Does Time Machine still work when logged out?

Potentially dumb question here... but will Time Machine continue backing up if I log out? I don't want my administrator user account always logged in, but I want to make sure our central files are constantly being backed up.

Hi,
I logged out of my server before going home last night. When I came in today, there are Time Machine updates throughout the night.
To check this yourself, just logout and then the next time you login, open your Time Machine volume and see if there are any updates. I think you'll find that there are.
Hope this helps!

If i move itune to external drive does time machine still have backup?

if i move itune to external drive does time machine still have backup?
I just moved my itunes off my macbook pro because it was taking up too much space and put it on an external hard drive. i have a second external hard drive that i use for time machine. when i update time machine next will my itunes files be removed from the backup since they are no longer on my internal hard drive (what time machine backs up?) basically, i want to make sure i have a second copy of my itunes besides the one on my first external hard drive and i was wondering if time machine will still have all of that data (on the second external hard drive).
i cant find this answer anywhere!!! thanks so much!!!

Check to see whether or not it's excluded in the Time Machine pane of System Preferences.
Items deleted from the hard drive won't be deleted from the backup until the backup location runs out of space.

Does Time Machine only work with external HDD's and Networks?

I have a Mac Mini that I just replaced the optical drive with a hard drive. This second HDD is formated into two partitions, with one of them being for my Time Machine backups, the other a media scratch drive.
When I try to choose this volume in setting up Time Machine, I get an error message that says, +"Are you sure you want to back up to the same disk your original data is on?"+ The message goes on to explain that +"the volume you have chosen for storing backups is on the same disk as the volume containing your data... you should back up to a volume on a different disk."+
The volume that I have selected IS on a different disk than my start-up system drive and the data to be backed up IS NOT on the same disk as the disk storing the backups. System Profiler defines my startup HDD as "BSD Name: disk0" and my second HDD as "disk1," with the two partitions "disk1s2" and "disk1s3." Mount Point for the start-up HDD is "/" and the two partitions on the second HDD are "/Volumes/Scratch Disk" and /Volumes/Time Machine." These two volumes show up as options when I "Choose Backup Disk" in Time Machine, but not the Mini's startup HDD.
Does Time Machine allow the use of second internal HDD? I have an external HDD, but it has a clone of my start-up drive on it. Thanks for any help.

Chris, excluding the other volume could certainly be the issue since the two options that I'm given for a backup volume are both on the same hard disk. The start-up system HDD is not listed. Maybe the message is referring to this, rather than to the start-up disk.
Not until after I selected "use this volume anyway," did I get to the "Option" screen to exclude items from the backup. When I selected "+" I was surprised to find the other volume, Scratch Disk, listed along with the start-up HDD as being included in the backup routine. So I selected Scratch Disk as one of the items to exclude.
As V.K. mentions, the cautionary message is rather vague as to what exactly it is referring to. Thanks.

Why does Time machine still ask for a disk when it is switched off?

My Time Capsule recently died, PSU problems , I think. So I went into system prefs and deselected the Time Capsule as the back-up disk in Time Machine and switched off Time Machine. Yet every few minutes I get a window appearing telling me Time Machine can't find a back-up disk. Why is this happening and how do I stop it? Thanks
Mac Pro 2 x 2.8 GHz Quad Core Intel Xeon, 6 Gb RAM, OS 10.8.2

Mountain Lion may expect to be using a local disk if external is not available..
Delete the plist.. this gives info.. whether it helps I don't know.

Why does Time Machine not work over wifi but only via ethernet cable ?

Hi everyone,
It's been some time I have this problem now.
The first time I backed up my mac within Time Capsule with time machine, I chose to use the ethernet cable because the gigabit connection is much faster than the wifi for the first back up, but now, any time I want to update this back up, I need to connect the cable, cause "Time Machine can not connect to the Drive I picked" over wifi.
This is so annoying. Does anyone have a similar issue ?
Any solution ?
When I got this "error" I can use Utility Airport and get full access to the drive, even in finder. The only thing that doesn't work is TimeMachine connecting to the drive, even if it is detected by TimeMachine itself.
Thanks.
Riccardo

Typical Yosemite.
I suggest a full reconfigure of the TC.
Follow this list..
No files are deleted on the TC doing this although you might have to repoint your laptop to the backup.
Note.. even if TM does connect it will say it is going to do a new backup.. it is only when it starts that it discovers the backup exists and increments it.
Start from a factory reset. No files are lost on the hard disk doing this.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 for basestation and and TCwifi wireless name.
If the issue is wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. ie plan on a first and second round of changes to fix this.. hopefully.. I will point out other steps that can be round2.
2. Use all passwords that also comply with 1. but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. If the TC is main router you can skip this point. This is only an issue when the TC is bridged.
Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only. Do the same for ethernet if you use it.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the computer itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.
Macbook can't find Time Capsule anymore
Start from the bottom and work up.. I have a list of good network practice changes but I have avoided Yosemites bug heaven.
Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.

Does Time Machine still do incremental backups after a restore?

Hi --
We have a 500GB external iomega drive that just died and I have been working to restore it's files from Time Machine onto a new 500 GB drive. I formatted the new drive and gave it the same name as the old one, and it looks like Time Machine was smart enough to do the right thing and restore the files to their original locations.
However, this morning -- within 24 hours of completing the restore -- we see an error message from TM saying it is out of space and it cannot perform a backup. It claims that about 450 GB are needed, which is about the same size of all the files we restored. Is it possible that once backup files are restored they are not longer considered backed up, and thus Time Machine immediately tries to back up all the files it just restored? I assumed it would still do incremental backups but recognize that restored files do not need to be backed up again unless / until they are edited...
Thanks,
Ram on

That's quite unusual. Normally it does a full backup immediately: http://support.apple.com/kb/TS1338

Why does Time Machine Hang OSX when a USB drive does not respond?

I use USB drives to store photo data. When I back up the drives using Time Machine to a Time Capsule, If I have added a large amount of data to the USB drive, the backup will consistently fail with the drive hung. I can see the drive in finder, but I cannot see the directory structure. Often OSX hangs too and I cannot even get to finder, just the whirling colored wheel. Sometimes the system has entered sleep mode and it will not wake up. I if I am using the monitor, I can open the MAC Book Pro cover and the screen there shows alternately, a blue screen and the screen wallpaper, flipping back and forth but otherwise unresponsive. If I turn the USB drive off the OS recovers and Time Machine completes, usually indicating a backup failure (but not always). The drive is always very hot under these circumstances, indicating that the system is issuing repetitive operations to the drive. I should emphasize that I am not writing to the USB drives during backup, Time Machine is just reading the drive. So several questions:
1) How in the world can a non system drive hang the Operating System? This is a big no-no for a supposedly multi-tasking Operating System.
2) I use Aperture 2.1 to store data on the USB drives with no problems (at least so far). Why would Time Machine drive the USB drive so hard that it fails? I had the same problem using a USB drive with iTunes. It completely fried the drive by writing to it too intensively during one of the frequent software updates. Is there no throttle mechanism in OSX that limits the disc activity so that the throttle mechanism is not the failure of the drive itself?
3) Does Apple have a list of USB drives that it has validated to be able to work with it's system reliably?

Are the USB drives powered from the computer or do they have their own power supplies.
There is a limit to how much power can be drawn from each USB port and also a total limit. If you exceed this, unexpected things can happen.

Does Time Machine ONLY work with Time Capsule?

Hiya-
I've got a La Cie big ethernet disk that I've been using for my back-ups and finally stumbled across time machine and thought it would work better than the La Cie back-up software, however Time Machine doesn't seem to want to know anything about any other mounted disks unless they're through an airport.
My ethernet disk is connected through a netgear router and mounts just fine on my pwr book.
I am doing something wrong or is this just a nifty system feature to coax folks into buying a time capsule (even if they're on a pc!).
Cheers in advance,
tripp

Hello Pondini,
I am able to back up fine with an external disk attached via USB directly to my MBP. This is a OS X formatted disk from WD. But TM does not back up if I connect the disk to my Airport Extreme (via USB).
It sounds from your comment that there is a way around this ... could you please explain how I should use the terminal command?
Be extremely careful when using Terminal. It is a direct interface into UNIX, the underpinning of OSX. There are few protections against making a mistake, which can cause untold damage.
Open the Terminal app (in your Applications/Utilities folder).
In Terminal, the prompt looks like this: user-xxxxxx:~ <your name>$
(where <your name> is your short user name). It's followed by a non-blinking block cursor (unless it's been changed via Terminal > Preferences).
Copy the following, exactly, after the prompt, then press Return:
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

Why does time machine not work?

First time machine was continually backing up, or not. Icon wouldn't respond. Started up on my Snow Leopard disk and it supposedly fixed the problem with disk utility. Now it will open time machine, but it doesn't work. I can't get a responce from the callender ot arrows. Then I have to command, option, esc to get out. Any help? It's 10.6.8.

Does Time Machine still ignore mounted disk images? Specifically, encrypted sparse bundle disk images?

My Time Machine backs up to Time Capsule which cannot be encrypted. I also have confidential data in an encrypted sparse bundle disk image in my home folder. When TM backs up and the encrypted sparse bundle disk image is mounted and I'm accessing the data, does TM back up the data "in the clear" decrypted form or does it exclude the disk image because it's mounted? I've done a little research, but there's conflicting information. Not sure what happens in Lion now...

Time Machine does not backup mounted disk images! The encrypted sparse bundle disk image was mounted, I updated a doc and did a TM backup - the file was not listed in the TM repository and the doc remained unchanged in the encrypted sparse bundle disk image on TM. Then I ejected the disk image and did a TM backup - the updated doc was backed up in the encrypted sparse bundle disk image! Thank you!

HT3275 Why does Time Machine backup fail when an external drive is included in backup?

Time Machine will not perform a backup when I have an external drive (formatted Mac OS Extended - Journaled) included in the backup. My understanding is that it should. What am I doing wrong?
Thanks.

"The backup was not performed because an error occurred while copying files to the backup disk."
Ah, not one of Apple's more informative messages.
There's a problem with a file on that disk. See #C3 in Time Machine - Troubleshooting. It will show you how to locate the message(s) that describe the problem, then help you fix it.

Why does time machine back up when no new files have been added?

I run time machine manually and even after having just back up, it says it is backing up 50mb of something. Nothing has been added or taken away. It just keeps adding and using up disk space.

System files are constantly changing, TM backs the whole machine up not just the files you are working on,
And 55mb is small change

OS X 10.5.3 update... Does Time Machine over network still work

Anyone updated to the new 10.5.3 and know if Time Machine still works over the network via AEBS?

I was hoping 10.5.3 would fix things for time machine/time capsule, I had issues with it hijacking my laptop and the network doing fsck_hfs. So I looked forward to fixes, had been doing only back up now, since having to reset everything. I tried it, it took an our to get past preparing, then had 15 meg out of 2 gig backing up, stuck there for hours. I finally killed it by dismounting the disk. When my disappointment reduces I may try a fresh start. I am sure they worked very had on it.

Does Time Machine Backup When You are NOT logged in?

I do not normally leave myself logged in since there are multiple people in my family and they have their own accounts.
Does time machine run backups when I am not logged in?
Does it wake the computer from sleep to run a backup every hour? Day?
If TM does not backup when I am NOT logged in, should I leave myself logged in by switching users back to the login screen?
(On a side note:) Is there a way to make it so that when a screen saver activates, and someone hits a key, it goes back to the login screen instead of the desktop?

Yes, in System Preferences->Security check "Require password to wake...."
You can also tick "Log out after x minutes of inactivity" which would require a new login.
