NetBackup + Hyper-V Cluster
i'm facing some trouble backuping Hyper-v machines on CSV cluster with NetBackup 188.8.131.52.
I have an Hyper-V cluster with 4 nodes. When i look into Failover cluster manager ==> Cluster Shared Volumes i can see VM on state "Redirected Access"
or "Backup in progress, redirected access" even if no backups are running...
When a backup starts on this cluster jobs can stay on "Begin Snapshot" status for weeks if we don't cancel it. Several bpfis process can be seen on the Hyper-v host.
When i look into DOS command ==> DISKSHADOW> list shadows all i can see 7 old shadow copies from August 2012. It seems that some old backups failed and snapshots
weren't deleted, so VM's stuck in "redirected access" mode.
Is it safe to delete those old shadow copies and retry a backup ?
Thanks in advance
