    As synthetics requires that the last synthetic full be available along with the inceremental or differential set, then I believe the merge for a new synthetic happens in memory on the media server before being written to the storage device.

    As such Synthetic and a cloud backup together is probably not a good idea as it will be moving a huge amount of data backwards and forwards across the network link to the cloud.

    If your cloud storage is dedup based then forget about Synthetic as Dedup should reduce the data being actually written across the link and Backup Exec 2012's restore view presents a "Synthetic view" of Fulls and Incs (or Full and Last Diff) and then requests any separate pieces of media as needed during a restore. Prior to 2012 you would have to restore from full first and the restore from subsequent diff or inc sets.

There is no good method TODAY to send backups to the cloud.  It's pure logistics and cost.  How do you send multiple TB's of data over a WAN link, in a reasonable amount of time?  

Your costs to store 60TB in the cloud will be very high, where tape costs will start to look reasonable...

Perhaps look to the cloud for archiving, or only for the most critical backup sets.  And not all of your data.  If you think all data as equal and all has to go to the cloud, youre doing it wrong.
