Hello Experts,
We have cross mount points enabled with All_Local_Drives selected in backup selection in Standard policy.
I checked its not recommended.
"Do not select Cross mount points for policies where you use the ALL_LOCAL_DRIVES directive"
Could you please explain why is it so? Why we should not include both.
I want my whole unix machine backed up.
Thanks,

Hi,
It could backup a file system twice. From the note https://www.veritas.com/support/en_US/article.000044241
"Do not use Cross mount points in policies on UNIX systems where you use the ALL_LOCAL_DRIVES directive in the backup selection list.
Enabling Cross mount points can cause multiple backups of mounted volumes."
Basically, if you use ALL_LOCAL_DRIVES netbackup will generate a new stream for each file system (/,/usr,/tmp,etc). If you've enabled Cross mount points then while the netbackup is busy backing up /, it will find /usr and reason that Cross mount points is enabled so it should cross the boundary and back /usr up too. Meanwhile there is a separate stream for /usr so it will be backed up twice.
Use ALL_LOCAL_DRIVES if you want the entire system.

Just as a reference, its REQUIRED for Windows policies to have ALL_LOCAL_DRIVES and "Cross Mount Points" selected, else mounted folders won't be protected.
