Hi,
We get intermittent 156 errors on windows backups relating to open files and the Volume Shadow Copy service. I've read this doc about it - https://support.symantec.com/en_US/article.TECH38709.html - but have a few questions.
I understand that Netbackup with VSS attempts to make a temporary point-in-time backup copy of an open file and then backs that up. Does it do this with all open files? What if I had a 100gb SQL database mdf file that was open, would VSS attempt to make a temp copy of it?
If I turn off open file backups for a Windows server does that mean I get no backups of open files, including all the key exe files that the windows system and applications run? It sounds like a backup with open file backups turned off would be fairly useless if used to restore a server - is that a fair assessment?
Thanks
