Has anyone out there experience this problem?<BR /><BR />Thanks<BR />Chris Tue, 23 May 2006 09:23:22 GMT https://community.hpe.com/t5/operating-system-hp-ux/fbackup-4003-failed/m-p/3793254#M265388 Chris Chaoman 2006-05-23T09:23:22Z https://community.hpe.com/t5/operating-system-hp-ux/fbackup-4003-failed/m-p/3793255#M265389 These could be one of the solutions for you:<BR /><BR />Run fbackup in single user state...this is the recommended method since problems with partially updated files (files open and changing during the backup) will be avoided.<BR />2.
