We evaluated local tape drives. We were using the tape drives from IBM (LTO 3) before the Dell EMC equipment and the product was good but not reliable. 

The backups available on the tape drives have no reliability whether you store them correctly or not. They depend on the nature of the tape or the condition of the tape.

When comparing Dell PowerProtect DD (Data Domain) to its main competitors, such as HPE StoreOnce, it is important to note that the internal features, like deduplication and compression algorithms, are significantly different. Also, the deduplication ratio in Dell PowerProtect DD (Data Domain) is more reliable when compared with other vendors like StoreOnce or any other disk-based devices.

When we help our customers or some governmental structures to prepare the documents for bidding for some tenders, we investigate the details and competitive features of our solutions. That includes Dell EMC, HPE, and Quantum Alliance. They are all very close in functionality.

HP tends to have higher pricing; however, Quantum is quite close in terms of cost.

I've compared Data Domain to NetBackup Appliance. The pros for Data Domain are the starting capacity and the scalability, but the pro for the NetBackup Appliance is it's being integrated with their backup solution, which is NetBackup software. In terms of the integration with the software and the ability to have it, if you have a problem with your backup, you can restore it on the same machine. So, it's better in terms of NetBackup. 

Overall, whenever we integrate Data Domain with NetBackup software, it's been good.

We just want to learn the difference between the DPS solution in Azure and Azure's own backup solution. I'm trying to measure for my customer if the DPS solution has different features for a better backup from an Azure site's backup.

I can compare the instructions in the also Azure site as well. I have a lot of mechanical Data Domain on my site. Also, I have got Data Domains on the Azure site.

We tried IBM TSM and it didn't work. It was complex. Before IBM TSM it was a manual process, backup was done on external storage/ Tape and then transported daily from Production to DR Site. It was expensive, tedious and time consuming. In fact it was not a good experience moving the backup manually to the DR site.

IBM ProtecTIER and Oracle's Zero Data Loss.

At the time of purchase, there was no other solution that was able to perform the same tasks.

The company chose this product not me, so no.

Was not present in this decision.

For enterprise level backup solution – No .

No.
