Question on Vaulting inline backup copies

Ok so that is the reason it is not working.

My vault profile has "include all" for every criteria, except the volume pool, where I only include "Daily_Offsite

In the choose backup tab please make sure to include all for everything. Select all in 'source volume group' and 'volume pool' as well.

You have to specify the pool that you want to eject in the eject tab. In the eject tab select daily_offsite pool.

for example, if set the volume pool to 'Daily_Offsite' and this  is not the primary copy, it won't eject.

There is document on this but I don't have that handy, will update once I have it.

By default , vault will choose the primary copy.

If you want to use a different and non-primary copy, check out this technote: http://www.symantec.com/docs/TECH74265
