Hi Matt, Thanks for your response and for offering to help.
I am still having this problem, and I will try to provide the details you requested. Both systems are wired (connected directly to my router). You asked how I am sharing things for Time Machine. I am not running OSX Server. I have both computers set up to share files (i.e., the File Sharing option in the Sharing module of the Preferences app). The remote Time Machine computer shows up in the Shared section in the left column of the Finder on the main computer. I click on that entry, which connects to the backup computer. I click on the Time Machine disk, which I guess mounts that remote disk on my main computer. Then I go into the Time Machine module of the Preferences app on my main computer and click on the Select Disk button. The Time Machine disk on the remote computer shows up in the list and I select it. That remote disk is identified as being on the backup computer. It shows the correct amount of total space and remaining space, but it also says "None" for both the Oldest backup and the Latest backup. If I go to the backup computer and click on the Time Machine disk in the Finder, I see 2 entries. I assume these are for the 2 computers. One is a folder called Backups.backupdb, which I assume is for the local backups on the Time Machine computer. Within that folder is a single folder with the name of the backup computer, and that folder contains a bunch of folders with names that look like dates plus other ID numbers. The second of the 2 entries on the Time Machine disk is a Sparse Disk Image Bundle with the name of the main computer (i.e., the one I want to backup). If I right click on that bundle and Show Package Contents, there are 8 entries. There is a folder called bands and 7 files with the following names: com.apple.TimeMachine.MachineID.bckup com.apple.TimeMachine.MachineID.plist com.apple.TimeMachine.Results.plist com.apple.TimeMachine.SnapshotHistory.plist Info.bckup Info.plist token The bands folder has 270,565 files in it, with names that are a mix of letters and numbers (but they do not look like dates, as in the other backup folder). I have not tried removing the cable modem while doing this. What happens when someone wants to upgrade to a new Time Machine disk? Isn't there a way to set up a new disk, copy the old Time Machine backups to the new disk, and then have Time Machine do incremental backups from there? If so, is there some way to use that same methodology in my current situation?
