Backup plans and Primary Copy to Tape

I have an implementation where the customer is writing backup jobs directly to tape.
They are LTO-9 so have 18TB in capacity.

Total Full backups are 6TB.
 

I have created multiple plans for VM’s and SQL backups. They run at different times and have different retentions for daily backups.

What I’ve noticed is that each Plan (Storage Policy) writes to its own tape which is far from ideal for tape usage. 

 

The only thing I could think of is to not use plans, create 2 Storage Policies (to satisfy the different retentions) and then create schedules in the Commvault Java Console as we did many years ago.
Is this still the best method?

Thanks in advance.

Mauro

Storage Policies were married to tapes the same way that Plans.  The only way to write muliple Storage Policies to a tape is to use a global secondary copy.

Would this be the case if my Primary job is writing to tape? I would like all Primary copies from the various storage policies to write to the same tape.

Hello ​@Mauro ,

If you select ‘Primary Copy to Tape’ during Policy Creation, the pool will be displayed, but the tape library will be used in the same way as a standard library without the pool function. So this copy will use its own tapes.

An other issue; If you have a storage policy that uses a disk for the primary copy, and you then add a secondary copy to a global secondary copy or tape pool, you cannot upgrade this “tape pool copy” to a primary copy either. That might be why it’s called Global Secondary Copy.

This restriction has been in place for some time. Perhaps Valter could explain the background to it.
