Hello Glenn - I apologize - here are some answers:
First, how do you know the TC is full? I open TM preferences and it says that there is only 30MB of memory left out of 460GB.
Are you storing other files/folders on there besides your Time Machine backups? That is highly unusual that it would get that low without Time Machine beginning to delete old backups. If you are storing other files I would suggest attaching a USB hard disk to the USB port of the TC and using that for other files/folders. Leave the TC for Time Machine backups only.
If you are getting an error message, what exactly does it say? No error - the icon with the little arrow circling the clock indicates that there is a backup preparing, but it never follows through and I do not get an error message. It is supposed to warn me when it deletes onld backups, but I have never received it. I am thinking that I need to find the TC preferences instead of the TM prefs?
The only place to configure the TC is in the Airport Utility. If you have the setting checked in the Time Machine Prefs, it would tell you when old weekly backups are being deleted. I have never seen Time Machine backups get so large as to only leave 30MB left without starting to delete old weekly backups. Something is wrong.
How many Macs are backing up to the TC? Just my iMac backing up to TC.
How do you know the iMac has not been backed up in a month? If I go into TM the last available backup is from late March 2009.
Try initiating a backup by going up to the Time Machine menu and selecting "Back Up Now".
What happens? If it fails, what exactly does the error message say? Like I said, it says that it is backing up...I will try to stop the backup and then start another though hold on...Okay it looks like it is just going to do what it always seems to do - prepare backup for a while and inconspicuously stop with no error message, but I will wait for a half hour and see before I post this...Yeah - it is still preparing after a half hour! I think there must be something wrong...
Well, with no space left, nothing is going to happen. Time Machine needs room to move files around. Without that room Time Machine is trapped.
You have a couple of options. You can launch the Time Machine browser and free up some space. How far back do your backups go? What is the date of the earliest backup when you enter the Time Machine Browser?
*Recovering Backup Space*
If you have discovered that large unwanted files have been backed up, you can use the Time Machine “time travel” interface to recovered some of that space. Do
NOT, however, delete files from a Time Machine backup disk by manually mounting the disk and dragging files to the trash. You can damage or destroy your original backups by this means.
Additionally, deleting files you no longer wish to keep on your Mac does not immediately remove such files from Time Machine backups. Once data has been removed from your Macs' hard disk it will remain in backups for some time until Time Machine determines that it has "expired". That's one of its’ benefits - it retains data you may have unintentionally deleted. But eventually that data is expunged. If, however, you need to remove backed up files immediately, do this:
Launch Time Machine from the Dock icon.
Initially, you are presented with a window labeled “Today (Now)”. This window represents the state of your Mac as it exists now. +DO NOT+ delete or make changes to files while you see “Today (Now)” at the bottom of the screen. Otherwise, you will be deleting files that exist "today" - not yesterday or last week.
Click on the window just behind “Today (Now)”. This represents the last successful backup and should display the date and time of this backup at the bottom of the screen.
Now, navigate to where the unwanted file resides. If it has been some time since you deleted the file from your Mac, you may need to go farther back in time to see the unwanted file. In that case, use the time scale on the right to choose a date
prior to when you actually deleted the file from your Mac.
Highlight the file and click the Actions menu (Gear icon) from the toolbar.
Select “Delete all backups of <this file>”.
Alternatively, scroll all the way back to the earliest backup.
Highlight an item in the Finder window and click the Actions menu (Gear icon) from the toolbar.
Select “Delete backup".
This will delete only the files/folders that were backed up on this day or week.
Now exit the Time Machine Browser and see if Time Machine can proceed with a backup. If not we have something else we can try later. Cheers!
