Prachia,
What you mean by "VMDK for Backup"? Are you pointing to VMware build in VM Backup
Veritas NetBackup is certified for VMware Virtual machine backup and it's giving you the flexible options for Backup and Restore.
"One single path backup-two level restore(Image level and file level)" and as well as Incremental backup for VM
No need to install/licence veritas for individual VM
BTW,here are the challenges that we face.
1. We were unable to run multiple copies parallel copies of VM backup
Remedy: We implemented inline backup
2. Some of the snapshot deletions failed with some VM ware errors
Remedy: solved by scheduling VCB script to delete the missed out snapshots
3. We were unable to run backup for VM that do not have NIC Card(We got a project they require machines without network card)
Remedy: Implemented display name based backup
4. We were Unable to do automatic VM restore converstion (restore all virtual machine files to virtual machine server automatically using VMware
converter)
Remedy: Downgrade to VMware convertor 3.0.2
