Netbackup DFSR backup very slow

BTW - we are asking all these different questions so that we can (hopefully) offer some solid advice at some point later in this thread (which may well probably be quite a long thread by the time we get there).

.

What does this show:

C:\> fsutil fsinfo ntfsinfo F:

.

Some more detail about the VM (i.e. the backup client) hosting the problem DFSR:

Number of vCPUs?

Amount of vRAM?

Are all of the VMDKs thin provisioned?  If you have a mix of thick and thin provisioning, please specify which of these:  C: E: F: G:   is thick or thin?

How many different DFSR namespace roots do you have on each of:  C: E: F: G: ?

i am still working on the VSS events i mentioned earlier:

Volume Shadow Copy Service error: Unexpected error calling routine OpenService (shSCManager, 'VSS', SERVICE_QUERY_STATUS). hr = 0x80070005, Access is denied.
.

Operation:
Initialize For Backup

    We seem to have had two different VSS events:

    Log Name: Application
Source: VSS
Date: 1/26/2017 11:06:20 AM
Event ID: 8193
Level: Error
Computer: Serv-DFS02.csclebanon.com
Description:
Volume Shadow Copy Service error: Unexpected error calling routine GetVolumeNameForVolumeMountPoint is now failing on the volume, winerror 0x00000001. . hr = 0x80070001, Incorrect function.

...and another, but you don't show the event ID or when this occured:
Volume Shadow Copy Service error: Unexpected error calling routine OpenService (shSCManager, 'VSS', SERVICE_QUERY_STATUS). hr = 0x80070005, Access is denied.

    .

    Can we check the client's buffer size:

    # bpgetconfig -h serv-dfs02 buffer_size

    .

    This physical server seems to have a fair amount of storage.

    .

    Are any of E: F: G: from SAN/NAS storage arrays, or are all of the volume drive letters actually local formatted from physical disk within the server chassis?

    .

    If the server has local disk only, and no SAN/NAS storage, then please can you explain how the 9 TB of disk space is carved?  How many spindles?  Any RAID parity groups?  What model of RAID card HBA?    (I ask because we need to check a few things).

    Hello,

    E & F are EMC storages. G is local disk of 900GBs RAID 5 (Total 4 tb)

    client buffer size

    C:\Program Files\Veritas\NetBackup\bin>bpgetconfig -h serv-dfs02 buffer_size
    Could not print the serv-dfs02 item.
    buffer_size = 128

    both events have the same ID different description.

    i thought the events are shown during backups but the first one is dated yesterday when no backup was running.
