@Karthik_C i compared and BAckup exec for virtualization is twice cheaper than Veam.Maybe Veeam is faster, but Backup Exec is very realiable and trusted.
Backup Exec 2020 -backup job:
- virtual machines: 4GB/min;
- MS SQL: 8GB/min;
- duplicate to tape (LTO 8)- 8-10GB/min.
The time depends on the speed of the storage source/destination.
- For Veritas Backup Exec: Licenses are per client that you want to backup and depends on if it's only an agent for the system or for an application.
- For VMware, the license is per VMware host.-
I don't have experience with IBM Spectrum Protect, but I do have experience with Data Domain.
I would recommend it. It's very stable, has high performance, and the highest deduplication engine.
