Time Machine with external HD

Guys, I have a problem in my Time Machine.The external HD is not found, but the mac recognizes the HD, only the Time Machine is not.What is very strange is that until a few days ago before the backup was working properly at this Time Machine HD.
I checked the disk using Disk Utility but not solved the problem. Can anyone help me?

When using time machine with external hardrive to backup, some music items from iTunes and some photos from iPhoto do not transfer to backup hardrive. What am I ding wrong? Using latest version of mountain lion.

When I use time machine with my external harddrive to back up computer, some music from iTunes library, and some photos from iPhoto library are missing when I check backup disk. I am using latest version of mountain lion. Am I doing something wrong?

First, Time Machine doesn't completely back up the iPhoto library while iPhoto is running. Make sure you quit iPhoto after making any changes to allow a backup to take place.
This simple procedure will clear your Time Machine settings, including both overt and hidden exclusions. If you have a long exclusion list that can't be recreated easily, you may prefer a more complicated procedure that preserves the exclusion list. In that case, ask for instructions. Otherwise, do as follows.
Triple-click the line below to select it:
/Library/Preferences/com.apple.TimeMachine.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu. A Finder window should open with a file selected. Copy it to the Desktop. Then move it (the original, not the copy) to the Trash. You'll be prompted for your administrator password. Reboot, recreate your settings in the Time Machine preference pane, and run a backup to test. If TM now performs as expected, delete the file you copied to the Desktop.

Using Time Machine with External Hard Drive

Hey everyone,
I had a few questions about Time Machine that I hope someone could answer for me.
I bought my first external hard drive in August, the 1 TB WD My Book for Mac and when I set it up, I configured it to Time Machine, and not the WD software.
I have an extensive music collection, which was my main reason for buying the external hard drive in the first place.
Anyway, when I plug in the hard drive and let Time Machine do the back up, I've noticed that it's backing up the same files every single time, and is eating up a lot of space on the hard drive.
Since I am mainly using this drive to store my music, I was wondering if there was an easier way to do things:
-Is there a way to not back up my documents, photos, applications, etc, every single time I plug in my HD?
-Is there an easy way to find my music on the drive? For example, some Time Machine back-ups have different files on them... i.e. my back up from August 10th has certain music files that do not exist on my backup from November 10th, as I deleted them from my computer after they were backed up to the external HD. I'd love to be able to see all of my music in one place, rather different versions of my music folder on different days.
Any help would be greatly appreciated.
Thanks a lot.

Hi,
1. Your Time Machine should should do the full backup of your computer just once and then only diffrences between backups - whenever you plug in the drive.
If that's not the case something is misconfigured.
2. You can exclude folders (documents, pictures etc) from being backed up. This is in in Time Machine Options (right bottom corner.
3. The drive is (most likely) indexed by Spotlight. However, provided those are backup files I would advise against browsing and searching them directly. This can damage the backup itself.
4. I cannot work out the exact scenario you are using - but the ideal (proper one) would be to have all your music library on your computer and only backup on your external drive. This you should not have to browse and use until you need to restore files.
5. If you keep your music library solely on the external drive - it should be not in the backup files.
Also such practice is risky as all drives crash sooner or later and you will lose your music.
Best would be to keep all music on the computer and backup onto your external drive.
Or
if the music library is too big for your computer you may keep it externally - but Isuggest you get one of the external hard dirves with RAID1 or higher. This will keep your music safer lest one of the drives packs up.
Let me know if you want me to elaborate on any of the aforementioned.

How can I restore my data from iCal? I didn't make any backup, but I use time machine with an external HD. I deleted iCal when I deleted my gmail account. I have tried to restore, but I can only restore the iCal software and not the data.

So what is your question?
If you forgot your encryption password:
Warning: Make sure it's a password you will remember or write it down for safekeeping. If you encrypt an iPhone backup in iTunes and forget your password, you can't restore from backup and your data will be unrecoverable.
If you can't remember the password and want to start again, you must perform a full software restore and chooseset up as a new device when iTunes prompts you to select the backup from which to restore.

HT3275 Since updating OS to Mountain Lion from leopard, I get the following error message when trying to backup with time machine on external drive. Could not complete backup to media share. The network backup disk does not support the required AFP feat

Since updating OS to Mountain Lion from leopard, I get the following error message when trying to backup with time machine on external drive. "Could not complete backup to media share. The network backup disk does not support the required AFP features." What are AFP features and how do I get Time Machine to backup to my current external backup?

This means that your NAS does not support the required encryption. Update your NAS to the latest firmware or ditch it and buy a Time Capsule (they are the most reliable when using TM).

Can I increase the capacity of Time Machine with an external hard drive connected to Time Capsule?

Can I increase the capacity of Time Machine with an external hard drive connected to Time Capsule via the USB port? My current Time Machine has a total capacity of 1TB. I'd like to double or triple its memory. I don't want to use the external hard drive in lieu of the Time Capsule hard drive. I'd like to use it in addition to. Just don't know if/how it's possible.
This is another one of those questions that I've searched the web for answers, and have gotten tricky answers back. So now I'm trying to introduce a clean slate to the mix.
Thank you for your time!

Well, what you mentioning is possible. However, I don't know whether it's supported (as in, "easy to set up."). Time Machine officially supports backing up to a locally attached drive, to a machine running a Time Machine server (i.e. running OS X Server software), and to a Time Capsule. I don't know that it officially supports a drive attached to an AirPort or to a Time Capsule. Though I know some people have gotten it to work.
Best I can say is to try it. Plug the drive into the Time Capsule, ensure it's shared on the network, and then try and set it as a backup target from a machine in the Time Machine backup panel (you'll need to ensure it's mounted first). If it works, you're all set.

How to use Time Machine with an external drive?

Hi…I’m new to this, I hope someone can help me=)
I’m trying to back up my Macbook Pro 10.6.8 using Time Machine with an external drive Seagate Backplus Slim. I’ve tried several solutions that I’ve found through different forums but still wouldn’t work.
Every time I opened Time Machine, it has this appearance:
Then when I click “Select backup Disk”, it goes on like this:
And after I click “Set Up Time Capsule”, it has this:
It keeps saying that it couldn’t find AirPort wireless, even though I have good WIFI connection.
Anyone know what I should do? Please help….Thanks everyone

Setting Up Time Machine with a Partitioned External Hard Drive

I recently bought a new external hard drive (MyPassport) and I was advised to partition it in order to keep my movies/music files separate from the rest of my files. So I partitioned it, but now I can't figure out how to set up the Time Machine with 2 separate hard drives. Is there a way to set it up so that I can use Time Machine for both, one for movies/music and one for everything else?

Is a WD My Book Studio Desktop 3TB Hard Drive - FW 400/800, USB 2.0, Apple Time Machine Ready external hard drive bootable with my Powerbook G4 12" PPC 10.5.8?

Sirs or madams,
Is my Powerbook G4 12” PPC 10.5.8 'bootable' with a Western Digital My Book Studio Desktop 3TB Hard Drive - FW 400/800, USB 2.0, Apple Time Machine Ready external hard drive? Western Digital says officially no, but that it MIGHT be. I primarily live in China and bought a datastorage.com.cn Clearlight s400+ external hard drive enclosure with a 320GB disk drive a few years ago in China. My computer 'boots' fine from it, but since I got it in China all the paperwork, etc. is in Chinese; my Chinese isn't quite sufficient enough yet to read it. But there are references to something called "SATA", whatever that is.
My level of computer 'under the hood' knowledge is extremely low. I've been told that SATA has some relationship as to whether or not an external hard drive will boot a computer via the Firewire connection, something relating to 'interface', which I assume is how separate electronic gadgets work, or don't work, with each other.
I frankly don't care much for computers, the internet, or their related gadgets such as all these fancy phones. I longingly reminisce about the days when there were no such things. I use a computer & the internet because I have to, and unfortunately unlike a car where one doesn't have to have 'under the hood' knowledge to operate it, just knowledge of the steering wheel, brake, gas, etc., one seemingly must know a ridiculously great amount of 'under the hood' knowledge, including jargon, to operate computers.
So, please try to respond accordingly; thank you.
If this particular external hard drive won't, for certain, be bootable with my computer, can you advise as to what readily available brand/model would be in the 3TB range for a similar price, roughly $150ish??
Thank you very much.

Mr. BGreg,
Thank you very much. "...under the covers...". I think you meant "under the hood", as in a car. I suppose "under the covers" would be man/woman interfacing, which I am familiar with!
Actually, I'm back in the US now for a few months. I looked at the OWC web site, but only cusorily so far. I'll contact them; they appear knowledgeable about Apple computers.
As to what you wrote about Western Digital's cases, I certainly wouldn't want a poor case. In China I had over time gotten 3 different external drive cases, 3 different Chinese brands, and separately bought Hitachi brand disk drives that 'simply' plugged into the cases. The drives are roughly 80GB 120GB and 320GB. The two larger ones are in cases that have Firewire plugs/jacks, which are bootable with my computer.
So my understanding, as you wrote, has been that my Powerbook will boot from an external hard drive, provided it connects via Firewire, and the disk drive itself is 'normally' formatted with however my computer's own disk drive is formatted, (HFS OS extended (journaled) or some such??). So I was left wondering why Western Digital would indicate that even though their such-and-so external hard drive case/drive was Firewire capable, that they would then say it would not be bootable with my Apple PPC computer......
Well, anyway, since you indicated Western Digital's case quality is suspect, then I'll try OWC and disregard Western Digital.
Naturally, OWC should be able to address this, but your thoughts are also welcome. You mentioned the OWC cases are good with Apples. Would the disk drives OWC supplied with the cases also be of relatively dependable quality?? From my so far only cursory look at their web site they appear to have various options, including case only options where I could insert my own or their own drives. These sorts of options seem preferable, also along with quality components.
My Powerbook has been in use since 2004. In China I put in a 1.25 memory 'chip' in the bottom and installed the 10.5.8 operating system, which I understand are the maximum workable with my Powerbook. When I inquired with Chinese friends if my 1.33 GHz processor could be taken out and a more powerful one put in, they said it wasn't feasible because in my particular computer my processor was, as I recall them saying, soldered/'permanently' connected with the 'motherboard', that it would just be easier to get a new computer.
I would be with them and they would nonchalantly open it completely up showing me all its tightly arranged 'innards' while at least giving it a good internal dust/dirt clean job for cheap lunch and a beer (& so much dirt/dust/lint there was!)...these are the same folks who build the things of course...fast moving hands with tiny screws flying everywhere, but everything 100% all back in place when finished.
My Chinese friends also said that nowadays Apples are not as well built as when my Powerbook was built, that nowadays an Apple's life expectancy was considerably lower, so I fear that when I get a new computer that, though it will be more up-to-date and powerful, etc., it most probably won't last near as long as my Powerbook has. They also said that in an older computer the fan was often the first component to go bad, and if a new one couldn't be easily found, as they said was my case, then you're just left with having to get an entirely new computer. Part of why I dislike electronic computer gadgets generally is that they are obsolete so quickly.
So, anyway, thanks very much for your information.

I am trying to get an answer to whether or not I can successfully use Time Machine with an external HDD connected to an airport extreme? Some forums say yes, some say no.

I am trying to get an answer to whether or not I can successfuly use Time Machine with an external HDD connected to an airport extreme. Some forums say yes, some say no. I'm also curious about formatting the hard drive to work both on my wife's MacBook Pro and my PC. Any help would definitely be appreciated.

You may be going on a recollection, that I share, that at one time Apple stated this would be possible:
In fact, Apple’s Time Machine Web page touted this very capability as recently as last Tuesday, as you can see from Google’s October 16 cache of the page
Effortless meets wireless. With a hard disk connected to your AirPort Extreme Base Station, all the Macs in your house can use Time Machine to back up wirelessly. Simply select your AirPort Disk as the backup disk for each computer and the whole family can enjoy the benefits of Time Machine.
But if you look at the current Time Machine page on Apple’s Web site, that text is nowhere to be found.
That was a long time ago, it has never been officially implemented, and at present they specifically say it cannot be done.
In summary, it may work, but probably won't, and even if it does it may not be reliable.

I use Time Machine with an external hard disc which has worked perfectly for some years. Recently Time Machine has aborted backups if the screen saver starts when back-up is in progress. I use a Maxtor OneTouch4 back-up system. Any ideas?

Has Apple recently up-dated my OS (Lion) such that every time the screen saver starts it disables Time Machine. I have to switch-off the computer and re-start in order to undertake a back-up. I have now switched of all screen savers.

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 this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in 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(s)?
After testing, reboot as usual (i.e., not in safe mode.)

Using Time Machine with a network Drive

I recently bought a WD My Book Live network drive to use as my Time Machine backup. I was previously using a USB external HD for Time Machine with no problems. I have set up the new network drive but when I go in to Time Machine to select it as the drive to back up to, it is not showing up. The only drive I see is my old USB external HD. I have the latest firmware for the network drive and I am running Mac OSX10.5.8. Any suggestions?

If you bought the WD in a USB enclosure it probably came formatted with NTFS (Windows). Time Machine can't use NTFS drives or SMB (Windows) network shares as a backup destination because that format does not allow the proper permissions to be set. If this is the case with your drive, open Disk Utility and reformat your new drive (NOT you system drive!!) with HFS+ aka 'Mac OS Extended (Journaled)' and then the drive should show up as a target selection in Time Machine.

Using Time machine and external HD at the same time

Dear All
I'm intending to buy an external HD both for the purpose as a external HD and for time machine use.
Is this possible? If so, how do I configure it?
Thanks.

Apple Partition Map works just fine on an external HD (including booting from a clone made with SD). GUID is only required for the internal HD on Intel-based Macs. There is a lot of misinformation going around on this topic.
Is Apple spreading the misinformation Barry? This OP originally asked about Time Machine and an external drive. He later asked about bootable backups. I tried to take all that in consideration in my reply. Apple has consistently said in everything that I have read in the Knowledge Base that when using Time Machine with an Intel Mac to use the GUID partitioning scheme.
There are also recent posts around these forums, as well as around the internet, where folks have had bootable volumes that were not GUID and they encountered strange behavior on their Macs that they report was resolved by making sure that their bootable volumes on external drives were in the GUID partitioning scheme.

Time machine to external USB vs. indexing of that USB

Time machine to external USB vs. indexing of that USB
To all who plans to use external USB as Time Machine destination.
Problem was found with 10.9.5. Other versions possibly affected as well.
No idea if external storage connected through cable of other kind affected as well.
Mavericks on iMac 2013 late. Addressed external USB is used as second Time Machine target.
It worked pretty well few months long after had declared that external usb as TM target.
Suddenly the backup gets stuck. It can keep to stuck for-ever.
However users here do not accept to be confronted with this state for-ever.
Longest attempts were approx 10 minutes long, in our environment and circumstances long enough to be called "for-ever".
Stuck in the stage of size calculation.
Part. Repair by Disk Utility did not help.
Unmount, disconnect USB, reconnect did not help.
Verify the part by Disk Utility did not help.
New Spotlight exclusion rule for all partitions on that external was the only measure which helped.
Before encountering the problem one could observe that partition verification by Disk Utility
always failed. Partition repair prior to Verify was always necessary for Verify to succeed - it is not normal!!!

Problem using Time Machine with Seagate BackUp Plus Pls HELP!!

I have a late 2006 iMac (running OS 10.5.8) & am trying to back up using Time Machine with a new Seagate BackUp Plus drive. When I select the Seagate drive in Time Machine it tells me I msut first erase the (Seagate) disk. When I hit ERASE, I get a Time Machine error : COULD NOT UNMOUNT DISK. I see from various posts that 10,5 & 10,6 have issues with some external drives so want to upgrade to Mavericks (to get around this incompatibility issue): HOwever apparently my iMac is too old (by 1 year) to allow this. Can anyone give me any advice on how to get my iMac content backed up via Time Machine using the Seagate BackUP PLus drive I bought (becasue it is supposedly "compatible with PCs & Macs".
Thank you!!
Wendy

Your Seagate drive should work just fine. If it doesn't have any important data on it, try re-formatting it with Disk Utility to blank it out. Or run the Disk verify/repair and see if you can get it to fix any problems.
I have a Drobo FS too. You probably need a firmware update, they issued one a while back to fix problems with Time Machine. Use the Dashboard or download it from their support site, http://www.drobo.com/support/updates.php
Just curious how long you let it run after it "stalled". If it is a big file it could just be taking a while to copy over, do you see activity lights on the USB drive? The first time you use time machine let it run overnight, it's going to take a while, after that it will update quickly.
While you're at it, you might want to verify your start-up disk too with Disk Utility.
