HyperBac for Sybase |
What is HyperBac for Sybase and how does it
work?
|
HyperBac for Sybase is an enterprise backup and archival
solution, for your Sybase environment. Working with your existing backup
techniques, HyperBac uses high performance lossless compression to reduce the
size of your backup data sets by up to 90% and the time taken to perform your
backups by up to 50%.
The HyperBac benefit (and hence its capacity to scale to enterprise use) is
that it provides the appropriate balance between maximizing compression,
ensuring transaction throughput and minimizing operation times.
In practical terms, this means that HyperBac ensures a high transaction
throughput during operation, no CPU bottlenecks and a shorter operation window.
HyperBac works with the resultant backup information stream and thus it
seamlessly integrates with Sybase's native backup procedures. To that extent,
the database administrator does not need to change their existing scripts or
deal with another application layer to use HyperBac.
As importantly, HyperBac does not directly read or write data from or to your
Sybase database, therefore you can be assured of information integrity at all
times.
In addition archive files created by HyperBac can be converted to native backup
files (physical or logical) at any time on any system, offering peace of mind
for customers as well as a viable alternative recovery path should the restore
or import occur on a system which does not have HyperBac installed.
Last but certainly not least, HyperBac has integrated AES (128/192/256 bit)
encryption to protect your backup sets.

What technical advantages will HyperBac for
Sybase deliver?
|
HyperBac for Sybase delivers a number of technical advantages.
Solution performance means that there is less contention for resources on the
system(s) during backup operations. The advantage here is that you can avoid or
avert the need to re-schedule or partition your backup operations to cater for
end user requirements.
As your data storage grows, so to will your backup times. HyperBac gives you
immediate relief from these growing pains. As well as prolonging the value of
your existing infrastructure, HyperBac also allows you to maintain existing
procedures and scripts for as long as possible. The advantage there is reduced
change management risk and need for support.
Consider the following simple example. Your backup window can no longer
accommodate your nightly incremental backups. The issue is serious as other
batch transactions such as general ledger consolidations and invoice runs
cannot be re-scheduled or changed. One unpalatable response to this situation
is to split the backups and target different database objects for different
nights. This means risk and greater loss of data in the event of disaster.
A far more appropriate option in this circumstance is to deploy HyperBac to
reduce both your backup times to cater for the existing window. The additional
benefit is that your backup will be significantly compressed, freeing physical
storage resources as well.

Does HyperBac for Sybase require me to change my
existing backup scripts?
|
Not at all.
HyperBac for Sybase is designed to work with your existing scripts or with
Sybase Central wizards. The only thing required is to point your dump device
(or output file) to a HyperBac registered destination.
Integration Example 1 - Working with specific file extensions
You perform a dump that writes a file called mybackup.bak. Just change the
filename to mybackup.hbc or mybackup.hbe (file extensions which are built in
recognised HyperBac archive files)
That is all that is required. Change the file extension and HyperBac will
recognize it. In the above scenario we used the default extensions hbc (for
compression only) or hbe (for compression and encryption). In fact, you can
configure HyperBac to nominate any file extension you wish, for example if you
wanted all .BAK files created by Sybase to be compressed and encrypted by
HyperBac, you would simply register the .BAK extension with HyperBac.
Integration Example 2 - Working with specific directories or paths.
Let's take the above example and say that you write your backups to the
following path and file /mydatabase/backup/mybackup.bak
If you don't want to change your scripts at all, then you can configure
HyperBac to recognize the path /mydatabase/backup. That means that all files
written to that path (irrespective of their name or extension) will either be
compressed and/or encrypted, depending upon what you choose.

|
Will HyperBac for Sybase cause me to change my
disaster recovery policies or procedures?
|
No.
But it will give you options that you previously didn't have. By reducing your
backup size you can keep more backups online. That gives your flexibility and
options during recovery. As importantly, it saves you time during recovery,
because you won't have to rely on fetching tapes from off site locations.
You'll reduce risk. Why? Because you'll have more backup sets online and on
your site, which can be validated at greater frequency. This is not always
possible or feasible with off site archives. As importantly you can almost
eliminate the inherent risk associated with failed tape media.

|
Will HyperBac for Sybase impact the integrity of
my database?
|
Not at all.
HyperBac for Sybase works with the existing native APIs to read and write data
to and from your database. For example, if you are using the Sybase Central
wizards, then all you need to do is point your dump device to a HyperBac
recognized path or file type. The fact remains that you are still running the
native Sybase commands at all times.
Therefore HyperBac does not interfere with normal database operation in any
way. As importantly, HyperBac will operate independently of the database
release you have deployed.

Can I restore or import HyperBac created
archives without HyperBac?
|
HyperBac for Sybase is shipped with an royalty free extraction
utility, which is a simple command line utility for Linux and Unix
installations. Similarly, it is deployed as a graphical tool as well as a
command line utility for Windows installations.
In short, the extractor allows you to take an existing HyperBac backup and
transform it into the native database format. There are many benefits to this
facility.
1. You can transport compressed and/or encrypted backups (securely and
without unnecessary bandwidth demand) to remote sites and then simply use the
extractor utility to transform the backup set to native format. This has
application to those who replicate testing or development environments.
2. The extractor utility can expedite and lower the cost of server
migrations or consolidations.
3. The extractor also serves to give you peace of mind. You can continue
to work with HyperBac backup sets irrespective of whether or not the product is
deployed. In short, we recognize the importance of vendor independence as much
as you.
These are just three examples; however there are many more that simply depend
upon your imagination and business circumstance.

How does HyperBac for Sybase improve
transaction throughput during backup operations?
|
HyperBac for Sybase delivers an improvement in transaction
throughput by up to 10 times during the backup process in contrast to
comparable conventional backup operations. This is due to the substantial
reduction in write disk I/O during the HyperBac backup process.
With regard to performance on Sybase systems, HyperBac delivers greater
compression and takes no more time than a compressed database dump (level 1).
Similarly, it delivers equivalent compression at considerably less time than
the level 9 compression capabilities within Sybase.
For those using the Sybase Central BACKUP command, then HyperBac delivers 90%
compression and reduces the time taken by up to 50% against the native command
performance.

|
Does HyperBac for Sybase support backups direct
to tape?
|
Not at present.
However HyperBac backups and archive files are inherently compressed/encrypted
so the images written to tape are up to 5 times smaller than equivalent backups
direct to tape.
Disk based backups provide database administrators with fast, reliable recovery
online points. HyperBac's compression is superior to the hardware compression
which is common on many tape devices, so a disk to tape backup strategy will
generally yield a 50% reduction in tape storage costs as well as a 75-90%
reduction in DASD, NAS or SAN requirements.

Can I still perform native Sybase backups?
|
Yes.
Using HyperBac does not limit the type of backup you perform, the media to
which you write it or the vehicle you use to perform the operation.
With regard to performance on Sybase systems, HyperBac delivers greater
compression and takes no more time than a compressed level 1 database dump.
Similarly, it delivers equivalent compression at considerably less time than
the level 9 compression capabilities within Sybase.
For those using the Sybase Central BACKUP command, then HyperBac delivers 90%
compression and reduces the time taken by up to 50% against the native command
performance.
As importantly, HyperBac gives you the ability to compress your logical
backups, which is an important value add to native Sybase capability.
Last, but certainly not least, all of this functionality is delivered with
integrated AES Encryption to help you protect your backups against both server
and network vulnerabilities. Not to mention, the compliance expectations that
are growing by the day.

How is HyperBac for Sybase licensed?
|
HyperBac for Sybase is licensed by the physical Sybase server.
That is, the machine(s) on which you are running your database instance.
HyperBac is essentially priced and licensed to give you exceptional value for
money and pay back it's investment in months.
Let's quickly explain what HyperBac does NOT impose upon you.
1. No additional charges are required for the number of databases or
instance on the server.
2. No additional charges are required in accordance with the size of
your backup. Whether its 1 gigabyte or 20 terabytes then the investment is the
same.
HyperBac is designed to save you money and time. The licensing model is also
designed to reflect that ideal.

I don't want to change my existing backup
solution for Sybase
|
No need to.
Just as HyperBac works with the native Sybase DUMP and BACKUP commands, it will
equally work with other agent based products such as Backup Exec from Symantec.
If your present backup solution writes to disk, then HyperBac will simply
integrate with it without you having to change the application or underlying
infrastructure.
HyperBac is not designed to displace existing backup techniques rather it is
designed to enhance them.
