DFSR backup was change after update of netbackup

[nounejmak]

Hello,

backup of DFSR was backed up normally via current drive letter V:\

after reinstalling netbackup from 6.5.5 to 7.1.0.4, dfsr backup is running with shadow copy components

now backup takes too long, because backup of shadow is always full

how it can be changed back via drive letter?

[AmolB · Accepted solution]

DFS data has to be backed up through Shadow Copy Components of the server

Refer to the below forum thread

if i  will turn off dfsr for shadow?

it will be backed up via drive letter?

HKEY_LOCAL_MACHINE\SOFTWARE\Veritas\Symantec\BEDS\Engine\Shadow Copy Components

 Add a new registry key called "Additional Not Authorized Writers"

      Inside this new key, create a REG_SZ value named "DFSR" and give it the value "{2707761b-2324-473d-88eb-eb007a359533}"

I assume you have already read this technote. Make sure you need to stop "DFS Replication" Service while backup. Or, try UNC path backup from alternate client.
