Hi David, Hi Ronni, I think what David is looking for (correct me if I'm wrong) is redundancy for his Time Machine backup.
With drives so cheap nowadays, It is certainly something I have wondered about. Like many others, I already have the dual approach of: * a SuperDuper bootable clone - primarily in case of hard drive failure gets me back up and running ASAP * Time machine - in case of file problems, eg file corruption (already saved me here) mistaken deletion, etc But given the particular advantages of TM in certain situations (which the clone does not cover), it would be nice to have redundancy for the TM ideally a simple set-up that just effectively does the TM backup to two disks simultaneously. I would imagine one could always use a mirrored RAID drive but this introduces its own risks. It would just be nice to have some way to either have: 1. Time machine write it¹s backup identically and simultaneously to two attached drives (my ideal solution but I can think of no way to do it!) OR 2. Have an automated set-up to keep a second drive synchronised with the main TM drive. The purpose, of course, is to still have a fully functioning TM backup even if your TM drive fails. As you point out, the problem with your archiving solution is that you copy the entire drive contents a huge time-consuming task on a multi-GB drive whereas the beauty of the TM backup is it only copies the CHANGES typically a quick write of many small files. I wonder how a SuperDuper smartupdate would work this is supposed to only copy the files which have changed since the last update. I don¹t really know enough about how time machine works at that level to know if it would just recognise the clone without problem (if the primary TM drive had failed). If the solution DID work OK, I think you would need to be very careful with timing you would not want to be trying to do a smartupdate from your TM drive at the same time as a TM backup was happening. Anyway, David, if I misunderstood your post apologies for hijacking the thread ;o) Ronni, given your knowledge of the intricacies of TM, I would love to hear your thoughts. Cheers Neil -- Neil R.
