This is a follow up to an archived thread about “unarchiving” a backup of the data from a Time Capsule.
I have just started working with my second TC dual band and I have several Macs including a MacBook Air – which takes 17 hours to do the initial back up. The Time capsule is NOT a server. When you try to mount the drives on your Mac and copy files from one TC drive to the other the files are actually brought to your Mac via your network and then written back. (I have also not figured out how to connect two TCs together – you can connect them between one WAN to the other’s Ethernet port but cannot access the drives. Also server software knows you are copying to drives connected to the server so it handles the data directly between the drives.)
So I finally discovered the “Archive” function on the AirPort – which will archive an entire TC drive to a drive on the TC’s USB port. It’s reasonably fast. Next I moved and connected the USB drive the new TC but again we are back to copying to the Mac and back again. For example it said it would take 35 hours to copy 150 GB of data from the USB drive hanging off the back of the TC.
Reading the response to the thread above – which was not helpful to the poster – it dawned on me. Connect the USB drive to a spare Mac and copy the files back to the new TC – which would take half the time. Currently I am copying my 80GB backup of the Air to the new TC and it says it will take 6 hours. (The backups on the TC are sparse disk images so they are actually hundreds of little files in a package so will take much less than that but the Finder cannot really estimate the time.)
What we need is an ability to “restore” and archive with Airport Utility.
