3 minutes with...Dhammica De Silva.

Hi all,

I posed some questions to industry experts I've have the pleasure of working with directly or have otherwise known. I think it's really useful to get ideas, communicate and ensure we learn from one another. 

Here's a 3 minutes with Dhamnica De Silva, NetBackup Engineer,
Macmillan Publishers Ltd (MPL)

What are the limitations/problems in backup & recovery at the moment? 

Disks are getting faster, cheaper bigger so users are keeping more and more while backup windows remain unchanged.

If you're a vendor, how does your company plan to deal with the problem?
If you're a customer, how are you hoping the vendor will deal with the problem?

Symantec give us Deduplication to reduce the backup footprint on disk and on the network from the client through to media server. There is less data to move. In the same way the NetBackup Accelerator enables us to create full backups using previous full backup plus incremental changes, creating a new synthetic full. We are working with these now and are generally pleased but that’s not to say that we are over the moon and without problems, there are server resource issues when writing the DD backups and further delays when ultimately duplicating this DD data to tape (where it has to be reflated)

What are the best things in backup/recovery at the moment?

Clever technologies allowing us to do more for less. Interested in Cloud backup solution if the cloud doesn’t end up dead in the water, it seems so simple. It seems that in backup terms we are going back and re-inventing the wheel and wandering why we  didn’t  do that in the first place all those years ago. As an example take Deduplication which I’m told has been available for years and years on mainframe systems.

What was your journey into backup & recovery?

I started out (way back in ’86) as a computer programmer in Greece, writing accounts and other custom packages,  but gradually got involved with systems software and eventually (in 1999) was asked to take on the Company’s new project --- NetBackup and have been doing it ever since.

Where do you see backup/recovery going in the next 10 years?

I have already mentioned cloud solutions, but I see more clever technology, backups built into disk systems lots of work at block level and the demise of the tape drive  as we know it now. My only hope is that backup technologies such as NetBackup do manage to keep up with the storage technology, delivering a backup / recovery performance to match. By that stage I will have course have a beach bar in the Bahamas and will be slowly forgetting everything I ever learned about IT and backup 

- Thanks a lot Dhamicca!
