ALL_LOCAL_DRIVES and Cross Mount Points

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.
