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 management
with backup templates
 Configuring hundreds or thousands of backup
jobs
 Backup templates to ease the pain
Maintenance Plan Designer
Adaptive Compression for small
and 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-level
recovery 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-level
recovery 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 recreate 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 be
protected.
Encryption occurs after compression, in memory, so backups remain small,
but secure

168-bit 3DES
128-bit RC4

Protect backup and restore
operations 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.

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 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
Operational reporting/Archiving/
Data warehousing
• 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
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
Centralized reporting
(Consolidation)
– Optimized block size
– Partitioning
– Other optimizations
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
