More data, more storage requirements, more data retrieval and longer retention of
data have made the speed and efficiency of regular backups a vital component of
corporate IT success.
And yet, the time required for file-based data backup continues
to increase while the time allotted for it remains constant. This is a critical
issue and becomes more important when it is understood that despite advances in
backup technology, backup speeds continue to slow as a direct result of increasingly
non-optimized data on the disk.
Data backup involves file access that creates millions of I/Os to reads and write.
Each I/O represents a unit of time and a degree of latency. Backup times creep up
and quickly exceed their windows. Solutions to handle this, including more hardware,
will never be effective if the underlying cause is not eliminated or prevented in
the first place.

How can I increase the speed of my backups?
I/O optimization software, which prevents the surplus of unnecessary read and write
I/O from being created, dramatically decreases backup times. While different backup
tools will be differently affected by excessive I/O, the majority of V-locity customers
are surprised by the huge improvement in backup speeds and completion rates.
uniquely addresses the unnecessary I/O patterns of reads and writes by aggregating
data on writes to perform sequentially while caching reads on available server memory
without contention to the application. As a result, V-locity boosts application
performance by 50% or more by (1) maximizing the efficiency of every single I/O
from write requests that leave the server and (2) caching the most active data from
read requests using available server memory.
Read I/O Optimization – Much of the I/O traffic moving through
the infrastructure shares similar data, yet every byte of that data travels the
entire distance from server to storage and back for every I/O request, even when
it is frequently accessed data. IntelliMemory™ technology addresses
this read request inefficiency by caching the most active data in the server’s available
memory. Should an application require more memory, V-locity serves memory back to
the application to ensure there is never a case of memory starvation or resource
contention. Condusiv Technologies’ self-learning caching algorithms have set the
gold standard for the industry as they are OEM’d by eight of the top ten largest
PC manufacturers in the world.
Write I/O Optimization – V-locity’s IntelliWrite®
technology optimizes I/O write operations, eliminating the performance penalties
associated with the Windows OS, splitting files into pieces and writing each piece
to a different logical location within the SAN or NAS. V-locity is aware of space
allocation and aggregates writes to behave sequentially—requiring less I/O for every
file written. Subsequent reads also benefit, since only minimum I/O is required
to fulfill the request. As a result, only productive I/O requests are processed
across the entire infrastructure, enabling more data to be processed in the same
amount of time.
When only productive I/O traffic is processed through the server, network and storage, I/Os
per second are accelerated, latency is greatly reduced, and more work can be performed
in the same amount of time. This greatly improves the efficiency of all VMware ESX/ESXi
and Microsoft Hyper-V virtual platforms and physical servers for increased bandwidth.
"I've seen as much as an 88% improved backup time on one server."
