“TSM is the granddaddy of unified recovery management”
-- Lauren Whitehouse, ESG
Explosive data growth along with shrinking backup windows and reduced recovery times
has precipitated the deployment of different technologies like block-level backup,
snapshots and continuous data protection. The emergence of these new data protection
technologies has prompted manufacturers to develop unified recovery management
platforms.

Manage 4x* as many objects as the industry-leading TSM 5.5
– At least double the internal database size (from 512GB to 2TB, minimum)
– Support for at least 2 billion objects* with a single TSM server
– TSM integrates with TSM Fastback to successfully manage and protect remote office
data
Run an increased number of concurrent operations*
– 9x increase in the size of the internal Recovery Log enables running more backup jobs
from a greater number of clients, and/or an increase in the size of existing backup jobs
– Result = Potentially shorter backup windows
Customer Benefits: Scalability Improvements
TSM 6 can effectively
meet the challenges of
the „tidal wave of data‟

* Results will vary depending on user’s environment, systems/processors, type of data,
expiration policies, data change rates, etc.
Storage Manager 6
TSM version 6.1 was a significant change to the underlying architecture of TSM version
5 because it replaced the catalog of the TSM server with IBM’s enterprise class DB2
relational database system. The introduction of DB2 has brought many improvements to
TSM, for example the TSM DB2 database can manage the four times the number of
objects that version 5 could allowing the database to scale to 2 terabytes in size versus a
practical limit of about 150 gig with version 5. These result in fewer TSM servers to
manage the same amount of data, also the recovery log is now 9 times larger.

Improvement in backup performance demonstrated in the lab for multiple clients backing up small files
– Improved backup throughput may reduce backup windows and/or increase the workload that can be managed within existing window
Improve Recovery Point Objectives for DR planning
– Addition of Active Data Pools to Disaster Recovery Manager (DRM) in Tivoli Storage
Manager 6 Extended Edition
– Track, manage and recycle active-data pools as required by policies
100% improvement* in expiration processing
– New granular expiration process and parallel process execution
– Fine-tune expiration policies by specific client nodes, node groups, or nodes
belonging to a specified domain
Customer Benefits: Performance Improvements

* Results obtained in lab conditions for multiple clients backing up small files. Customer results will vary
depending on environment, systems/processors, type of data, expiration policies, data change rates, etc.
Meaning that significantly more jobs can run concurrently allowing more work to be
completed in a shorter period of time and the performance of backing up small files and
database expiration processes has also improved dramatically.

Tivoli Storage Manager 6 Extended Edition includes data deduplication for sequential-access disk pools, at no extra charge
Improves recovery times relative to recovery from tape as many more recovery points can be stored on disk; or reduces the amount of capacity needed
Operates as a post-process / no impact on backup performance / automatic space reclamation
Complementary with the IBM TS7650G ProtecTIER Gateway
– TSM 6 built-in data deduplication and the TS7650G ProtecTIER Gateway can coexist to meet different customer needs
New Built-in Data Deduplication
Customer Benefits: Enhanced Data Reduction
Tivoli Storage Manager 6, combining progressive incremental data
capture with data deduplication, does a better job of reducing storage
capacity requirements than pure data deduplication solutions
Finally, in an effort to deal with explosive data growth, TSM 6.1 took disk-to-disk
backup to a new level by introducing server side data deduplication.

Functions / Topics v6.2.1
Windows Backup/Archive Client Support for GPFS 3.3
Higher Limits on TXNBYTELIMIT and MOVESIZETHRESH parameters
Windows Passthru Driver
Automatic Deployment for Windows Clients
TSM for ERP: Improve TSM Handling of Very Large Objects
Microsoft Hyper-V full Guest Backup Using Volume Shadow Copy Services (VSS)
Simultaneous Write During Storage Pool Migration
Concurrent Access to Centera Volumes
Auto-discovery of New VMware Guests
VCB Gen II - VMware vStorage for Data Protection API integration
Security: In Flight Data Encryption Using SSL
Client-side Data Deduplication
Incremental Backup of Windows System State
Now let us discuss TSM version 6.2. TSM version 6.2 has delivered on a number of new
features and for the sake of time, I will only address a few of these in detail but I will run
down the list first. Windows VA client 4 for GPFS 3.3. In the past there was support for
only AIX and Linux. Higher limits for transaction byte limit and move size threshold
parameters which helped take advantage of high-speed tape drives and the limit has been
increased to 32 gig. Windows pass through drivers allow you to install the native
Microsoft driver since TSM device drivers are not supported drivers. There are
considerations for both approaches, which should be researched before implementing one
or the other. Automatic deployment of windows clients, TSM for ERP, which has
improved the handling of very large objects, which can reduce the possibility of the TSM
recovery log being corrupt, full backup support for Microsoft Hyper V, VSS and
simultaneous rights during storage pool migrations and concurrent access to Sentara
volumes, which works the same as the concurrent access TSM gate to the file device path
in version 5.5, auto discovery of new VMware guests, VCB generation 2 support, which
is now called the V storage API for data protection, SSL support and in addition to server
side data deduplication, TSM version 6.2 now can do client side deduplication to further
reduce the amount of data that must be processed, incremental backups of the systems
state can be conducted with can reduce a lot of backup activity especially with Windows
2008.

The name of the game today when protecting data is data reduction, the less data you
have to store, the better your data protection coverage is. TSM has a history of reducing
storage requirements with a progressive backup methodology also known as the
incremental forever for backup. Now TSM can further reduce storage requirements with
its client side and server side data reduplication capabilities.

original file
LAN / WAN
TSM Client Deduplication
TSM client side deduplication uses a file device flat storage pool on the TSM server with
de-dupe turned on so redundant data is filtered off before it is sent to the server and there
can be many benefits to the setup such as reduced network traffic, faster backups, and
reduced storage pool consumption.

TSM Client Side Data Deduplication
One of the benefits of client side deduplication is to provide global de-dupe and so if
client B has the same files as client A TSM wont backup the redundant files from client
B. Data that is copied from a TSM storage pool to a physical tape is rehydrated.

Simultaneous Writes During Storage Pool Migration
Part of the challenge today is making a DR copy in a timely manner before they pickup.
Simultaneous rights will allow you to make the DR copy at the same time you are
migrating your data or writing data to the active data pool.

VMware: Off Host Backup Enhancements Auto Discovery of new VM guests
Leverage vStorage API for Data Protection for file-level backup & recovery
– LAN-free backup of virtual machines from a centralized proxy server
– (VMware released v1.5 of Consolidated Backup Framework which supports
legacy VCB operations with ESX/ESXi 4.0)
Benefits:
Eliminate manual processes for tracking VM guests
Low impact backup and recovery
Auto discovery of the new VMware guests allow TSM to be aware of new guests that
have been added to the ESX server for backup purposes, thereby minimizing the risk of
VMs and not being backed up or by reducing the possibility of overloading the system by
having to catch up from VMs that have not been backed up at all.

Since TSM uses DB2, DB2 has the ability to conduct log shipping between two
databases. This allows the TSM server to replicate its database to another TSM server,
which can greatly speed up the ark since the TSM server does not have to have its
database resorted.

Released on March 13 of this year is the new TSM for virtual environments. TSM for
VE uses the V storage API to make a single pass of the VMBK while delivering volume
image of file level recovery and additionally change block tracking is supported so
backups are faster since less data is backed up. The data that is backed up can be de-
duped by TSM’s client side dedupe technology.

It will have several new interesting features and an exciting feature for those who are
trying to improve the DR recovery objectives and to get away from handling physical
tape will be the TSM server replication at the node level with deduplication and today the
TSM server can copy its storage pool to another TSM server or variety but must
rehydrate the data first. Now bandwidth can be saved with deduplication and replication
can be done at the node level and not at the storage pool level and more importantly
DRTSM servers are active for the replicated data at the DR site is readily available.

Faster TSM Internal Database Backup
Faster backup and restore of TSM internal database
• Parallel streams for backup/restore processing give improved throughput
• Reduced time for database backup/restore
• Increased scalability of TSM server without expanding database backup window
•Before
•After
Since there is more data in storage pools, TSM databases are getting larger which is
therefore taking more time to back them up and today only backup stream can be initiated
and so if there are multiple tape drives available they cannot be used to increase the
backup throughput of the TSM database.

Since TSM licensing is based on the number and type of processors and cores of the
servers as protected, customers have had struggles keeping track of the processor counts
for TSM licensing purposes. There will be now be a processor value in a report which
will help with license compliance.
