I have 2 Macbooks each with an account for me and one for my wife. I use one Macbook logged in with my account and my wife uses the other Macbook only logged in on her account. We both make regular time-machine back-ups each on a separate external disk. Is it possible to update her account on my macbook using her external disk without overwriting my stuff on the same Macbook and vice versa?

Time Machine does not do individual accounts. It records the complete drive. So if you were to use her TM backup on your Mac it would make your Mac just like hers. Both yours and her account on your MAC.
Just copy the missing files over from her Mac to yours. If there are differennt programs on each then they would need to be installed on both.

Is it possible to make 2 time machine back-ups on the same disk

Hi, i have 2 MacBook Pros, I have a time machine back-up for the newer one on my 500GB hard drive
I went to boot camp my other mac and it says I have to format the hard-drive, so I want to back everything on the old mac up, is it possible to make a seperate time machine back-up on the same external hard drive as I don't want to overwrite the back-up for my new mac? How can I do this
Thanks

you might have mentioned this before, but once I have partitioned my external drive, how can I go about re-formatting the old mac hard drive and then restoring my data back onto it?
You don't have to re-format it first; you need to erase and restore to "pack" everything into the first part of the drive so there's enough room on the rest of it for +Boot Camp+ to make a partition.
See #14 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).
Then use +Boot Camp+ to make the second partition.
Also, would it be better to run the OS X install disc, re-format the hard drive, and then when running setup assistant migrate all my information from the time machine back-up?
No. You'd have to install OSX, then use +Setup Assistant,+ then download and install the "combo" update (and other updates) to get back to the version of OSX you're running. And you might have to re-authorize and/or reinstall some 3rd-party apps.
If i do this, at the moment Im running snow leopard but the install disc is simply leopard, will this matter once I've migrated all my data across?
Do not use a Leopard Install disc to restore a Snow Leopard backup. It can copy everything, but the result either won't start or will kernel panic on startup. You must use a Snow Leopard Install disc.

Will existing Time Machine back ups build after 1 account migration

I have one i-Mac happily backing up with Time Machine to an external hard drive.
I have just bought a second i-mac (the old one's filling up) and propose to use migration assistant to move an admin account from the old to the new i-mac leaving two other accounts (and their files etc) on the old one. I see from some posts that it seems as if Time Machine will start a new back up series for the new i-mac's back ups (cos its a new MAC address). But what about the old i-mac? Will that continue to extend the existing (old) Time Machine back up files, albeit without my transferred account and its files? I'd like to end up with the old i-mac continuing to work with and build its Time Machine back ups (less my account and its new files) and have a new back up series from the new i-mac building to a separate partition on the external drive.
Second minor point: I have read that putting a partition on the external drive is the best way forward as it will stop competition for space and allow changes in one set up in future to have no impact on the other. Is this the best way forward?
Does this all make sense?
Sorry but I can't see an answer in the forum to what must be a reasonably common issue in this expanding mac world.

I then tried to move it (TM back up files) off with Restore, whilst preserving the TM back ups but I couldn't seem to do it to the i-Macs hard drive nor to partition that to allow this to happen (assuming the lack of a discrete partition was the problem).
That's likely correct. This only works if you restore one entire partition to another, and check the +Erase destination+ box.
The problem was that I could not (maybe for the same contiguous reasons) create a new partition on the old i-Mac just to temporarily move the TM back up to. Without it I could not 'empty' the WDC firewire drive and partition it prior to returning the TM back ups to it albeit contiguously in a dedicated partition.
Unfortunately for me to retain the TM back ups for the account I moved to the new i-Mac, I will have to leave that account on the old i-Mac as well. I can't see a way around that? If I delete the account on it then surely I will lose the ability to Log onto it and then to click TM and see back in time on that account?
If I understand you correctly, that will be true eventually, but not immediately, as TM will, eventually, delete it's copies of anything that's no longer on your internal HD. That will depend, of course, on how long TM can keep it's backups. But while they're still there, if you log on with Admin privileges, you should be able to view the old backups.
Not sure I explained myself clearly. Sorry. Having understood from your earlier help that 'migrate' actually means 'make a copy in another place', I have the migrated account in two places: one now dormant, on the old i-Mac and two, where it is migrated to (the new i-Mac). But TM continues to back up all accounts, indeed everything, on the old i-Mac by dint of its MAC address. So to see the migrated account's past history I assume I have to access the version on the old i-Mac. To put it another way, when logged into one account on the old i-Mac I believe it is not possible to see the TM history and files of another account on that i-Mac despite TM backing the entire HD. You have to be logged in to that account to see it. On the new i-Mac, with its different MAC address, TM is busy creating the first TM back up and I assumed that in the migrate it did not bring TM history as I had read that it is MAC address specific.
The only issue (apart from having this account's history spread over two machines (pre-today on the old i-Mac's TM and today onwards on the new i-Mac) is that I have all the files on both machines. I am not worried about security only unnecessary usage of disk space. It isn't critical, there's lots of it, but it just seems wasteful and untidy. Unless you guys know otherwise?
If I understand what you've done, you do have duplicates of the current contents, but only one copy of the old backups (on the old F/W drive).
On the old i-Mac I have the two accounts I wanted to stay there plus the now dormant account I migrated. TM continues to work away at memorising ALL these although there will be no further changes to the dormant migrated account as I will not be running it on the old i-Mac. On the new i-Mac I have the migrated account of which TM is now creating its first (huge) back up but starting today. There is no history here. So I have copies of everything; its just that the old history of the migrated account remains on the old i-Mac and a new history (does that make sense?) is building from the new one. My point was that if I were to delete the dormant account from the old i-Mac, then I could not access it to use TM with it. I believe TM only shows the history of the account and screen you're in at the time?
There is an option in TM that will allow you to selectively +Delete all backups of+ selected items. +Enter Time Machine,+ locate and select the item(s), click the "gear" icon in the Finder window's toolbar, and select the +Delete all backups of ..+ option.
What you can't do is, keep the backups of only previous versions of things that were changed or deleted. It's all or nothing.
Not sure I understand this. What would have been nice but I do not think is possible is to have moved the account to the new i-Mac together with the TM's back ups of that account and continue to build it up (whilst having access to its history) on the new i-Mac. If that were (is?) possible I could have totally deleted the old account and with it its files from the old i-Mac, freed up some HD space and had a full AND growing TM history all on the new i-Mac.
Many thanks for staying the course and for your continuing help.

HT201250 I have thousands of pictures on my Mac. If something happens to my Mac I don't want them lost. I do time machine back ups to an external hard drive once a week. Is this good enough for making sure my pictures don't ever get lost?

Purchase a couple of these when they go on sale.
Start burning all the photos onto DVDs.
At least you'll have all your photos if your computer, time machine or any other backup you use goes bonkers.

Can I use my time capsule for time machine back ups and as an external storage device?

I have a time capsule and have set it up so that my time machine back ups are saved on it, but I would also like to use it as an external hard drive. Is this possible?
I know nothing about computers so please tell me in very basic terms. thankyou!

By external hard disk we usually mean one plugged into the computer by USB or Firewire or Thunderbolt.
None of those works on the TC.. it is plugged in by ethernet or use wireless connection.. that means it is a network drive.. not an external drive. The difference might not mean much to you.. but it is totally different to the computer. In the former case the computer has full control of the disk. In the case of the network drive, the disk is controlled by the TC firmware and the files are stored and accessed by network. This has large implications.
So here is my standard response.
Store files on the TC.
This is asked several times a day.. obviously people are struggling with their latest SSD being too small.
The TC is not suitable for network file server.. but many people having no choice press it into service as such.
Major issues.
1. No backup.. no way Time Machine can backup a network drive. No place to backup to.. So all your files will be at risk. And you will need to buy a third party like CCC to do backup.
2. The TC cannot be partitioned and mixing TM backups and data is not great. It was and is and ever shall be a backup device for Time Machine.
3. The drive is slow to spin up and quick to spin down.. there is no control. In fact the TC is so lacking in controls for even the router side.. that you cannot do more than the most basic of setups.
The following are controls on the hard disk side.
Reformat it. You can name the share. You can do a full archive of the whole disk. This will go at a speed of aprox. 30-50GB/Hr so calculate how long an archive of a full 2TB will take.
4. iPhoto in particular can easily corrupt its entire library with wireless networking causing a disconnection to one photo. Even if you do this;;; do not move your photo library... you have been warned!!
Even apple btw say don’t do it.
http://support.apple.com/kb/TS5168 Although mostly about FAT32 it adds network drives.
5. iTunes can constantly lose connection to the library. The disk is slow to respond.. itunes on the computer will constantly spit out errors. Even in the midst of streaming the TC can spin down the disk due to caching.
6. Do not use any live files on the TC no matter what else you do.. if you edit files in whatever program the file must be on the local hard disk.
7. The only suitable location for most libraries is a computer. You can plug in an external hard disk.

Can I make one iphoto library from two time machine back-ups?

Hi
I have recently purchased a new Mac Book. I previously had two MacBooks, which I backed up with time machine onto two separate external hard drives.
I did a straight transfer of all data from one of these time time machine back-ups to my new laptop. I'd like to migrate select data from the second time machine back-up to my new Mac Book, and I'd like to start by transferring photos.
My laptop has an iphoto library, so I would like to know if I can import select photos from this second time machine back-up, and how do I do that?
many thanks
Linda

First you need to restore the second Library from the back up. You need to restore the whole library, you can't just gather bits of it, I'm afraid.
Once that's done you have two Libraries. The easiest way to do what you want is to merge the Libraries with the paid version ($20) of iPhoto Library Manager This can be set to avoid duplicates. See the Help on it for more.
This is the only way that will get all the versions and all the metadata.
Other than that you'll need to export from one Library and import to the other.

How do I prevent my hard drive being used for time machine back ups?

I want to install Snow Leopard but it tells me that the OS cannot be installed because the disk is being used for Time Machine back ups. I don't recall setting up my hard drive to be used this way (why would I?!) but now I can't seem to

Did you have TM turned on at any time? If so, and if you had no external hard drive attached, could it be that it created its own backup on a portion of your hard drive? I don't use TM, but I believe I read that this may be possible. Take a look at Disk Utility (Applications > Utilities) and report what you see on the left - under the top heading, is there more than one partition showing, such as here:
(I have two partitions: one for Snow Leopard, the other for Lion) - what does yours show?

External hard drive for time machine back-ups

Can anyone please suggest the best external hard drive to use for time machine back-ups on my iMac?
I also use a 1TB external hard drive for my iTunes library, but I've noticed that it can be slower to access the music than if I used the iMac hard drive......any suggestions? My iTunes library is currently sitting at around 200GB.
Thanks.
Brian

i'd recommend a firewire 800 drive. many folks here speak highly of drives supplied by [OWC|http://eshop.macsales.com/shop/firewire> and [LaCie|http://www.lacie.com/us/products/product.htm?pid=11156].

No, each drive is treated separately. Sorry!!

Excluding temporary user accounts from Time Machine back-ups

I have some temporary user accounts in addition to the default Guest account on my iMac. I currently have Time Machine backing up my entire system (the default TM setup). However, I'd like back up only my admin and permanent user accounts from now on.
Having done a little research, I believe I have the answer but want to make sure I'm including all the relevant directories. I believe the answer is to add the specific user folders to TM Preferences > Options > Do Not Backup. e.g., if my hard disk is named "MacintoshHD" and I want Users 'Account1' and 'Account2' to be excluded from all future TM backups, I would add these folders to the Do Not Backup folder:
/MachintoshHD/Users/Account1
/MachintoshHD/Users/Account2
So 2 questions:
1. Are these the right folders to make sure Account1 and Account2 are never backed up in the future?
2. Are there any other folders that i am overlooking?
Is that correct? Thanks in advance for your help!

Can I use One Hard Drive for 2x Time Machine Back Ups and another partition for all my data?

Hi Forum,
I am planning to but a RAID disc set up, but if i get a 2 disc set up, on one disc, can i have:
Time Machine back up for one Mac
Time Machine back up for 2nd Mac
Anothe partition for all my data.
then have that RAID'd to second disc?

no one?
and if this set up was on one disc, and one partition for one TM was for the Mini that has this drive attached, would TM back up this whole drive 2x TM Partitions and 1x partitions with data on, ok? it wouldn't get confused by trying to back itself up

I have an issue with time machine, it doesn't find the Lacie external driver it use to use. it is the same drive that I usaly use for time machine back ups. It is corectly plugged. What can I do ?

Hi,
I'm trying to back up my macbook with time machine on the Lacie external driver I usualy use for this, but today my computer doesn't find the driver. I haven't done back up in 6 month.
Today, the Lacie driver is pluged and running, but the computer just does'nt find it.
what shall I do ?

Some things to consider:
Is the drive mounted, i.e., visible via Finder and/or on the Desktop?
Is the drive still selected in System Preferences, Time Machine? If not, use the "Select Disk" button.
Is Time Machine still turned on (System Preferences, Time Machine)?
Can you see the drive (and mount it) using Disk Utility (in your Utilities folder)?

HT201250 can an external portable drive be used for both time machine back ups and for additional storage or to sync files?

I use a seagate freeagent Go drive to keep a copy of important files. Files that I use with some regularity. I sync the drive every few days to ensure I have the latest. It is a old school method, but works well. I realize that not all things are "backed up" as they would be with a real back up, like time machine.
Can one device drive do both or should I use two different drives?

How can I remove old Time Machine back-ups for a Mac I no longer have??

So, i am trying to back-up a brand new MBPro to my Time Machine but it says there's not enough room. Only 13.5 GB avail and need 284 GB. Is there a way to go into Time Machine and delete all the old back-ups from my former MBPro? (I've already migrated all the files and data to the new MBP from my iMac, also on the same Time Machine.) If I could wipe out the old MBP back-ups that should create enough room.

Delete the backups.
