Hi,Is anyone using the HotAdd transport method for backing up VMware virtual machines?I tried it for a few days and achieved about 10x faster backups than with NBD. But then we had an issue that for one VM the virtual SCSI devices mapped on the media...

The NetBackup 10.1 admin guide [1] says about the "Exclude deleted blocks" VMware optimizations:Reduces the size of the backup image by excluding any unused or deleted blocks within the file system on the virtual machine. This option supports the fol...

Hi,Is there a limit on maximum VMware virtual machine disk or VM size when backing it up with Veritas Netbackup 10.1 for VMware using HotAdd method? For some VM's (1 TB size or more) we're having issues when NetBackup creates a VM snapshot, does back...

Hello,We are using VMware vSphere 7 running on Cisco UCS blade system. VMDK data storage is NFS on a Netapp AFF A400 storage system. NetBackup 10.1 media server is running on RHEL8 in a VM and has BasicDisk NFS mounted volumes from a Netapp FAS 2720 ...

Hi,Is it possible to rename BasicDisk storage units? They have the media server hostname in the name and I would like to mount them with NFS from another media server. I haven't found a reference for it. Not in the docs, not in Java or Web UI or comm...

Thanks for your reply. The backup media server is a RHEL 8 VM with SCSI controller type "VMware Paravirtual".The backup client that caused issue indeed has SCSI controller "LSI Logic SAS". Unfortunately all the Windows VMs use "LSI Logic SAS" by defa...

Thanks. We don't have a SAN, only Netapp AFF A400 (VMDK disks on NFS) and Netapp FAS 2720 for the BasicDisk mounted via NFS on the media server VM.Transport over NBD is quite slow. Bottleneck is not the storage or the network. I tried once with Hotad...

Any ideas how NBD speed can be improved? Netapp NFS storage and network is not the bottleneck and also not CPU/memory of the media server VM.I looked at Replication Director that it can backup VMs using Netapp Snapshots/SnapMirror, but I could not se...

Any ideas if that is even possible for XFS or it will come in a future release?
