Time Machine Unmounts in System Restart

After a restart (all power remains on to all hardware) the Time Machine Icon has vanished from the desktop, and from the Finder Devises list. Powering down the TM external disk, and then on again, brings it all back. The disk is connected via USB. This, near as I can remember, is new to Snowie.
Bug or New "Feature"?
A full shutdown then power on (of all hardware) does not lose the TM disk.

Chuckle...I'm a wizard!
OK,OK, that is a stretch.
I have been posting (and reading posts) on these forums for years (see the little blue bars). If a program is acting peculiar, one of my own first steps is to trash the preference file. Preference files may become corrupted (rare, but it happens) and then all sorts of odd behavior can result. OS X rebuilds preference files as needed with default values. When you trash one and then restart, that is what occurs.

Time Machine causing slow system

I have been experiencing a problem since starting Time Machine. The system becomes very slow to come out of sleep mode (20-30 seconds). Every application becomes slow, but the slowest of these seems are the applications that have anything to do with the drives (mounting DVD, system preferences, Time Machine, Activity Monitor, Disk Utility, Finder).
I have tried connecting the external drive (Maxtor OneTouch 4 Plus 500GB) via both Firewire 400 and USB, but neither connection method solves the problem. I have used Disk Utility to verify both drives, repair both drives and repair permissions of both drives, but nothing has helped.
The slow response can be corrected by restarting the system, but the problem comes back and gets progressively worse the longer that the Time Machine is allowed to run.
Any ideas would be greatly appreciated.

Let it run, is what I have to say. Time Machine works well with some external hard drives, and poorly with others. I suggest either getting a new external hard drive (which I personally am too cheap to do), or just do time machine back ups at night when I'm asleep. It would save the frustration of slow back up time and still get the job done. Also, you might want to check your time machine preferences. There could be some settings that you could change to help out.

Hi, what Format is the external Drive?
They usually come PC Formatted for Fat32/MSdos, or NTFS... is there anything on it now?

Time Machine doesnt restore system exactly

Looking around, Apple claims TM restores the system to exactly how it was before the restore - so at least that's what I'm trying to aim for.
-I had the a harddrive clicking noise last night and luckily I had backed up hours before the clicking noise began. As soon as I restart, I could no longer boot up the OS as the clicking would begin as soon as the MBP turned on. Bummer.
-I popped in a laptop hd I had lying around while waiting for the RMA replacement on the dead one, and did a remote restore in Snow Leopard Dvd utility using my latest TM backup (used mount_afp afp://user:pw@host/ etc etc etc in terminal).
-I also looked over at the User Tips post by Glenn Carter on Restoring Your Entire System / Time Machine.
Now that I mentioned that, my photos are intact and my files I guess, but what irks me is that my system isn't restored "exactly" the way it was before the hd failure. My wallpaper is the default. My screensaver is the default. My dock is the default. The apps that run in my Menubar are gone. My widgets are defaulted. And my settings in PathFinder, Transmit, Curio, Steam, etc are all gone. They've also defaulted. Very annoying to configure every app installed. Simply put, my system as it is now after the restore looks exactly like a fresh install of SL and "not exactly" as my desktop-before-hd-failure which is what Apple suggests TM can do.
Am I doing something wrong? Any further tips? Should I restore again?

Did you do a full system restore, per #14 in Time Machine - Frequently Asked Questions (or use the link in *User Tips* at the top of this forum)?
If so, everything should have been restored, just like they say, unless things were excluded from Time Machine (there's some very bad advice about that on the internet).
All the things you describe are in +*<home folder>/Library/Preferences.+* If you used +Migration Assistant+ instead, you may have an extra user account, that has the restored preferences.
-I also looked over at the User Tips post by Glenn Carter on Restoring Your Entire System / Time Machine.
That applies to Leopard only.

I'm installing a new hard drive and wanted to restore it from Time Machine. When I restart w/ "command" /"R" it returns to orig. startup disk.

I'm trying to load a new harddrive using timemachine when I restart the Macpro using "command"/ "R" keys it restarts to orig. startup disk and not to restore option.

If you installed a brand new hard disk, there is no recovery partition. OS X Internet Recovery should enable you to boot with ⌘ R but this does not work on all Macs, just ones with updated firmware that enables this function. Yours may predate that ability.
Read this: from http://support.apple.com/kb/HT4718
Some computers that did not ship with OS X Lion or OS X Mountain Lion installed may have a software update available that allows them to use Lion Internet Recovery.
Therefore, without a recovery partition, your 2008 MBP cannot boot OS X Internet Recovery.
Boot from your original system installation disc, then restore from your Time Machine backup. It will create the recovery partition on your new HD.
Time Machine backup volumes are also bootable, so you should be able to boot from the TM volume using Startup Manager. Connect the TM volume then an Option key while starting the MBP.

Time machine restore crashed system preferences

Hi, just hoping someone can help with the following as my MacBook is not a happy bunny. I recently reformatted my hdd and restored my system using Time machine. This was to allow me to create a new partition so I could run bootcamp. All was fine for a few weeks, buy I have noticed recently that system preferences has become unreliable and fails to load on most occasions, freezing in the process - it shows in the dock, but does not load. I have OSX snow leopard all updates, two user accounts, guest activated. I have repaired disk permissions a number of times - sometimes works for a very limited time, other times not. I have deleted the finder and systempreferences .plist files in both user accounts, emptied trash and restarted, again limited effectiveness. When the sys prefs crashes, i force quit it, then it tends to load fine next time, but 2 mins later its up to its old tricks. On top of this, the Mac is now refusing to shut down - it will get to the spinning wheel phase then nothing, I have to force shutdown by holding the power button.
I've also tried disabling the guest account, but no luck.
Any ideas gratefully received as I'm worried that jts all going crash soon !
Many thanks
Rich.

Time machine recovery if system broken

Hi
I have time machine set up and it seems to be running great. For future reference, if I lose the whole system - or replace the system with a new one, and I able to simply load leopard from scratch, plug in the external drive and restore everything to where it was ?
Will time machine on the new system recognize that it has an old version on the external drive and provide an option to restore (hopefully it does not over write the old copy.
Appreciate anyone who has some experience of this

A qualified yes - to restore, you'd restart from the Leopard DVD. See also this thread:

Time Machine forcing computer to restart

I have just bought a new iMac and am trying to back up onto a external hard drive using time machine.
I have erased and partitioned the Hard Drive and then tried to back up onto it. When I do this it works until about 12gb of the 203gb are backed up and then a grey cast covers the screen with the message that the computer must be restarted. Before this started happening a few times a message just came up saying 'Unable to complete backup'
I am wondering if it may be a problem with my iMac hard drive because whenever I try to verify it this happens

Your disk directory for your internal hard drive needs to be repaired. Boot from your Leopard install DVD by holding down the "c" key on startup until you see the spinning gear. Choose a language and pick Disk from the Utilities menu at the top of the screen. Select your internal drive in the left window and click on Repair and repeat until no errors are reported. Then repair permissions.
Check your hard drive to make sure that there is fifteen to twenty percent of the disk space that is free. Mac OS X needs that much free space to operate properly and a too full disk is one of the things that can cause disk directory errors.

Time Machine and file system errors?

Hardware:
- 15" MBP 2GHz (mid 2006) 10.5
- WD MyBook Premium 320gb
Problem:
Time Machine backs up to a partition on the MyBook (drive is GUID partition table, partition is Mac OS Extended). Immediately after a TM backup to a reformatted partition, Disk Utility may or may not detect invalid sibling links, invalid key lengths, or other errors. If it does not detect them after the initial backup, subsequent backups of recently changed files will cause said errors. This is consistent; its occurrence is not a "maybe".
Disk Utility cannot fix these errors. fsck_hfs has had success in fixing these errors once. As I type fsck_hfs is running a second time, so we'll see the results from that. The first run produced the following:
fsck_hfs -ypr /dev/disk1s2
*Invalid node structure*
(4, 44282)
*Invalid volume file count*
(It should be 832071 instead of 802858)
*Invalid volume directory count*
(It should be 181916 instead of 177095)
*Invalid volume free block count*
(It should be 13931374 instead of 14042565)
*Volume Header needs minor repair*
(2, 0)
Questions:
- Of what is this behavior indicative?
- Is the MyBook necessarily bad?
- Is TM somehow the cause?
- Could bad sectors on the MyBook be the cause?
- Is the drive within the MBP the source of these problems (Disk Utility has not previously found any errors...)?
I'm really at a loss...

Boot from the OS X installer disc that came with the computer. After the chime press and hold down the "D" key until the diagnostic screen appears.
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.

Time machine unreliable - freezes System Preferences. Any ideas?

Backing up works properly for a little while and then seems to stick on Preparing. Won't obey Stop and freezes system preferences. I usually have to do a hard shut down. Used with Iomega which is a replacement for original that failed.

Time Machine causing my system drive to fill up

I really don't know what's happening!
I turned on Time Machine agian after having it off for a month or so. It ran a new back up (whch took almost 12 hours) and all seemed normal. But now, whenever it runs an hourly back up, my system drive gets filled up with something - I don't know what - until it has zero space left!
I can't tell what it's doing or what files have been stuck onto my system drive. If I could tell that, I'd remove them.
So I have two qusetions:
First, what is happening with my system drive? The only thing I've changed is turning on Time Machine. Why would it transfer files to my system drive instead of (or in addition to) storing backups on my backup drive? (The BU drive is a Western Digital 2TB)
Second, is there any way I can determine what files have been added to my system drive to make it fill all the way up? Is there some way to search by a criteria of "files saved to system drive in the last day"?
Please help, it's making my computer useless!

Oh boy Joe, what Apple doesn't tell you is that 10 GB of free disk space is not enough AND isn't free for your use, and in my experience 10.5.8 will be sluggish with less than 30 GB free, higher OS versions needing even more.
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
In the Memory tab, are there a lot of Pageouts?
See if you can clear off a few GBs.
How much free space is on the HD, where has all the space gone?
OmniDiskSweeper is likely the easiest/best, and is now free...

Time machine backup causes system to crash

Hi, I had updates coming through on my macbook, and didn't realise until the next day that the power socket wasn't connected to my mac. When I tried to use my mac I kept getting an error, in that the computer wouldn't run at all, wouldn't start up.
I tried to use a backup from my time machine but I wasn't able to do so and retain all my information on iphoto mail etc.
When I try and reinstall from time machine I still get the same problem.
Is there any fix that I can do that will allow me to access these backups and run them?
Many thanks

I've been having problems over the last few days. It seems that it's stuck on 'Preparing Backup'. The menu bar icon shows activity all the time, but my last backup was over a day ago.
My system has been intermittently locking up as well. Sometimes it will unfreeze after a few minutes. Other times I'll have to power off using the power button. Not sure if this is related to Time Machine, but something's not right at the moment (maybe after the 10.5.4 update?)
