ZDLRA -- Zero Data Loss Recovery Appliance "Fast. Integrated. Zero Data Loss" Engineered for Data Protection !

We can't underestimate the importance of backup and recovery in our business lifes. Actually not only for business, but for personal life, as well..

In this blog posts, I will be concantrated on the business side of course :) I will introduce you an end to end solution for the business side, specifically for the Oracle database administrators.

As you know, backup and recovery are the most important things for DBAs.
As a DBA, you can't just say "I don't have any backups to restore or used for recovery".

If the backup and recovery is in our responsibility, and if there's a problem with the backups of production environments when there is a need to restore, then it means we are in a real throuble.

That is, if it is our responsibility to manage the Oracle database backup and recovery, then we don't have any such luxuries like not having yesterday's backup, or having a corrupted backup when it is required to be used.

This is also very important for IT managers and directors, as backup and recovery is their responsibility in the first place.

Recovery is also important as much as having backups. It must be ensured that our backups can be restored and used for the recovery purposes quickly to comply with the SLAs.

Backups should be taken continously and the checks should also be continous for ensuring the recoverability all the time.

In order to fullfil these important requirements , we use backup recovery tools.. So we need to have them, and we need to use them properly, efficiently.

We need  to schedule our backups, store them on disks, later on tape and restore them from there when necessary. We should be able to integrate several 3rd party backup solutions, we need to make them integrate with RMAN scripts, database storage policy, retention policies and so on.

We should install the tools, configure them, integrate them,  use them, and manage them and etc :) Lots of things to do and to manage right? :)

From this perspective, we need to be both responsible and well skilled.

However; eventhough we do all that we can, we may still have hard times when there is an urgent need to restore our backups.. As we can't backup continously , we may have gaps in our backups and we live with that risk time to time.

Even if everyting is in place, we may have a performance impact in our production database systems, while following these strictly defined backup policies.

In this backup tasks, and in this data lifecycle management mechanism, there are also invisible areas for DBAs. As a DBA and system admin, most of the time we can't even answer to the basic questions like where is your backup stored?  Which tape do you need to use for recovering last week's backup and so on..

There are many more things to consider, but I will stop now :)

I know I m a little pessimistic about these subjects, but these are the facts when using the traditional backup solutions.

Okay.. Here comes the solution to all these problems : Oracle Zero Data Loss Recovery Appliance,
by short name : ZDLRA.

ZDLRA is engineered for Data Protection! It is based on Exadata X8! -- Think about Exadata 's Flash.. Exadata 's I/O throughput and Exadata internal network bandwith (we have even RDMA over converged ethernet now)

Almost all the database versions are supported -> Supports 11G, 12C, 18C and 19C.
It eliminates Data Loss by providing real-time protection .. That is, it acts like a dataguard destination and continously backup the redo changes. (This is called Continous Redo Transport)

ZDLRA eliminates the production impact and reduces both the backup restore/restore times and complexity..  It backs up the changed data only and stores it in an intelligent way , so it restores efficiently. We can also offload our tape backup processes to this machine. (we can even deploy backup agents on it)

ZDLRA Delivers Cloud scale protection... That is, ZDLRA has the ability to serve data protection to thousands of Databases. It has the ability to scale without downtime.
We use a Policy based data protection in ZDRLA and we have an end to end visibility + control over the protected databases.

ZDLRA protects from disasters. It can replicate data real-time to remote ZDLRA environments and cloud.. This feature is an addition to the tape archival.. These replications are done transparently and in the background.

Lots of things to mention when it comes to ZDLRA. The technologies like delta push , delta store.. The incremental forever strategy, and more..

Well. So far so good... I think I have done an adequate introduction and now I leave you alone with my presentation about ZDLRA :)
