I have single on-prem Exchange 2019 installed on win2k22 with 5 mailbox databases.
We’re using netbackup version 10 server to backup databases/logs and client 9 on OS
Since Monday evertything correctly, now during exchange full backup or differential incremental we’re getting error on the master server ,
Nov 14, 2024 1:30:05 PM – begin writing
Nov 14, 2024 1:30:22 PM – Error bpbrm (pid=1546320) from client exchange01: ERR – Terminating backup.

On the exchange client side (in the bpfis file) we’re getting status as below right before an error shows in the master server (activity monitor -> jobs )

In the bpbkar file we see other error

I checked vss writers status on the exchange and all of them are stable and no errors, application logs for any errors , permissions for netbackup client , network and storage system in terms of issues and stability, antivirus but still not luck.
Can you please point out what should be checked and investigated ?
