Hello,

I am facing backup failure on client server, below are the details:

08/03/2018 01:00:55 - Critical bpbrm (pid=11992) from client swmnzbokwf: FTL - socket write failed 08/03/2018 01:01:12 - Info bpbkar32 (pid=16316) done. status: 24: socket write failed 08/03/2018 01:01:12 - end writing; write time: 1:09:06 08/03/2018 01:01:29 - Info bpbrm (pid=15748) Starting delete snapshot processing 08/03/2018 01:01:44 - Info bpfis (pid=16132) Backup started 08/03/2018 01:01:44 - Warning bpbrm (pid=15748) from client swmnzbokwf: cannot open C:\Program Files\Veritas\NetBackup\online_util\fi_cntl\bpfis.fim.swmnzbokwf_1533246689.1.0 08/03/2018 01:01:44 - Info bpfis (pid=16132) done. status: 4207 08/03/2018 01:01:44 - Info bpfis (pid=16132) done. status: 4207: Could not fetch snapshot metadata or state files socket write failed (24)

It would help to know what kind of backup you were doing - policy type and backup selections.

Putting the linebreaks back in, with my responses:

08/03/2018 01:00:55 - Critical bpbrm (pid=11992) from client swmnzbokwf: FTL - socket write failed
When you get this from bpbrm, look at the client logs. In this case, bpbkar.

08/03/2018 01:01:12 - Info bpbkar32 (pid=16316) done. status: 24: socket write failed
What socket? Look at the bpbkar log for information. If it was the socket to bptm, did bptm time out? Did it crash? Look at its log on the media server. If it was the socket to bpfis, did bpfis end unexpectedly? Look at the bpfis log.

08/03/2018 01:01:12 - end writing; write time: 1:09:06

This is a normal result if the prior bpfis process did not create the file. Bpfis processes on Windows come in pairs, "bpfis create" to manage a transaction with VSS and create the snapshot, the "bpfis delete" to communicate status to the first process and clean up. The file that wasn't found here is called the state file. When a snapshot is created, the state file contains the information necessary for later processes to use the snapshot.
