated

        s NDMP-DSA

Query the media database to determine which save sets are NDMP save sets and the status of an NDMP save set in the media database. NDMP save set status information is

important when performing NDMP recoveries.

• To perform a browseable NDMP recover, the ssflags (fl) field for an NDMP save set must contain a (b). The b value denotes a brows able save set.

• To perform a save set recover from the NetWorker User program, the ssflags (fl) field for an NDMP save set must contain either (r) or (b).

• An NDMP save set contains an N attribute in the ssflags (fl) field.

• An NDMP-DSA save set contains an s attribute in the ssflags (fl) field.

In the following example, the NDMP save set status is recoverable (r). To recover the data, you can only perform a save set recovery from a command line.

In the following example, the NDMP-DSA save set status is brows able (b). Recover the data by using the NetWorker User program, or from the command line. A browseable NDMP-DSA save set supports brows able and save set recoveries.

The volume's state summary are as follows: EMXA

E = Eligible for recycling

M = Manually-recyclable
X = Both
A = Archive or migration volumes.

Data Domain Boost

What is Data Domain Boost:

                      EMC Data Domain Boost software, also known as DD Boost, is designed to offload part of the Data Domain deduplication process to a backup server or application client. That prevents the Data Domain disk array from having to carry the full burden of the dedupe workload. The software is designed to increase backup speed while decreasing network bandwidth needs. This is particularly advantageous when backups are being written to an off-site Data Domain system over a wide-area network, which may have significant bandwidth limitations.

                       Rather than sending all data to the Data Domain system for deduplication processes, DD Boost enables/install the backup server or application client to send only unique data segments across the network to the Data Domain system. This reduces the amount of data transferred over the network by 80 to 99 percent. The Data Domain Boost software provides:

Faster, More Efficient Backup: Distributes parts of the deduplication process to backup server or application client - 50% faster backups and up to 99% less network bandwidth required.

Simplified Disaster Recovery: Enables application to control Data Domain replication process with full catalog awareness.

Advanced Load Balancing and Failover: Aggregates transport links for transparent load balancing and automatic link failover.

DD Boost is integrated with the following software products:

• EMC Avamar and NetWorker
• Dell NetVault Backup and vRanger
• HP Data Protector
• Symantec NetBackup and Backup Exec
• VMware vSphere
• Veeam Backup & Replication
• IBM Data Studio
• Microsoft SQL Server Management Studio
• Oracle Recovery Manager (RMAN)
• Pivotal Greenplum Database
• SAP BR Tools and SAP HANA Studio

It is supported on the following EMC Data Domain deduplication storage systems:

Data Domain DD2200
Data Domain DD2500
Data Domain DD4200
Data Domain DD4500
Data Domain DD7200
Data Domain DD9500


Faster, More Efficient Backup:

EMC Data Domain Boost distributes parts of the deduplication process to the backup server or application clients, enabling client-side deduplication for faster, more efficient backup and recovery. With Data Domain Boost, the server only sends unique data segments to a Data Domain system. 

Advanced Load Balancing, Link Failover and Dynamic Client Routing:

The Data Domain system then transparently balances the backup load between links in the group and automatic link failover keeps backup jobs operational in case of temporary network glitches. In addition, the Data Domain system can improve network utilization by dynamically routing clients between networks.

Single point of management:

With EMC Data Domain Boost for Backup Applications, backup administrators can control replication between multiple Data Domain systems from a single point of management to track all backups and duplicate copies. 

Simplified Disaster Recovery:

This allows administrators to efficiently create disaster recovery (DR) copies of their backups over a wide area network (WAN) using EMC Data Domain Replicator as well as keep track of all the copies in the backup application’s catalog for easy disaster recovery.

Complete Application Owner Control

EMC Data Domain Boost for Enterprise Applications to provide application owners and database administrators with complete control of their own backups, using their native application utilities.

Data Protection as a Service

Data Domain Boost provides secure access to enable data protection as a service in private and public cloud deployments. For large enterprise and service provider environments, Data Domain systems provide multiple Data Domain Boost users with secure, logical data isolation and access to data.

EMC Data Domain

                 Data Domain Corporation was an Information Technology company from 2001-2009 specializing in target-based deduplication solutions for disk based backup.[1] Since its acquisition by EMC Corporation in 2009, Data Domain was founded by Kai Li, Ben Zhu, and Brian Biles.[2] Chief Architect Hugo Patterson joined 3 months after initial funding. The first product revenue was in the beginning of 2004.

                 In June 2009, EMC Corporation announced their intention to acquire Data Domain Corp for $2.4B, outbidding NetApp's previous offer.[5] In July, the two companies reached definitive agreement regarding the acquisition. Since then, Data Domain systems have been a product line brand within the EMC Core Technologies portfolio. According to IDC, EMC in 2014 captured 62.3% share of the market for purpose-built backup devices worldwide. The majority of this share was from Data Domain product revenue.

Domain systems have since significantly surpassed this capacity and speed:

	DD2200	DD2500	DD4200	DD4500	DD7200	DD9500
Logical Capacity	40-860 TB	1.3-6.6 PB	1.8-9.4 PB, 3.7-18.9 PB*	2.8-14.2 PB, 5.7-28.5 PM*	4.2-21.4 PB, 8.5-42.8 PB*	8.6-43.2 PB, 17.2-86.4 PB*

The EMC Data Domain Operating System delivers industry-leading speed and efficiency through variable-length deduplication. With performance up to 58.7 terabytes per hour, organizations can meet the most challenging backup windows while reducing backup and archive storage requirements by 10 to 30 times, making disk a cost-effective alternative to tape.

Seamless Integration

DD OS enables EMC Data Domain systems to integrate seamlessly with existing infrastructures including leading backup, archive, and enterprise applications. A Data Domain system can protect the entire enterprise including backup for Oracle, Microsoft, VMware, IBM i, open systems, big data and mainframe environments as well as file and email, database, enterprise content management, and virtual machine archiving.

Network-Efficient Replication

With the DD OS, organizations can replicate backup and archive data off-site faster, with minimal bandwidth for safe, tape-free disaster recovery. Data Domain systems provide flexible replication topologies to optimize your backups such as full-system mirroring, selective, bidirectional, many-to-one, one-to-many, and cascaded.

Reliability and Security

The Data Domain Data Invulnerability Architecture is core to DD OS and is built into every system, providing the industry’s best defense against data integrity issues. Inline write-and-read verification, continuous fault detection, and self-healing ensure that backup and archive data is accurately stored, retained, and recoverable or accessible throughout its lifecycle on a Data Domain system. Combined with the ability to meet compliance regulations and security requirements, no other storage system provides this level of protection.

Cloud Readiness

DD OS provides secure multitenancy, which delivers data isolation for enterprises and service providers looking to deploy Data Domain systems in a private or public cloud. With secure multitenancy, a Data Domain system logically isolates tenant data, ensuring that each tenant’s data is only visible and accessible to them. Multitenant management and monitoring enables chargeback, trending, and tenant-level reporting.
