Say Thank you to Volunteers:

They spend their FREE time to give you this event.

Because they are love our COMMUNITY. Because they want YOU

to learn from the BEST IN THE WORLD.

If you see one of these guys in the hall – buy them a beer/wine, they deserve it.

High-speed SQL Server backup, compression and restore

Challenges

Raw data exceeds available storage space Improper use and management of differential backups Too many backup jobs and maintenance plans Backups impacting database applications Not testing all restore scenarios

LiteSpeed Architecture

User Interface

Faster and smaller backups with LiteSpeed’s Fast Compression

Determining the best differential backup schedule is challenging and poses risks for restore time objectives (RTOs)

Needing more than one backup for a restore operation is a management challenge

Backup retention on disk is more difficult Smart Cleanup technology

Easy backup job managementwith backup templates

Configuring hundreds or thousands of backup jobs

Backup templates to ease the pain

Maintenance Plan Designer

Adaptive Compression for smalland fast backups Which compression level should you select? Finding the best compression level can be a difficult

task. Backup Analyzer Adaptive Compression to the rescue

Automated Restore for easy refreshes, restore testing and checking database consistency

DBAs often contend with three restore scenarios that can be quite time consuming to implement:

• Keeping a secondary database instance refreshed with production database backups

• Testing backups to ensure they can be restored and running DBCC CHECKDB on the restored database

• Restoring multiple databases in a single pass

Automated Restore

LiteSpeed offers three restore types:

• Restore only the most recent full backup

• Restore the most recent full backup plus the most recent differential

backup, if one exists

• Restore the most recent full backup, the most recent differential if one

exists, and any transaction logs

Optionally, you can tell LiteSpeed to run a database consistency check (DBCC CHECKDB) against

each restored database and automatically drop the database upon a successful restore (restore

testing) for automatic cleanup.

Object, data, transaction-levelrecovery to minimize downtime

DBAs are often asked to restore individual objects to a database, restore old data or simply undo a recent T SQL “event.”

The problem with this solution is not that it doesn’t work — it does, the problem is quite time-consuming

Object, data, transaction-levelrecovery to minimize downtime

LiteSpeed includes a few different ways:

Object-Level Recovery (OLR) to recover objects and data.

SELECT from backup to query backups directly Transaction Log Reader to undo and redo

transactions

 Object Level Recovery

Load a backup or a set of related backups, review the list of tables,views, functions, procedures, etc. and quickly generate the DDL script to re-create the object. If it’s data you’re interested in, you can preview the data from any table or recover these objects to a database.

Transaction Log Reader

Encryption to protect your data

Companies might also have compliance regulations in place that require their data to beprotected.

Encryption occurs after compression, in memory, so backups remain small, but secure 0.5 percent increase in CPU using AES-256

40-128-bit RC2168-bit 3DES128-bit RC4128-256 bit AES

Protect backup and restoreoperations with Network Resilience

A problem with your network or disk can easily cause a backup or restore to fail immediately.

LiteSpeed’s Network Resilience No need to restart the backup. No need to restart the restore. LiteSpeed’s copy resilience for Log Shipping

SharePlex for SQL Server – use cases

Affordably replicate Oracle data to Microsoft SQL Server on-premises, remotely or in-the-cloud for special purposes:

• Improve performance of Oracle OLTP systems by offloading reporting• Harness real-time reporting and data warehousing• Affordably archive historical data• Optimize analytics and the use of business intelligence applications• Minimize downtime associated with migrations

Offload reporting, archiving, data warehousing

Data integrationCentralized reporting (Consolidation)

Data distribution/ Distributed processing

Migrations

Oracle SQL Server

Offload operational reporting for better performance

• Optimized SQL Server reporting environment with different storage layouts, indexing, and more.

• Selective down to:– Schemas and/or tables– Columns and/or rows

• Archive to SQL Server systems to allow the OLTP to run lean with high performance

• Load isolation provides more consistent response time experience than possible with any vertical upgrade

Operational reporting/Archiving/ Data warehousing

Effective and efficient centralized reporting and consolidation

• Simple consolidation to supply downstream extract processing

• Archiving, data store, data warehouse, or business intelligence repository

• Custom database configuration– Different indexes

– Optimized block size

– Partitioning

– Other optimizations

Centralized reporting (Consolidation)

Reliable data distribution and distributed processing

• Optimized SQL Server environment with different storage layouts, indexing, and more.

• Provide only the data required in the select locations

• Selective down to:– Schemas and/or tables– Columns and/or rows

• Unlimited number of targets and scaling

• Provides local copies

• Provide better response times

Data distribution/ Distributed processing

Near real-time integration with change data capture (CDC)

• Provides near real-time access to Oracle data in a SQL Server database configured for BI Analytics or reporting

• Separates operational and analytical systems thus improving performance

• Cost effectively grow and expand infrastructure

• Integrate applications that run Oracle and SQL Server with SharePlex passing data near real-time from Oracle to SQL Server.

Heterogeneous migrations:Oracle to SQL Server

Value of SharePlex in migrations:• Dramatically reduce downtime

• Return control of schedule to users

• Automatically validate data

Traditional cross-platform migration methods require downtime:

• Export/Import data

• Rebuild the database

• Verify the migration
