Multiple Mac Backup

I've just bought an iMac with a 500Gb SSD. That's not much storage, so I need to archive stuff and remove it from the internal drive on a regular basis. I also still have my macbook pro which I'll use when I need to be portable and my wife will use as her main computer. Can anyone suggest to me an elegant backup solution for backing up both machines and also ensuring security against HD failure. I was wondering whether I could network the machines and have a common backup and backup backup if you see what I mean.
I think also that the backup needs to be separate from the Archive thing. I do music projects and when a project is finished I'll want to remove it to the archive. Obviously the Archive needs a backup solution too.
I didn't get a fusion drive, because I was told that this could create problems with audio processing.

You are correct that the backup and archive must be on separate drives.
You are also correct that the archive should be backed up.
Rather then doing a backup of a backup, what I choice to do instead is to do multiple backups using different software for each.

Multiple Mac backup to external HD

I want to backup 3 Macs to a single 1T external HD partioned with space for each. The HD is FW attached to an iMac (OS X 10.5.5), which is ethernet connected to another iMac (OS X 10.4.11) and an eMac (OS X 10.4.11). I want the backup on the 1T HD to be a bootable copy of each computer's internal HD.
I've tried using Silverkeeper (comes with LaCie drives) and Carbon Copy Cloner, but neither is able to make a bootable backup. Each can "see" the external HD but don't want to acknowledge it's a simple backup. Dragging and dropping the internal HD image from each computer to the external HD results in an alias being created, not a real copy.
Ideally I can get this system to work such that it scans for anything that's changed on the source HD's and only copies that to the destination HD, but if it takes copying everything each time that would be OK for me as well.
Any suggestions on Mac configurations or software that will enable me to do this? My goal is to have the external HD set up in one place and backup all the machines without moving the HD around to different rooms.
Thanks for the advice!

I have SuperDuper! backup my Macbook 10.5.5 system to my PowerMac G5 10.4.11 over ethernet into a .sparseimage file.
It is not bootable, but I can always put the system needing to be restored into Target mode and restore the data from the .sparseimage if I need it. And for systems that can not be put into Target mode, I can always install a minimum Mac OS X, then mount the backup volume and restore the .sparseimage that way.
I mount the the backup volume on my PowerMac G5 and SuperDuper! then mounts the .sparseimage.
If you create an alias of the mounted volume, it will save all the connection information for the volume. You can then create an AppleScript (or Automator workflow) to open the Alias, causing the network volume to be mounted, then invoke SuperDuper!.
Using a .sparseimage also means you do not need to partition your disk. Each Mac can just use its own .sparseimage
It is possible that you could do something similar for other backup utilities, but your *Mileage May Vary*.
If everyone was running Leopard, you could use Time Machine, as another Mac running Leopard can provide the same services as a TimeCapsule. I'm doing this with a Mac mini and 3TB of external Drobo storage.

MULTIPLE MAC BACKUPS BUT MACBOOK SLOW

We bought a 2 TB timecapsule and are backing up 2 imac's. We have a 3rd MacBook and the backups seem really slow and seem to be backing up the whole computer every time 19 Gig instead of the changes made. Is this norman?

Upgraded: New Mac, Setting up iPhoto Library From Multiple Old Backups

Over the years (Jaguar to Snow Leopard), I've had multiple Macs in different locations (work, home) to which I've loaded photos from cameras into multiple iPhoto libraries. As these Macs have died (G4s, G5s), or I've been forced to upgrade, I've made a backup on CDs and DVDs of the iPhoto libraries (different versions of iPhoto over the years).
Now I've got a brand new Macbook Pro and I want to put all these photos into one library on one disk. I don't care much about preserving photos edited in iPhoto (I use Photoshop for serious editing), nor do I have particular album or roll data from these old libraries that matters. I just want to get all the original photos into one library so I can search and access them all in one place.
I have always found the way iPhoto organizes the photos on disk a bit confusing, especailly when it comes to backing up and accessing the files at the Finder level. And now it seems things have gotten even more dumbed away from the user in "package" w/ the latest iPhoto.
I would like to just have my photos in a folder, not a "package," but I would like to be able to search and organize photos and load them to my iPod Touch. (Maybe isn't the best application for me?) I'd also like my iPhoto folder to be on an external HD.
This is one of those grueling tasks I've been putting off for years. So many disks, so many libraries, how to get them all into one. I want to get it right once and for all, so I'll have all my photos on in one place and hopefully in a Finder-level folder that will be easy to back up and easy to port to my next Mac down the road in the future.
Can anyone offer any advice on the best way to proceed? Anyone else been through something like this?
Thanks in advance,
Babz

This is actually more simple than it seems as you
just want to get all the original photos into one library so I can search and access them all in one place.
So, create a Library: Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library' and import the contents of the originals from the other Libraries: (File -> Import, Drag to the iPhoto Window, Drag to the iPhoto icon on the Dock)
That's all your originals in a single Library.
I have always found the way iPhoto organizes the photos on disk a bit confusing, especailly when it comes to backing up and accessing the files at the Finder level.
It's actually quite straightforward, but the key is +you don't access the files at a Finder level+.
And now it seems things have gotten even more dumbed away from the user in "package" w/ the latest iPhoto.
Remember: iPhoto is a Database. Like any database, you need to manipulate the data via the db and not a back door.
Since iPhoto 7 (iLife 08) the old iPhoto Library Folder is now a Package File. This is simply a folder that looks like a file in the Finder. The change was made to the format of the iPhoto library because many users were inadvertently corrupting their library by browsing through it with other software or making changes in it themselves. That's why +you don't access the files at a Finder level+.
Want to see inside: Go to your Pictures Folder and find the iPhoto Library there. Right (or Control-) Click on the icon and select 'Show Package Contents'. A finder window will open with the Library exposed.
Standard Warning: Don't change anything in the iPhoto Library Folder via the Finder or any other application. iPhoto depends on the structure as well as the contents of this folder. Moving things, renaming things or otherwise making changes will prevent iPhoto from working and could even cause you to damage or lose your photos.
How the library is organised: There are various files, which are the Library itself and some ancillary files. Then you have three core folders
Originals are the photos as they were downloaded from your camera or scanner.
(ii) Modified contains edited pics, shots that you have cropped, rotated or changed in any way.
(iii) Data holds the thumbnails the the app needs to show you the photos in the iPhoto Window.
But none of that matters, as you never access the files via the Finder.
*To back up an iPhoto Library* make a copy of the Library on another disk. You can automate this process with Time Machine or many other back up apps like Chronosync or DejaVu. There are many, many other options. Search on MacUpdate.
I would like to just have my photos in a folder, not a "package,"
*How to do it:*
Simply go to iPhoto Menu -> Preferences -> Advanced and uncheck 'Copy Files to the iPhoto Library on Import'.
*What Happens:*
Now iPhoto will not copy the files, but rather simply reference them on your HD. To do this it will create an alias in the Originals Folder that points to your file. It will still create a thumbnail and, if you modify the pics, a Modified version within the iPhoto Library Folder.
*Some things to consider:*
1. Importing and deleting pics are more complex procedures. You have to to put the files where they will be stored before importing them. When you delete them you'll need to remove the files from the HD yourself.
2. You cannot move or rename the files on your system or iPhoto will lose track of them on systems prior to 10.5 and iPhoto 08. Even with the later versions issues can still arise if you move the referenced files to new volumes or between volumes.
3. Most importantly, migrating to a new disk or computer can be much more complex.
4. Because iPhoto has no tools for managing Referenced Files, if, for some reason, the path to the photos changes then you could find yourself resolving aliases for +each photo in the Library+ one by one.
My own opinion:
I've yet to see a good reason to run iPhoto in referenced mode unless you're using two photo organiser
If disk space is an issue, you can run an entire iPhoto Library from an external disk:
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
If you're concerned about accessing the files, There are many, many ways to access your files in iPhoto:
*For Users of 10.5 and later*
You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.
Uploaded with plasq's Skitch!
You can access the Library from the New Message Window in Mail:
Uploaded with plasq's Skitch!
*For users of 10.4 and later* ...
Many internet sites such as Flickr and SmugMug have plug-ins for accessing the iPhoto Library. If the site you want to use doesn’t then some, one or any of these will also work:
To upload to a site that does not have an iPhoto Export Plug-in the recommended way is to Select the Pic in the iPhoto Window and go File -> Export and export the pic to the desktop, then upload from there. After the upload you can trash the pic on the desktop. It's only a copy and your original is safe in iPhoto.
This is also true for emailing with Web-based services. However, if you're using Gmail you can use iPhoto2GMail
If you use Apple's Mail, Entourage, AOL or Eudora you can email from within iPhoto.
If you use a Cocoa-based Browser such as Safari, you can drag the pics from the iPhoto Window to the Attach window in the browser.
*If you want to access the files with iPhoto not running*:
For users of 10.6 and later:
You can download a free Services component from MacOSXAutomation which will give you access to the iPhoto Library from your Services Menu. Using the Services Preference Pane you can even create a keyboard shortcut for it.
For Users of 10.4 and later:
Create a Media Browser using Automator (takes about 10 seconds) or use this free utility Karelia iMedia Browser
Other options include:
1. *Drag and Drop*: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
2. *File -> Export*: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
3. *Show File*: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.
*To use iPhoto with Photoshop*
You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.
Note that iPhoto sends a copy+ of the file to Photoshop, so when you save be sure to use the Save command, not Save As... If you use Save As then you're creating a new file and iPhoto has no way of knowing about this new file. iPhoto is preserving your original anyway.
There's a lot of material there. By all means come back for clarification if you need it. But I strongly urge you to think very carefully before running a Referenced Library.

Can I use accounts in the Airport Utility to keep backup from multiple macs separate and separate?

Can I use accounts in the Airport Utility to keep backup from multiple macs separate and separate?

Backups from multiple Macs are always kept separate. Each Mac TM will create its own sparsebundle and will not interfere with others.
Using the accounts in AU will simply make each sparsebundle only accessible to that user.. ie it is a purely a security measure.. that is so weak as to be useless .. anyone can bypass it by pressing the reset for 1sec.
And what it will do is cut off everyone from their existing backups.. you will be warned when you set it up that what is about to happen may not be 100% goodness.. pay attention.. it is not.

Backup multiple Macs to external HDD

I have an iMac (OS X 10.8.2) with a new Seagate BackupPlus external HDD attached by thunderbolt. The external HDD has 5 partitions (all Mac OS X Extended Journaled format). 4 partitions are dedicated back ups for 4 Macs (the iMac connected via thunderbolt to the external HDD, plus 3 MacBookAirs (MBA's)). The 5th partition is just for storing random data (I realize TM won't back up the data on the same drive as the TM backups, but that's ok).
Following the steps FAQ #22 on the great pondini site http://pondini.org/TM/22.html I was able to set up Time Machine to back up my iMac (with the external HDD physically attached) AND I was able to setup TM on my MacBookAir (also running OS X 10.8.2) to wirelessly back up to the external HDD attached to the iMac.
I am now trying to do the same for wife and kids MBA's (i.e., get them to have TM back up wirelessly to the external HDD that is attached to the iMac on the same network). However, while I can get TM to backup my MBA, I can't get their to work, even though I followed the same steps on their "source" MBA's as I did on mine. The other MBAs can see the external HDD (attached to the iMac) and even remotely read/write to it (which I did as a test). TM on their MBA sees and lets me select the appropriate partition on the external HDD, but when I try to do a backup, after a few seconds TM stops running. It may be worth noting I also have TM backing the MBAs (including wife and kids MBAs) wirelessly to a TimeCapsule too... and that works flawlessly (I am trying to get my MBAs backed up on both my TimeCapsule and an external HDD connected to the iMac, so I have two backups).
The error log from TimeMachine Buddy on my wife's MBA shows:
Starting manual backup
Attempting to mount network destination URL: afp://melaniebernitz@Bradley%E2%80%99s%20iMac._afpovertcp._tcp.local/Mel%20MBA% 20External%20Backup

NAConnectToServerSync failed with error: 80 for url: afp://[email protected]/Mel%20MBA%20External%20Backup
Backup failed with error: 19
To try and fix, I have:
-- rebooted both machines.
-- ran "Verify Disk" on external HDD partition (verify disk finds no issues)
-- checked file sharing on iMac (again, the MBA's can read and write to the external HDD connected to the iMac with no problems so it has read/write/share "access" to the external HDD)
-- did full reset of Time Machine preference on my MBA per pondini.org/TM/A4.html
-- on the MBA's that won't back up wirelessly to the external drive, I can still "see" and select the external HDD (connected to the iMac) in Time Machine
-- tried running TM from different users on each MBA (including adminstrators, of course)
-- have shut off and re-turned on Time Machine
In case it helps diagnose the issue, here's the TimeMachine Buddy log for the my MBA (for which TM successfully completes the wireless backup to the external HDD on the iMac).

So, to make a long story short, even though the external HDD partitions are mounted and can be read by all MBA's....
-- My MBA has no problem backing up (via TM) to the external HDD physically attached to my iMac
-- Other MBA's can wirelessy back up (via TM) to TimeCapsule on my network, but NOT to the external HDD on the iMac (even though they can remotely see/share files on it).
All in all, I'm at a loss as to why it works for one MBA but not others (since I followed same steps to set up the MBA's for TM).
Any thoughts would be greatly appreciated
Thanks

What Partition Map Scheme does it have? (click the top line for the drive in Disk Utility's sidebar -- it will be shown at the lower-right). It should be GUID, but should work if it's APM (Apple Partition Map). If it's MBR (Master Boot Record), a Windows setup and often the way externals come from the factory, that may be the problem. I've never been sure of the details, but there's a message somewhere that says "not all partitions may be accessible" to Time Machine with MBR.
-- tried running TM from different users on each MBA (including adminstrators, of course)
It doesn't matter what user does the setup, or even does a Back Up Now, since the actual backup runs with "root" privileges (permission to everything). It sounds like you have the right Sharing setup on the iMac, but be sure each of those Macs is connecting as the right user on the iMac.
I've not done this myself with multiple Macs (I don't have enough hardware); only one Mac backing-up to a shared drive on another.

Looks like you've got some special characters in some names. I realize two Macs seem to back up ok, but oddly enough, sometimes such characters in names are a problem -- they'll work fine sometimes, but not always. See #C9 in Time Machine - Troubleshooting.
(I am trying to get my MBAs backed up on both my TimeCapsule and an external HDD connected to the iMac, so I have two backups).
You might want to reconsider using Time Machine for both sets of backups. It's prudent to want two separate backups in case one piece of hardware fails. But what if there's a problem with Time Machine itself, on one (or more) of your Macs? TM is pretty reliable, but no app is perfect. See Time Machine - Frequently Asked Question #27 for details, and the green box there for some alternatives (some of those may not work over a network. CarbonCopyCloner and ChronoSync do -- I use CCC locally, in addition to TM, but not over a network).

Using a seagate external drive with multiple macs

i got a 1TB seagate external hard drive for backup and transfer purposes... it had a little program to help set it up and i set it up for use with mac and pc ( only onther option was stricty this computer.) it works on my computer and a pc but when i tried transfering files from another older mac i have it showed that i could only read on that computer...
how can i get it to work with multiple macs...?

I have the oldest macbook (1.83. 2 gigs ram, 60 gig internal hard drive)
I have all my logic content on my external maxtor firewire 400 drive (usb 2.0 is actually faster than firewire 400) and everything is fine. the good thing is if your external drive has 7200rpm, but the ones with 5600rpm should do as well.
Once you drag your apple loops to logic from your external drive, logic will remember for the next visit. And when you are opening a project which is on the external drive , just find it with logic finder and all should be fine.

Time machine multiple macs sharing one HD via Wifi

I need help with time machine app.
I would like to use one external hd for multiple macs to backup with time machine.
I read about different method, the one that I think is better for me is to sharing the HD on a network.
I have one Imac and two macbook.
What I did is to connect the HD to the Imac and than I shared the HD volume with sharing files.
I create two accounts for the macbooks and then I connected them.
So far so good.
But I din't use this network configuartion for the first backup, what I did instead was to connects the different computers one by one with thunderbolt.
Now I had to change the destination dirve from the old HD (connected via thunderbolt) and the "new" shared HD - actually is the same drive!
I thought that the macbook time machine app just recognize the last backup and just makes a new one from that point.
But it seems doing a new backup. (Last backup: none)
It creates a new file Macbook of Alessandro.sparsebundle
Any tips?
thanks in advance

Same Account on Multiple Macs?

I am setting up a new Mac Mini to be used primarily as the "accounting computer". But it will also serve as a backup computer for the 3 users on my main Mac Pro when multiple users want on at the same time. So how do I handle the set-up of the new Mini? Should I create 3 identical users, with their same login names & passwords, on the 2nd Mac? i.e. So when I need to get on to check email, but my main puter is in use by another user, I can jump on the Mini & have updated access to my email??? Secondly, how do I keep Mail, Calendar, etc in sync on both machines?

jdehnert wrote:
My best suggestion would be to set your people up on one of the computers and have then share their home directories with password protection. You may want to do this on whichever system has more hard drive space. Then set them up again on the alternate system and make sure that they can connect to the main system to access their home directories. If you can train and/or convince your users to keep all of their files on the home directory space that resides on the main system, it could work.
This is more along the lines of what I had in mind. The use on the alt computer will only be to do a quick email check... I am in the process of setting all email accounts up as IMAPs... or internet surfing, etc. Any tasks that involve files from the main box will have to be accessed through sharing, then saved back to their account on that main puter... and this will be on occasion at most. And now that I've said all this, I can think of several instances where I've needed to interrupt someone because I needed to check my calendar... have yet to use iSync - does something like this allow me to sync my iCal to another computer?
So how should I handle the users on the 2nd Mac? Should I set up all the accounts there too... even if it might be for occasional use? And if I'm setting up individual accts, can I set up accts with the same login names & PW's on multiple Macs that are networked, without issue?
It just dawned on me that if someone is surfing the internet on the alt box, they might need their favs over there... although I'm the only user w/an extensive favs list. Truth be told, my network is a home business network. So far, the only other users on the main Mac are my kids... the network serves for home biz/personal tasks. One of my kids is a college student who uses the computer for all basic tasks plus web design & Photoshopping. Point is, I'm just looking for the best, simple solution.

How do I manage multiple macs on my Time Capsule?

I have a 2 TB Time Capsule 4th generation w/ multiple macs backing up to it. I want to be able to manage ALL files on Time Capsule. Is there a way for me to see all the data from all macs on time capsule, and delete those files if necessary? (This has to do with my kids going off to college and me needing to free-up space.)

See item #17 of this post.
If you want to delete all Time Machine backups for a particular Mac, just mount the Time Capsule's disk (probably called "Data" unless you renamed it), then drag the appropriate "sparsebundle" file to the trash.

Multiple Macs with multiple user accounts

I have a Mac computer connected to airport and use Time Machine for backups. This works well.
I have now purchased a second Mac and would like to include this second Mac so that I can move between Macs and work. There does not appear to be any mechanism to allow this.

After searching the web and the discussion here, here's my minimal impact solution for multiple Macs with multiple users in a household:
1) Set up Mac1 for myself only
2) Set up Mac2 for the wife and kid
3) Set up each Mac to backup to the Airport base station using Time Machine (this would create two separate backups on the Airport base station's drive, which from what I've read has its own problems)
4) On Mac1 setup "empty user accounts" for the wife and kid. These will not have any files in them - just an access mechanism. If they want to access their files, they can use Time Machine's "The Browse Other Backup Disks Option" to get their file from Mac2, work on it and then drop it in the Shared Folder. Next time they are on Mac2, remember to copy the updated/created file from the Shared Folder into their Mac2 user account. If possible, get Time Machine to not backup the "empty user accounts".
5) Do the same for me on Mac2.
Not the most elegant solution, but until Apple get off their backside and make this seamless, I can't think of anything else :-( .
P.S. iCloud is not a soluton since it costs hundreds of dollars a year, uses up intenet data allowance and is slow.

Can i back up multiple macs to the same hard drive

can i back up multiple macs to the same hard drive

Yes, you simply share the drive to the network.. in whatever way that is possible as you have given us no info.. over the network TM will create sparsebundles.. locally it can produce a straight backup ..

Time Machine for multiple macs - NAS or DAS attached to my iMac, which I then share?

Greetings
I currently have three macs - MBA, MBP and an iMac (newest generation). I'd like to use Time Machine for all of them.
Is it better to set up a NAS for Time Machine or can I use DAS that I woudl share (external HDD) attached to my iMac if they are all on the same network?
Also, is there any need for something like a Drobo or an external RAID array, if it's mostly for backing up and not for video editing? It would be used as a mnusic server to some degree. I've used a Drobo in the past (2nd gen) and find that I've spent a lot of time troubleshooting and fiddling with it over the years.
Thanks,
John

I am looking to add a Seagate NAS TM compatible to my network. I have 8 TB of storage w multiple Macs that I would like to backup to a NAS device.
Any advice would be welcome.

Using external NAS drive for Time Machine and multiple Macs

I just installed an external NAS drive from OWC's sister company Newer Tech. It is 500g with ethernet and usb2.0 connections. It works very well with easy setup with Time Machine with no hassle.
However, in very fine print that I missed in the ad, it supports 20 computers but not for Mac only for PC. OWC customer service said I could return it but I'll keep it anyway since it works well but only for one computer at a time in read/write mode.
Anyone know of a way around this? Are there any drivers from other vendors that would allow this to be used with the multiple Macs on my home network?

Very doubtful, but even if there is a workaround, you do not want to take that kind of risk with your backups.
