Time Machine Backup Across Network to External Drive

[wiederkehr]

Our main machine is an iMac with an external drive (Drobo 5D). Currently the Drobo has two volumes -- one for TM backups of the iMac and another for everything else. I'm looking to perform wireless TM backups of two MacBooks to the same Drobo. On the MacBooks, using Finder, I'm able to see the Drobo TM volume but unable to see it through Time Machine.

Is this possible? Any suggestions on how to proceed?

Thanks

Is the Drobo connected directly to the iMac? If so, this would be why the other MacBooks can't see the drive for TM but can in the finder because that volume is linked to the iMac.

You would need to share the storage over the network.
