Time Machine Size Limit on OS X Mavericks

Before mavericks I was able to set a size limit to time machine back ups, but now on mavericks I cannot.
I used:
sudo defaults write /Library/Preferences/com.apple.TimeMachine MaxSize (size in bytes,i.e. 512000 for 500gb)
In terminal.
But now in mavericks there is no longer a time machine plist, or at least I can't find it anymore.
Does anyone know how to set a limit using mavericks?

same problem here... Have you found any solution?

Time Machine size configuration

How do I manage my time machine backup sizes?
I need to be able to limit/quota the time machine size. I can quota per user per system, but that would impact their home directories. I've tried to modify the sparsebundle size, but that just horks up TIme Machine.

Shame nobody cared to describe this working solution... I am running Mavericks and struggling to find this setup/config

Is it possible to downgrade to mountain lion with the help of a time machine backup after having updated to Mavericks?

Is it possible to downgrade to mountain lion with the help of a time machine backup after having updated to Mavericks?

Just to be clear, if by downgrade you mean uninstall, then the answer is technically, no.
You can't uninstall an OS. You can erase and re-install the old OS, but if you don't have a prior backup of your data, you'll lose it during the erase procedure.

HT203177 I have not backed up my computer using Time Machine since before I updated to Mavericks. It has been "preparing backup" for a half hour at least and shows no indication of how long this may take. Is something wrong?

No. TM has to look through your entire drive contents and copy them all. This will take some time.
Once the first backup is made, then subsequent backup will be much quicker, depending on how much data has changed since the last one.

Restricting Time Machine size with LaCie NAS Share

I have a question regarding quotas for my LaCie 2big NAS. I am using Time Machine on my MAC OSX. I had no issues in the Time Machine setup and initial backup so far. I wanted to limit the amount of disk used by Time Machine. I created a separate Share for Backup on the NAS. However, I am not able to set a quota based on the Share. I can only set the quota based on the user. I tried to create a user named "backup" which had a quota but the Time Machine sparse bundle has my own username (i.e., "my_username") as the file owner (it seemed like I needed to have the backup and my_username for the NAS with permissions on the Backup share). Time Machine identifies the disk as "Backup - My_NAS_Name" with the 500 GB limit which I established. This seems like it is working but I am not sure about the best approach.
Why doesn't the 2big NAS support Share quotas? It seems to be supported on other LaCie products. Is this the best way to configure or use the NAS to restrict the TIme Machine available size?

Thanks, Pondini, you make a good point about using a USB drive with my Airport Extreme. The snag is, the Airport Extreme is in the same room as my computer, so it doesn't get over the co-location/fire problem. I suppose I could plug the Airport Extreme into my ethernet in another room, but this might compromise its coverage.
To protect yourself against fire, flood, theft, and direct lightning strike on your power lines, you need secondary, off-site backups. Get a portable external drive (or a pair, to alternate). Periodically do separate backups to it, and take it to your safe deposit box, workplace, relative's house, etc. CarbonCopyCloner (which I use in addition to TM), SuperDuper!, or the like would be fine for this, although you could use TM by just doing a +Change Disk+ each time.
Frankly, looking back 20 pages through this thread, I am astonished by the number of problems that people seem to be having with Time Machine. It rather looks like a flakey piece of software that's best avoided.
Don't be misled by what you see here. TM works just fine for most people. They only post here when there's a question or problem. Many of the questions wouldn't be necessary if Apple's documentation was better, and most of the problems are either things people did without knowing they shouldn't, or hardware problems. You'll find similar threads on the CCC and SD forums, too.

Time machine stuck in 'preparing backup' in mavericks

I have just upgraded to Mavericks on my macbook pro 13" 2009. I have a 2TB time capsule which has run perfectly for years under several OS X. I also have an external HDD to which I copy an image of my internal HD once a week using Carbon Copy Cloner.
Since upgrading to Mavericks the whole 'backing up' has become a total nightmare. Backing up using CCC is fine. Backing up to the time capsule using Time machine has now become completely unusable.
I have verified both my internal HDD and the time capsule. I have repaired permissions. I have disconnected my HDD as I now realise that this is a problem under Mavericks but I do feel let down by Apple. Its their software, their hardware and their time capsule and it is clearly failing. Even a USB memory key (essential for me) throws everything off!!!
Has anybody any bright ideas? I am not a guru by any means but have a working knowledge of the various bits of kit.....sort of.
Thanks in advance. First time poster so looking forward to some help here.......

This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running a program at the instance of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait about a minute. Then paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

Using a time machine backup of Mountain Lion on Mavericks

I have just installed Mavericks with a clean installation from Mountain Lion. I have a time machine backup of Mountain Lion, but I do not want to use this backup to restore my system because I have a lot of problem and I would like to be sure that is not a problem connected to the software.
Can I use the previous time machine disk as backup of the new operating system without losing the previous backups?
If I use it, I cannot restore the system with the "Mountain Lion" state with the migration assistant, is it true?
Thanks

No. Time Machine will be replacing your existing backup with a new one of your Mavericks system. If you wish to replace Mavericks with Mountain Lion, then I suggest you replace it with another backup of Mountain Lion, if you have one. Otherwise, if you've permitted Time Machine to run since installing Mavericks, then you not longer have a Mountain Lion backup.
You will need to go to your Purchases page in the App Store and try to re-download your Mountain Lion purchase. If you can, then after the Mountain Lion installer downloads and opens quit the installer - do not run it. Now do this;
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
Use DiskMaker X to put your installer clone onto the USB flash drive.
Make your own Mavericks flash drive installer using the Mavericks tool:
You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this command line after the prompt in the Terminal's window:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
Wait for the process to complete which will take quite some time.
Now, run the installer flash drive, erase the hard drive, and reinstall Mountain Lion. You can then use Time Machine just to replace your data from your Home folder.

Restoring applications from time machine after a clean install of Mavericks.

I had recently upgraded from Mt. Lion to Mavericks from app store. But after few months I thought it was being buggy and slow. Last week after taking a complete time-machine backup I formatted the computer and clean installed Mavericks again. Now I am trying to restore just few handpicked applications one by one. Most of the apps are either not working or asking me for keys. Is there any other way to restore apps from Time Machine? Because all I see is that it just copy pastes the folder from the backup, and does not restore the prefe

If I were you, I would not restore your applications from the backup, more if you want the preferences back. Performance issues will be back and you may need to reformat the hard drive again.
Instead, the best thing you can do is to reinstall your applications manually, so you will not be transferrind files you do not need

Time machine won't back up after Maverick install

Installed Maverick today on macbook pro, then have been unable to back up to Time Machine to my Western Digital 3TB drive. Last back up was successful just before install earlier today.
Time Machine Error "Files can’t be copied onto the backup disk because it appears to be read-only.
and a second message
Time Machine couldn’t complete the backup to “My Book”. Files can’t be copied onto the backup disk because it appears to be read-only. You may need to repair or reformat the disk using Disk Utility. If the disk can’t be repaired, you must use a different disk for backups. Open Time Machine preferences to select a different backup disk.
First restarting after Maverick install I received an error message that the disk "my book" could not be repaired.
When I go to get info on the external drive, under sharing and permissions it sayes I can read only, and I cant figure out how to change this everything to try is grey'd out.
Any help in fixing the problem and understanding the issue.

I'm also having this issue. I havn't had it before.
Any help would be appreciated.

Time Machine "inherit" after emergency downgrade to Mavericks

(iMac; 3.6GHz Intel Core i5; 16GB 1333 MHz DDR3 memory)
I was having many kernel panics after upgrading to Yosemite. After thorough hardware diagnostics (no hardware problems), the Genius Bar guy suggested downgrading to Mavericks 10.9.5, which he did in the store by wiping the hard drive and installing 10.9.5.
From the latest time machine back up drive (WHICH HAD BEEN BACKING UP FROM YOSEMITE), I copied my apps and files across in small groups and so far so good re: kernel panics. This process was not done via time machine interface, simply by dragging off the drive from newest backup.
Now, I would like to resume using that same drive for time machine backups from 10.9.5. And I believe I want to "inherit" that existing drive, so my future Mavericks back ups are ADDED TO but do not REPLACE the current Yosemite back ups.
The scary thing, in setting up time machine preferences is that this drive is showing " oldest backup: none // Latest backup: none " I'm afraid of going farther because I do not want this drive to be wiped during backup, for fear that kernel panics will return during that process and I could lose important data or ALL of it for that matter.
So, (1) Do I understand inherit correctly ? (2) How can I keep the current backups on this drive and ADD the future Mavericks backups?
thanks!!!!

HT204350 USB Time Machine backup drive not visble in Mavericks Migration Assistant

Hi all,
Yesterday I updated my dad's iMac from Snow Leopard (SL) to Mavericks. Seemed to work ok apart from the fact that turning on iCloud wiped out the calendars. In order to get the calendars back I restored from the most recent SL Time Machine backup. This turned out to be a big mistake! It did get the calendars back but stopped all programs not included in the OS X install to stop working!
I then managed to get a bootable flash drive installer for Mavericks sorted out and installed a fresh copy of Mavericks on the computer with the plan of using Migration Assistant to bring all my dad's files, settings, etc over. The problem is that when I open Migration Assistant and try to migrate from the USB Time Machine backup drive, the drive doesn't show up in the list.
I have also tried restoring from the Time Machine backups that were made straight after the upgrade to Mavericks as I have exported copies of the calendars now and that was the only issue at the time but when I do that the restore fails after about 4.5% progress.
Any help would be amazing as my dad runs two small businesses with the computer and the down time causing quite a few issues.
Thanksin advance!

If you synchronize any of your calendars with a server such as iCloud, disable that synchronization. Quit Calendar.
Triple-click anywhere in the line below on this page to select it:
~/Library/Calendars
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A Finder window should open with a folder selected. Enter Time Machine and restore that folder from the snapshot you want.
Relaunch Calendar and test. Your calendars should be as they were when the snapshot was taken. If you don't sync with a server, stop here. If you do sync some of the calendars with a server, select each one in turn and then select
File ▹ Export ▹ Export…
from the menu bar. You'll get ICS files with the filename extension ".ics". Re-enable sync. Usually, all the calendars you just restored will be deleted. That's not a problem. Create a new calendar on the server for each one you exported and want to sync:
File ▹ New Calendar
Then import the calendar from the corresponding ICS file by double-clicking it. Follow the prompts to import the new events to the calendar you just created. For calendars that you don't want to sync, just import them again. They'll appear in the calendar list under On My Mac.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

Time machine keeps OSX from updating to Mavericks - how do I fix?

Keep trying to update my old computer to Mavericks. It's currently at 10.6.8 and totally updated. Everytime I go to install Mavericks, when it gets to the window where you choose where to save it, I try to pick my Hard Drive but I get an error message that says I can't use hard drive because Time Machine is installed on that disc. I've gone in and deleted that program... I don't even use it. I don't know or care what time machine is... I just want to update my computer. But even after deletion, and a restart, I still get the same message.... HELP!

Hi PChick,
Thanks for visiting Apple Support Communities.
Try these steps if you are not able to install Mavericks on your Mac hard drive due to a Time Machine backup.
Follow these steps so that you can install on the disk.
Important: You should have a current Time Machine backup on a different disk.
Note: If you do not need the backups that are located on your installation volume, you can simply erase the volume with Disk Utility instead of following these steps. Erasing the disk will result in all loss of all data on it, so be sure you have backup copies of any data before erasing.
Start up from the disk you want to install on.
Move the "Backups.backupdb" folder from the root level of your hard drive to the Trash. Enter your admin password if prompted.
Important: Do not empty the Trash unless you have a backup on a different disk and want to delete the Time Machine backups from this disk.
Move the "Backups.backupdb" folder from the Trash to the desktop.
Install.
These steps are found here:
OS X: Cannot install on a volume used by Time Machine for backups

Time Machine does not work after installing mavericks

After I installed maverick on my imac, my time machine backups don't work anymore!!!!
I have a normal portable HDD attached to my Imac with time capsule backup from before mavericks was installed.
I also has a Buffalo NAS as a second Time Machine Backup.
TIme capsule does not recognise my Buffalo NAS and tells me that it is not available. It has previous backups from Mountain Lion for sure!
My portable HDD keeps saying "Preparing for backup" for eternity.
Please, APPLE, what is going on with mavericks? Regretted upgrading.
My backup is 31 days behind because of this! Unacceptable!
But what is strange is that I can connect to my portable HDD and Buffalo NAS as a drive. What I have been doing is to copy and paste the important stuff into the drives. But it really defeats the purpose of time machine, right?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Time Machine size discrepancy / backup fail

Hi! For a few weeks now my Time Machine backups have ceased to work, with an error that they are too big for the drive. While I only have a 500GB drive, my total size of the backup has always been well within that (thanks to the exclusions I have set up, mostly for my video projects).
I've finally had a chance to look through my files and determine that the only truly gargantuan folder was indeed my Videos folder, but it is excluded.
Here's the nub of my problem / question:
My Time Machine panel under Options says the estimated size of the full backup is 274 GB. But backups fail with a message that the backup requires 849GB! That's way more than the 20% overhead I know TM requires in addition to the backup size.
This seems to be the key to why my backups are failing.
Can anyone suggest a course of action?
Thanks!
Adam

ARGH! Would you believe that - only days after I fixed it with the combo update - it happened again?
Well, it did. "The backup requires 847.90 GB but only 93.79 GB are available."
847 GB? The "Estimated size of full backup" in the exceptions window is 276.88 GB.
Just like before.
I did run a Repair Permissions after the combo update as suggested... just to rule that out...
Just in case it's at all helpful, I'm including the info from the Dashboard widget that reveals Time Machine log info - first for the last successful backup, then for the first one to fail.

Time Machine not making hourly backups since Mavericks upgrade

Recently upgraded to Mavericks from Lion 10.7.5 (took 14 hr.). Since then, when I enter Time Machine (without being connected to my external backup drive) I get a notification "your time machine backup disc can not be found". The only options given are to "set up time machine" (which I have done) or "cancel". My previous backups to my external hard drive are shown in the back ground but can not be opened and there are no hourly or weekly backups shown.

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
