Got a server 2012 R2, shadow protect installed for backup . backups going to nas drive. backing up the whole server.
server has few drives. like ",c,d,e,f,g" . all drive successfully backing up. but "d" alone fails few times in a week.
not sure why it is failing. i went through shadow protect, found its failing with "503 fatal i/o error"
i just attached a screenshot for more info.
could anyone help with this issue.
