SharePoint backup job failed, status 71.
Just to share my issue and the solution.
I had a SharePoint farm with 2 servers : one for IIS, second for SQL. I configured my SharePoint Backup under NBU 188.8.131.52 as requested in Netbackup For SharePoint Admin Guide.
I launched my backup, 3 jobs were created : parent, SQL data (on SQL Server), dans Global Settings and Search (on IIS server). SQL job finished with status code 0, IIS jobs finished with satus 71.
I searched a lot in docs, forum, without answers... and... I found this TECH195147 about code 1 under SharePoint. I thought that it was not same problem but it was... For the same issue, you have code 1 if your SharePoint server is SQL and IIS, and if you have 2 different servers, IIS job will return status code 71.
So, I have created this post for people who search "sharepoint 71" :)
PS : Sorry for my english :-/
