<strong>Unify</strong> <strong>Your</strong> <strong>Backup</strong> <strong>and</strong> <strong>Recovery</strong> <strong>Strategy</strong> <strong>with</strong> <strong>LiteSpeed®</strong><br />
<strong>for</strong> <strong>SQL</strong> Server <strong>and</strong> <strong>LiteSpeed®</strong> Engine <strong>for</strong> Oracle<br />
USING LITESPEED: REAL-WORLD EXAMPLES<br />
To wrap up, I offer several scenarios I have addressed <strong>with</strong> LiteSpeed.<br />
Need Both Compression <strong>and</strong> Encryption but<br />
<strong>Backup</strong> Window is Short<br />
This is the most frequent scenario. Most of our “in-scope of compliance”<br />
applications have large databases <strong>and</strong> are very busy, <strong>with</strong> a limited window of<br />
availability <strong>for</strong> backups <strong>and</strong> other maintenance. There<strong>for</strong>e, we need the backup<br />
completed as quickly as possible, while at the same time ensuring it is encrypted<br />
<strong>and</strong> compressed to reduce storage needs.<br />
LiteSpeed is the best choice <strong>for</strong> us in this scenario. LiteSpeed encrypts both our<br />
Oracle <strong>and</strong> <strong>SQL</strong> Server databases to the same encryption level, <strong>with</strong>out the need<br />
<strong>for</strong> extra-cost Oracle options, <strong>and</strong> compresses them to about 10-30% of their<br />
original size—just as fast as the uncompressed, unencrypted native backup utility<br />
(<strong>and</strong> often faster).<br />
Need Compression <strong>and</strong> Have Plenty of Time<br />
We do have some large databases that see relatively light use. This is typical when<br />
an application stores a lot of data but accesses it infrequently, such as lookups on<br />
an historical billing database.<br />
In these cases, our primary goal is to reduce the storage needs of the backup as<br />
much as possible. There<strong>for</strong>e, we want to maximize the compression, even if that<br />
means increased elapsed time <strong>and</strong> processor utilization. LiteSpeed addresses<br />
this situation nicely by allowing us to configure a higher compression level on<br />
both plat<strong>for</strong>ms.<br />
Need Speed More than Anything Else<br />
In some cases, the elapsed time of the backups is causing us the most pain. The<br />
speed of a backup depends on the size of the backup, disk I/O speed, processor<br />
speed, system utilization by other processes, <strong>and</strong> the compression <strong>and</strong> encryption<br />
levels. In most cases, we can achieve the fast backups we need <strong>with</strong> LiteSpeed by<br />
using the minimum compression level <strong>and</strong> no encryption. In fact, sometimes the<br />
backups are dramatically faster.<br />
