Time machine backup to usb disk

How do I set up a USB disk attached to an airport extreme as a time machine backup device?

First please be aware that Apple does NOT support Time Machine backups to HDDs attached to the AirPort Extreme Base Station. However, if you still wish to do so, you simply need to first use the AirPort Utility to share out the attached USB drive, and then, 'point' Time Machine to this drive.
For details on how to set up a Time Machine drive, please check out the following Apple Support article.

Problems with Airport Extreme Firmware 7.6.1. and Time Machine Backups to USB Disks

I found that when I upgraded to Firmware 7.6.1 my Airport Extreme was no longer able to maintain afp server connections to USB disks mounted to the APE. If I power cycled the APE it would work for a while and then fail again. This even applied for connectins on gigabit ethernet, not just wifi. Consequently my Time Machine backups became unusable. Rolling back to 7.6 fixed it, but I permanently fixed this by changing the IPv6 mode from "Automatic" to "Host". No problems since then.

I hate to have to tell you this, but backing-up that way is unreliable and not supported by Apple. See: Using Time Machine with an Airport Extreme Air Disk.

PowerNap Time Machine backup? USB Data shuts off in sleep mode!

So how is PowerNap supposed to do a Time Machine backup when USB is turned off in sleep mode? Everything else seems to work, but when I wake my computer back up, I am greeted with a message that the external hard drive was removed improperly, and no backups were completed overnight.
I'm using a MacBook Air Mid-2012 and a 2TB WD External HDD that uses it's own power supply.

A USB drive should be fine.
Right before going to bed, I duplicated a bunch of large files and then went to sleep with my USB hard drive plugged in. When I woke up I realized that Time Machine did back up about one hour after the computer was asleep.

Time machine - backup of a disk attached via usb on a time capsule

Hi,
I would like to know it is possible to backup data with TIME MACHINE of an external disk attached directly to a time capsule via USB.
I use it as a network disk for all my Mac's to access at the same iphoto library.
Thank you very much for your help

To back up the drive, connect it directly to the Mac and remove it from the exclusion list in the Time Machine preference pane.

Can Time Machine backup a USB drive connected to Airport Extreme?

Hi all,
I have an airport extreme that I used to run a shared USB drive for the family. I have a network drive attached to the airport extreme which I used for Time Machine backups, how do I tell Time Machine to back up the USB drive also?
All help very gratefully recieved.

Thanks for your reply,
When I open Time Machine preferences I can either select a different disk to use as the backup disk or exclude items from the back up. I cannot find an option to add the USB drive attached to my airport extreme. Apologies if I am being a little dumb.

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 !!

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.
It will say this is a time machine disk so except the time machine folder everything else will be added to the exception list.
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.

How do I restore from time machine backup onto unmounted disk drive "disk0s2?" :-(

In trying to restore my MacBook Pro after a strange freeze, I seemed to have unmounted the main disk drive. So, I have no drive on which to restore my computer using my time machine backup. What do I do now???

Give this a try:
Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
See if you are able to get the partition to mount. If not select the Terminal from the Utiilities menu. At the prompt enter:
sudo mount disk0s1
Press RETURN and authenticate. Your password will not be echoed. Press RETURN again. I'm assuming you have a disk with one partition. If that's not correct, then do not use the above command.

Incremental backup from time capsule (time machine backup) to external disk

I have two questions regarding backing up a time capsule backup.
I would like to backup the time machine backup of my Macs from a time capsule to an external hard disk. The time capsule is a first geneneration one with 500 GB. The external hard disk has 500 GB as well with USB and firewire ports..
First question: What is the best way to connect these two hard drives - I am using a MacBook Air with two USB ports ?
Second question: What backup software could I use to do incremental backups - I tried ChronoSync but it is not picking up the changes of the sparcebundles ?
Thank you for every valuable advice
Regards

Backing-up your backups is generally not a good idea. If there's a problem with the original backup, it will be copied to, and perhaps magnified on, the copy.
You'd be much better off making "secondary" backups separately. See #27 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum), for some suggestions.
About the only alternative is to "archive" the TC's contents to a USB drive connected to it, but that's not incremental, and has other downsides as well. See #Q6 in [Using Time Machine with a Time Capsule|http://web.me.com/pondini/TimeMachine/TimeCapsule.html] (or use the link in *User Tips* at the top of this forum).

Time machine backup from USB stick doesn't work

Hi all,
I've got an MacBook Air (1st gen) with Lion, with a 80GB internal HD. This HD is quite full now, so I decided to move my rather large iPhoto library (c. 30GB) to an external 64GB USB stick. Up to that point, everything worked well.
I'd like to include the USB stick to my Time Machine Backup. The USB Stick is formatted as HFS+. It appears in the list of excluded drives in the Time Machine setup. If I click the 'minus' button to remove it from that list, it goes away, but comes back as soon as I leave the TM setup and reopen it. Accordingly, Time Machine does not generate any backups of the USB stick. The external Backup has enough free space to make a backup, so this should not be the problem.
Any ideas how I could fix that problem?
A workaround could be to use a 3rd party tool to backup the library. I tried Carbon Copy Cloner, but CC can not do incremental backups of bundles. Any recommendations?

I am having the same issue on my macbook air (end 2010)
I bought a 32gb usb stick and Time Machine always excludes it.
I assume that Time Machine should be able to backup it.
Could it be because it is a USB stick and not a USB hard drive ?
Also as a workaround could be make that a usb stick is reconnized as a hard drive ?
Any recommendations?
thanks

How to resolve errors (-50 and -8058) when moving Time Machine backups to new disk?

I'm trying to move my Time Machine backups (about 600GB total) to a new external hard drive. I started the process last night, but after an hour or so received two errors, each repeated multiple times:
"The operation couldn't be completed because an unexpected error occurred (error code -8058)."
"The operation couldn't be completed because an unexpected error occurred (error code -50)."
I opted to cancel the file transfer. I looked up the error codes but I'm still not sure what they mean. I found an old support article about error code -50 (Mac OS X 10.1: "Error Code -50" Alert Appears When Copying Files From a Remote Disk) and an old support article about error code -8058 that doesn't appear to be entirely relevant to my issue (Mac OS X 10.4: Error -8058, unable to eject when trying to copy a disc in Finder). I've also found a number of Support Community discussions, none of which are particularly helpful.
Questions:
What do these two error codes mean? Are the files that cause these errors somehow corrupt?
If I click "Okay" when the error dialog appears, are the files that are causing the errors transferred or are they omitted from the transfer?
If I transfer the files and click "Okay" when the errors appear, or if I use Terminal and cp -R as suggested in Mac OS X 10.1: "Error Code -50" Alert Appears When Copying Files From a Remote Disk, will I have trouble recovering files from the new backup disk?
Do I need to verify/repair permissions on the original Time Machine disk before attempting the transfer?
Is there some other method I should use (e.g. Terminal instead of Finder) to transfer the backups?
Details:
MacBook Air
Mac OS 10.8.5
Both the old and new Time Machine disks are formatted Mac OS Extended (Journaled)

The two drives are handled as separate drives, even if they have the same name.
In essence, the old backups are from a drive that's no longer connected; see #E3 in the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.

Time Machine Backups of Encrypted Disk Images, Part 2

Hi:
If Time Machine is backing up a hard drive that contains a subset encrypted disk image as part of its contents, and this encrypted disk image is mounted (in an unencrypted state) where the enclosed data has been changed/manipulated in any fashion, what and when does Time Machine backup?
In other words, does the data in the encrypted disk image only change when the encrypted disk image is unmounted? Or is it somehow backed up real time even when the encrypted disk image is mounted on the desktop in an unencrypted state while Time Machine is working?
Sorry I can't explain this very well, but hopefully the gist is clear.
Thanks!
(OS 10.8.2)

Time Machine doesn't back up a disk image file while it's mounted, whether encrypted or not.

Moving time machine backups to another disk

I'm trying to move my time machine backups one external drive to another. I'm getting an error that says "The backup can’t be copied because the backup volume doesn’t have ownership enabled."
I was told I had to check off Ignore Permissions for this disk but I have no idea where to do that. it is not in GET INFO. I am using Snow Leopard.
Any ideas how I can copy the time machine files from one disk to another?
Thanks.

I recommend doing as I suggested. Cloning is the only correct way to backup a Time Machine backup drive. If you have data on the other drive you don't wish to lose then create a new partition on that drive. See the following:
To resize the drive do the following:
1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.

I can't clone (Duplicate) my Time Machine backup properly via Disk Utility

I have an ext. HDD Time Machine backup sitting beside my 10.8 MBP.
I want to create an identical ext. HDD Time Machine backup, because it's safe to have 2 identical HDDs backing up my system.
But when I follow this apple guideline, a problem occurs:
Time Machine: How to transfer backups from the current backup drive to a new backup drive
URL: http://support.apple.com/kb/ht5096
The problem is I get a strange path even if I drop "Backups.backupdb" of 3TB1 (The source HDD) onto the root level of 3TB2, the destination HDD (I mean there's nothing in there so I just drag & drop onto the HDD). And the result is my new ext. HDD eating up about 60GB more space.
I have attached pictures of the paths for both Source HDD and Destination HDD, please look.
Why does it alter my file hiearchy like this?
Please help some high-level Mac guy thanks!

Why not just use TM to back up to 2 external drives. TM will alternate between the two when it backs up.
Alternately, you could have a 2 back up strategy like others have using SuperDuper! or Carbon Copy Cloner. Both are excellent 3rd party apps to clone your internal drive(s) and both have schedulers.

How long for Time Machine backup with USB v. 1

My hard drive might be failing. I'm going to backup with Time Machine for
the first time ever. I'll be using a 1 TB external hard drive. My Mac only
has a USB v. 1, so how long should this take? I read where someone said
that Time Machine said it would take DAYS to do it. Say it ain't so!! Any
ideas our there? Thanks!

See this for an indication of transfer rates these are theoretical speeds - real world is slower!
http://en.wikipedia.org/wiki/List_of_device_bit_rates
USB 1.1 runs about 1.5MB/s at full rate.
How much data is on your internal disk?
Wolfram Alpha says 1TB would take 7 days & 17 hours.
http://www.wolframalpha.com/input/?i=1TB+at+1.5+MB%2Fs
I would add more days to that time to account for the fact that USB 1 is slower (more like 0.7MB/s in my tests from years ago).
This is an appalling idea - your disk could easily stop working in the time it takes to copy.
Fortunately you have got the spec wrong on this iMac…
http://www.everymac.com/systems/apple/imac/specs/imac-core-2-duo-2.4-20-inch-alu minum-early-2008-penryn-specs.html
It has USB2 ports & Firewire - connect directly to one of those & the time will be much less (more like 1/2 a day).

Time machine backups present on disk but not seen

Hi. I just notice that on my macbookpro time machine is keeping creating the hourly backups, but I cannot see them anymore from the time machine interface.
All backup files seem to be on the disk, but whenever I enter the time machine I can only see the last one, as if I started the time machine for the first time.
Any idea why this is happening? And, more important, any idea on how to fix it?
I'm on a macbook pro with OS X 10.8.5; the time machine files are stored in an external USB disk.
Thank you for your support.

My TM did this after the upgrade to 10.9
When I first set it up, I just clicked to use the same drive I had been using, even though I'd just formatted it.
Apparently that causes the backups not to appear in the app.
So, here's what finally resolved it. I:
1. Opened Time Machine Preferences.
2. Turned Time Machine off.
3. Clicked "Select Disk...".
4. DELETED the TM disk I had previously selected.
5. Reformatted the TM disk once again.
6. Reopened Time Machine Preferences.
7. Reselected the newly formatted disk from the list.
8. Turned Time Machine back on, and let it begin backing up.
When I opened it the next morning, I had seven backups in the app to choose from.
