We only use Dell EMC products.

I have very good exposure using Dell Avamar, Data Domain (DD), PowerVault, and PowerProtect Data Manager.

We are mostly also working with Dell. 

We use other products, but it's not a one-to-one comparison with Data Domain because they're software solutions. For example, competitors like Veeam Backup have only one software solution that you can't license to other users. You have to buy the license for Veeam Backup for a socket, but it involves all the the functionalities. Maybe you have to buy a part of the instances for taking the backup for the databases. 

We do deal with various other solutions. There are five others on the market. One is ExaGrid. IBM has another. 

If somebody writes an RFQ, like a government agency, that says, "You guys have to tell me what's best," all those companies will be competing against each other.

I'm not sure if we used a different solution previously.

We've used a variety of different products. We use different brands simultaneously. It depends on the customer's needs. Some offer more competitive tenders, and some are used based on the government structure.

EMC is a solution we are starting to move away from because of the cost more than anything. We are evaluating it along-side a Veritas product currently.

Previously, I did not use another solution. I am only familiar with Data Domain.

I did not work with other solutions prior to using Dell EMC PowerProtect DD (Data Domain).

We began working with this solution before the migration between Dell and EMC.

I have some experience with Veritas, and they offer backup appliances as well. However, they have nothing that can be compared to or compete with Data Domain. This solution from Dell EMC is the number one backup appliance.

Banks will often have Lenovo or IBM. I always prefer, and my company always prefers, Data Domain. It's scalable and robust and far superior.

We've used Avamar as a backup software. However, we find Networker has more features.

I have not used other solutions prior to Dell PowerProtect DD.

Previously, we tried deploying Tivoli Storage Manager. Tivoli was very complex. The backup and the restore procedures were complex, and the backup process took a very long time. 

There was an eighty percent improvement with EMC Data Domain.

We used IBM ProtecTIER. We move to EMC Data Domain for better performance.

We previously used HP Data Protector. The HP Data Protector backup was not secure. We used to do a backup, but at the time of restoration, it would give us some issues on the restored data.  We were not able to access and stream data on HP. EMC is much easier in terms of restoring the backup properly. 

Before using Data Domain, I was using a tape library. It was IBM Tape Library with LTO (Linear Tape-Open). We switched to EMC Data Domain because of the speed. Backing up data to a tape library is much, much slower than backup to Data Domain, which is based on hard disks. it's much faster in backup.

The system we switched to is actually EMC Data Domain as the hardware device for backup, while Veritas is the software backup. Veritas has its own hardware device. However, EMC Data Domain hardware is much better than Veritas. The golden combination as I see it is EMC Data Domain hardware with Veritas software. Going that way, I get the best of each in our backup solution.

Previously, we deployed Commvault HyperScale and the Veritas NetBackup Appliance, but the performance is better with Dell EMC PowerProtect DD.

Tape based backups

We were using HPE StoreOnce about four years ago.

I have seen other software based and hardware based De-duplication storage products, so far none has lived up to the efficiency, scalability and integrity of Data Domain.

No, we had regular backups to tape and a staging area, but no deduplication.

Before we used EMC VTL, an awful and nasty product from EMC with lots of manual work.

I used Sympana commvault and CA Arcserve. Both the products are good for small organisations but not up to the mark for enterprise level.

No, it was the first VTL we used for customers and because of its function and uptime we can’t see a reason to change to another vendor.
