SQL Server 2012 always-on backup, full vs copy-only I need a quick clarification on copy-only backup vs full backup as it pertains to transaction log numbering and restore if required.

I have SQL Server 2012 setup with always on for multiple databases. The availability groups are setup with preferred backup on replica.

only copy-only and transaction log backups are possible on replica. Does this mean I will need to do a full backup on primary if a restore of the transaction log is required? 

Thank you

NO -- You can add t-log backups to a restore of a COPY_ONLY backup
