I was using BRU with a tape drive, but it died. Now we want to use drobo to backup 8 macs and 1 server instead of tape. We will swap out drobo monthly for offsite. Is there a simple disk to disk backup solution that also works over the network on the mac side. BRU and Retrospect have you create librarys and staging disks which are impractical for the backup administrator. Any suggestions welcome.
