Mountain Lion-Time Machine Questions

Hi all,
Recently I bought a new Macbook Pro and upgraded to Mountain Lion. This laptop comes with one internal hard drive ~ 750GB. I have two questions regarding Time Machine:
1. Can I partition my disk into two partitions so I can use one partition for Time Machine backups?
2. Can the partition for Time Machine backups have less space than the other one?
I know the disavantages to do so, but I just want to know if it is possible. Does Time Machine allow it?

Can I use a mountain lion time machine back up on new mavericks macs?

My macbook retina was stolen at my school. I was wondering because I used time machine having mountain lion, does it affect anything when if i purchase a mavericks macbook pro? the just announced one. I have all my pictures (iphoto) in that last back up. Can i use a mountain lion time machine back up on new mavericks macs? My macbook retina was stolen on August 16? So I don't know if there was an update on my mac that might affect it in any way...

It's ok you can use your ML TM to transfer your account. iPhoto library and other things will be upgraded when you open the apps.
At the end of the Apple article it says:
Migrating a Time Machine backup to a new Mac
When you get a new Mac, you can transfer all of your applications, files, settings, and other information from a Time Machine backup you've already made. When you start up your new Mac for the first time, the Setup Assistant asks you if you would like to restore from backup. If you've already set up your new Mac, you can use theMigration Assistant (located in Applications/Utilities) to do the same thing.
After Migration Assistant completes the transfer and you select your existing Time Machine backup drive, you will be prompted with "Inherit Backup History". Once selected you will be able to continue to use your existing Time Machine backup on your new Mac.

Mountain Lion & Time Machine

Since downloading mountain lion, time machine has been trying to back-up more than 180 GB of data when I only have a 4 GB hard drive. Status box says it will take 40 plus days. Is there a fix?

Mountain Lion Time Machine over Snow Leopard TM

Is it save to create a Mountain Lion Time Machine backup on an external hard drive with a Snow Leopard Time Machine backup? The TM Preference panel is showing "Oldest backup: None" and "Latest Backup: None". Will Mountain Lion erase the prior Snow Leopard TM backup? I don't want to lose my prior backups.

I intended to ask: "Is it SAFE....."

Can I run a Mountain Lion Time Machine Back up if I have a Snow Leopord boot up disc?

HI, I have a new hard drive in my Mac after my old hard drive crashed.
The only boot up disk I have is a Snow Leaoprd (which came with the computer). However, I had since upgraded to Mountain Lion. My most recent Time Machine Back ups were all on in Mountain Lion.
My question....If I use the Snow Leopard boot disc, will I be able to restore the Mountain Lion back up through TIme Machine? Or do I need a Mountain Lion boot disc?
Thanks!!

Restart with the Command-R keys held down to get to the Mountain Lion recovery volume that you can use to reinstall or reload from backup, or if your drive has just been replaced and does not have this, then if your system was made in 2011 or later then it likely has an internet-recovery option to load these tools, which can be started by booting with Option-Command-R held down.
Alternatively you can create your own external recovery drive using Apple's Recovery Disk Assistant tool (http://support.apple.com/kb/dl1433) to use if your system does not support Internet Recovery and you need to access these tools. To boot to this external drive once created, boot with the drive attached and the Option key held down, and then select it from the boot menu that appears.

Crashed OS MacBook Lion Time Machine Question

I have an older back up of my MacBook in Time Machine on a external hardrive.
Is is possible to add to the backup in target mode? The computer will not boot right now, but I can get to the volumes via target. I can access the revovery HD when I hold down the option key starting up.
The MacBook has some sort of infixable sibling error, which is getting pregressivly worse. Additionally I've up graded to Lion since the Origional back up and partioned the drive, so it wouldn't really match the origional Time Machine back-up.

I really appreciate both your efforts but let me clarify a few things here before you continue posting incorrect information.
#1 - I have not done anything in the Finder that will hurt anything. Opening a folder in finder is like going to the terminal and running a "ls" command.
#2 - The reason for my original post is becaue this is def. a bug or undocumented feature. Time Machine backups should be backwards compatible.
There is no reason for me to open Time Machine and not be able to open an older backup done in Snow Leopard, UNLESS, it is an expected issue. If this is the expected behavior, the first time one connects the drive, the system should provide some type of warning.
Time Machine displays my older backup dates in Time Machine, but I can't select them to read, restore or anything. Then I went to the finder to open the connected USB drive to confirm if the files were there or not, as my hard drive space is still occupied.
You CAN manually copy files from a Time Machine backup drive. This causes NO ISSUES, unless you start messing with the files that Time Machine uses to organize the data being displayed on the app.
I am a systems engineer, web developer, and systems analyst. I work on multiple operating systems (Unix, Windows, Solaris, Linux all flavors, and Mac OS). I have been working with operating systems since the MS-DOS no-Windows era. There is a very slim chance that I will mess up any operating system, especially OS X.
So, let me re-phrase my question: Is OS X Lion Time Machine backwards compatible or can it not ready Snow Leopard Time Machine generated backup files?
Thank you for any well informed replies.

Hi all;
I recently had to get rid of my 2013 MBP running mountain lion. In the process, I had to to a time machine backup to an external HD to preserve my [then] current data.
Now I am replacing that computer with a brand new MBP with mavericks.
My question is– what do I need to do to get my data back on to my new machine from that backup?
Any help is appreciated!
Cheers!

Mountain Lion Time Machine backup to USB drive super slow

I recently upgraded the MacBook Air to Mountain Lion. The time machine backup is SUPER SLOW even when doing it on a USB 3.0 Drive. It currently showing 2 days for 100GB backup. I was able to copy the same 100 GB of files on to the same hard disk in less than 1 hr. This is so slow that i might be better off managing back ups manually or just writing a small script to do it. But before I do so wanted to check if anybody else has the same issues.
Regards
Uddhav
Update:
Turning off the spotlight on the external hard disk helped improve the speed dramatically. Brought it down from 1 GB in 1 hr to almost 1 GB / minute.
System Preferences --> Spotlight
Add the Drive to the exceptions list. It will say this is a time machine disk so except the time machine folder everything else will be added to the exception list. Say Yes and thats it !!!
Now says 19hrs still a lot according to me but much better than 2 days.
Any body has any additional tips /tricks please share !!
Regards
Uddhav

That may indicate a damaged index. Keep an eye on subsequent backups -- if they take a long time, and/or show "indexing backup" on the Time Machine preferences panel for very long, you may need to delete it, so OSX can recreate it. See the pink box in #D2 of Time Machine - Troubleshooting for instructions.

Is there anything else on the drive (in the same partition)? If so, that's usually not a good idea. See Time Machine - Frequently Asked Question #3 for an explanation.

Yes, that's quite slow, especially if your Mac supports USB 3.
If it doesn't, it should be running at USB 2 speeds, which for a full backup should be, very roughly, 40-50 GB/hour.
See the rest of #D2 in the Troubleshooting link for other causes of slow backups.

Mountain Lion, Time Machine and How Best to set up an external HD?

Hello,
I'm just about to upgrade to Mountain Lion. (2011 MBP running Lion). Before I do that I would like to back up with Time Machine. My question is how best to set up the external HD before I back up and then upgrade.
The hard drive is brand new and I haven't formatted it for use yet. It is 1TB in size and the hard drive on my MBP is 500GB (currently using around 300GB).
Am I right in thinking that Time Machine will overwrite older back ups if there isn't sufficient space on an external hard drive?
How would you use the new set up the new, obviously larger, external drive. I was thinking of possibly partitioning it 750/250 and utilising the 750 for time machine back ups and the 250 for other stuff.
Any thoughts?
Cheers

Where can I find calendar library in mountain lion time machine backup

Hi together,
I just had a series of new hardware and problems with the software. In december I had to buy a new MBP as the motherboard of my old one was damaged. So now, with mountain lion, I only have made one backup with time machine so far.
A few days ago I bought an iPad for the first time. Thats why I was reading the instruction for icloud and tried a few things. And there I made a mistake and all calender entries were deleted.
Thought: no big problem, as I have a backup. BUT I cant find the calendar files in the backup. I know, that the library is only shown in "Go to + alt-key", but I dont find it in the backup. (I tried also an terminal command written in a community thread, but nothing happend)
Please, can anybody help me?
Thanks a lot in advance!!!!

If you synchronize any of your calendars with a server such as iCloud, disable that synchronization. Quit Calendar.
Triple-click the line below 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:
File ▹ Import ▹ Import…
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.

Restoring Mountain Lion Time Machine Backup in Lion.

I need to downgrade my RMBP from Mountain Lion too Lion. If I use the internet recovery to restore it to Lion, will I then be able to reinstall all my programs from a Time Machine backup?

OK, I;m back up and running. Found out that /Library/Applicaiton Support/Adobe was in two places. One was at the root level and another was in my account area. Each had similar files but the root one had the ones I was missing.

That seems unusual unless you changed drives.
If you upgraded the drive it sees the computer as a different one to the original backup..
I am not sure that it isn't better to do a fresh backup but you can try and inherit the old backup..

Will a Mountain Lion Time Machine backup restore to a Lion MBP?

I have two computers:
(1) My iMac late 2009. This is upgradeable to Mountain Lion.
(2) My MBP late 2006. This is running Lion, but is not upgradeable to Mountain Lion.
If I upgrade my iMac to Lion and my iMac needs repair will I be able to restore from Time Machine to my older MBP?
Thanks,
doug

Yes, I would have the same problems with CCC - if I upgrade my iMac to Mountain Lion.
If I don't upgrade, then it works just great. I unmount the CCC clone from one computer, attach it to the other computer and do a reverse-incremental-backup to the other computer and - voila! - I have synchronized my two computers!
It's the only way I know of synchronizing two computers.
I've been doing this for several years now with no problems.
It probably only works because the OS is the same and the hardware on my late 2009 iMac and late 2006 MBP are sufficiently similar. Both use Core 2 Duo cpus.
But if I upgrade to Mountain Lion (or, upgrade my MBP to an i5 or i7 cpu) I will lose the ability to do this. So on travel, I would have no easy way of synchronizing apps and files.
Of course one easy solution is just "don't upgrade." It's not like anything is particularly broken now. But it's always fun to have the latest OS.
I'm just not sure of the best strategy for having everything I need for travel if I want to use the MBP. I guess I could always switch from this quick synchronization process to a tedious "all afternoon and evening" process of moving files and folders over.
The kinds of files I'm talking about are source files I'm working on, VMs - all the typical stuff people have. Photos. Whatever.
I know how to do it manually. It's just a time-consuming nuisance is all.
One thing I'm doing is moving away from "On My Mac" folders in Mail and doing everything in IMAP. That should help. I also have LogMeIn installed. So I could always get something if I forgot it. And I have more stuff in DropBox and Evernote. That also helps.
Thanks,
doug

Lion cannot see mountain lion time machine backups

I have just had the HDD on my 2010 iMac changed under the 1TB replacement program. Before wiping my original HDD I made sure my time machine back was up to date. Originally my machine was installed with Mountain Lion, the new HDD has just Lion. I have just tried the recovery utility to restore using time machine and all it can see is my updates before I installed Mountain Lion. Presumably Lion cannot see Mountain Lion backups or something else. Does anybody know how I can simply get my most upto date time machine backup to restore the system.
Thanks

FYI I updated to Mountain Lion and still cannot do a full recovery from any Mountain Lion backups. The backups exist as I can see them in Finder and also when running the Time Machine app. In the app I'm able to restore individual items, but I don't want to waste my life doing this I just want to restore my system.

Mountain Lion time machine problems.

Not long after updating to Mountain Lion, my time machine backups started failing. When attempting to backup, it is getting stuck at the "looking for backup disk..." phase and causing my computer to freeze.
To clarify, for at least a few days I had routinely completed a number of backups using time machine after the initial upgrade to Mountain Lion, so I don't think it is a problem with indexing a new backup etc.
Suggestions? Thanks.

Ha, yep, I've been poking around on pondini.org/TM but haven't yet found anything on being stuck at "looking for backup disk..."
Found a discussion of a similar problem when going from 10.6 to 10.7 here: http://lime-technology.com/forum/index.php?topic=13852.0. It sounds like after waiting 45 minutes or so the backup disk was finally found and the problem was resolved. I'm going to let it run for as long as possible and see what happens...
