Time Machine: Airport/USB drive or File Server? - space-time - 03-26-2015
I have some older Macs backing up with time machine to a USB hard drive attached to an Airport Extreme Base Station. I have some newer Macs backing up to a Mac Mini File Server.
One difference I see that that via Airport/USB, they back up to a disk image, and when using the server, they back up to files and folder (no disk image involved).
Moving forward, I need to make some upgrades. Is there a good reason to choose one of the other? which method is more reliable?

Just curious... is the Mac Mini running OSX Server?
On my OSX Server, running a Time Machine backup destination, I get the disk images from all of my workstations.

Yes, 10.6.8 server but I think it backs up to files and folders, I don't think there is a disk image. I back up to an external drive attached to mini. I will check tomorrow to confirm that I have files and folders on that drive.
On the airport disk I do have disk images, one for each computer.
EDIT:
I just checked: the mini itself back up the the external hard drive to files and folders.
The MacBookPro backs up to the same external drive (via File Sharing) to a disk image. So I was wrong last night.

I created my own sparsedisk images and then copied them to the USB drive hanging off my 5th gen AirPort Extreme. I can still use it as a local file server if I want. For each Mac, Time Machine mounts the disk and then unmounts it when done, just like if everything was a Time Capsule.
And if I need to copy the backups to another drive, it's as easy as using the Finder to drag the sparsedisk image, something you can't do with a tethered ™ Backups.backupdb folder.
Actually, even if all I had was a tethered USB drive (not a network drive) I'd still setup TM that way for those reasons ... also means other users don't accidentally futz with an always-mounted TM drive.

The instructions above work for anything 10.6 or later, but for me didn't become rock solid until 10.7 or 10.8 ... it's not the "unsupported" router that was the issue.
