Hardware :: Time Machine Backup Failed / Disk Appears To Be Read Only
Jan 1, 2010
iMac 2.66 GHz, 640GB hard drive, 4 GB RAM.
I have a Western Digital external hard drive used by Time Machine. Worked perfectly for a few months. Now every day, I get a message that a backup failed because the disk appears to be read only. I launch Disk Utility, and run Verify Disk It finds nothing wrong. I ask Time Machine to back up again, and it does and continues hourly for the rest of the day. The next day, the same thing happens all over again with the read only problem.
Time Machine reported it failed backup due to the shortage of disk space. But I see the total space of partition is 192GB，the whole backup snapshot estimated is 177.56G.
The massage said that " failed backup, 52.85 GB is needed for backup but it's only 25.17 GB available."
I know it's 166.35GB of ancient snapshot still exist, but why not OSX to delete it automatically and release more space for new snapshot?
By the way, I can't delete those ancient snapshot in Finder manually, perhaps permission denied.
Info: MacBook Pro (Retina, 13-inch, Late 2013), OS X Mavericks (10.9.4)
This happens frequently lately: "Latest backup failed. Files couldn't be copied on backup-disk because it seems to be Read Only. After I "verify" the disk in Disk Utility, it works for a while, then the same problem. What can I do?
I have a 1tb external for time machine back up and have about 750 gb of stuff to back up. I was under the impression that when time machine backs up my stuff it will automatically delete the oldest backup to create room for the newer backup.
My problem is that i did a back up a couple weeks ago and then today i go to back up and it tells me back up failed only 718gb available for 740gb of stuff to back up
My time machine is not backing up my files anymore. Everytime I start it, it prepares for a very long time (maybe 30min or longer) and then eventually does start. But in the middle of the backup, an error pops up saying that I need to verify the space needed for the backup. But there is definitely space on my back up drive and Time Machine also recognizes the external harddrive. I've tried re-backing up a few times already but it doesn't work properly each time. I can still enter Time Machine and see the older back ups.
We just came back from vacation 2 days ago; I checked time machine. It says latest backup is delayed; then latest backup failed; next backup when disk is connected. I have a WD external hard drive. I check to see that it is connected to my IMac and is plugged in for electricity. Restarted my imac - same problem. There is no lite on the WD; does it mean it died? Or what can I try? It is less than 2 yrs old.
My orginial MacBook got stolen a few weeks ago and luckily my insurance bought me a new one. However, I have just managed to get hold of my external hard drive, which had my backuped time machine files on it.
So I went to my files from my time machine and this is what I did.
I went to the Time machine icon on the top of my screen and clicked on "Browse other Backup disks". I then clicked on my external hard drive and it opened Time Machine and then I found my latest update. I then clicked restored and the files got copied from my time machine to my new Mac.
The problem that I have discovered is that I restored my files incorrectly and that all I have just done is copied the files over and not restored my MacBook.
Now that I know how to restore my backuped files correctly, when I try and do it, I do not have enough space on my computer, because I still have the copied files on my Mac. I have tired to find the files without any luck on my computer. All I can think of is deleting my hard drive and start again, but I do not have the OS disks as Apple no longer supplies them when you buy a new Mac or it just didn't come with my new MacBook Pro.
This morning everything was fine, but then it happened out of nowhere.Usually my MBP does it Backups on a Synology DiskStation212j, but today it got some errors. [code] Since the backup is made on a NAS i can't use the DiskUtility to repair permissions..(My NAS doesn't have any Errors)
Info: MacBook Pro (15-inch Early 2011), Mac OS X (10.7.4)
I bought a new drive and need to get my Time Machine files off the old failed drive. I'm sure there are plenty of discussions about this but I can't find any. (I so dislike the new design for the support communities.)The old drive sometimes lets me access TM so I want to take advantage of one of those times to get everything across. I know it is a very slow process if it can be done
Info:Mac Mini 1.83ghz, Mac OS X (10.6.8), Great for a while.
The OS X 10.6.x Server running Time machine, it runs daily backup to external HD, it is fine, but for couple of days, it failed, is there any logs or message that I can read what is going on? The external HD connected with firewire 800 and it still have enough space, so I think it is not a space problem
I filled up a 250gb My Book external drive using Time Machine. Replaced it with 500gb My Book and now can't read the old 250gb one when I reconnect it. My iMac doesn't recognize it. (I lost a large picture folder that is now only on the 250gb drive).
I was a PC user who recently moved to mac. I have a macbook (intel 2.2GHz, 2GB RAM, 250GB HDD). When I was using PC, I backed up all my data to a network storage device (Buffalo LinkStation 250 GB connected to a 802.11g netgear router which is supplied by Sky) using a program called SmartSync Pro, which worked very well. Although I can connect to and mount the Share folder on this drive when the macbook is connected to the network, Time Machine will not back up to it. It wouldnt even recognise the disk on the network.
So I went onto the trusty internet, and found that you can get time machine to recognise the Share folder. (This was obtained from: http://blog.imulus.com/george/software/using-leopard-time-machine-to-backup-of-a-network/)See my comment on their page at the bottom, number 66.
It recommended entering the following in to the Terminal: defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
Before attempting backup I have to go into "Network" and select the Share folder by double clicking on it. This seems to mount the volume. After this, it can be seen in Time Machine as a potential backup destination.
However, this method does not work for me. Time Machine "prepares" for a while, then gives the following message: Time Machine error. The backup disk image could not be created.
More internet searching took me to macosxhints which suggests creating something called a sparsebundle image on my local system. (http://www.macosxhints.com/article.php?story=20080420211034137) Have not tried this yet as I thought it would be prudent to seek some help first.
Apple have deliberately disabled the ability for Time Machine to back up to network attached storage, (except of course to their proprietory Time Capsule):
Is this because time machine requires a network faster than 802.11g?
Is this because a time machine backup to a network attached storage device is unreliable and the data is corrupted?
I dont want to shell out more cash for a time capsule. I would prefer not to have to hardwire to an external drive (which I will also have to go out and buy). Any thoughts?
I have a external HD which has always worked fine under snow leopard. Since upgrading to lion I keep getting the following message The identity of the backup disk has changed since the previous backup.The disk may have been replaced or erased, or someone may be trying to trick your computer into backing up to the wrong disk. And after this the drive disappears from the desktop appearing agian only after restart. What can I do do rectify this? Delete and re-intialise the drive?
my TM wil not back up! It states that this backup is too large for the backup disk. The back up disk requires 573.50 GB but only 225.23 GB are available. The TM needs work space on the backup disk, in addition to the space required to store backups. Upen TM perferences to select a LARGER backup disk or make the backup smaller by excluding file.
Okay I;m sorry but obvioulsy I dont get this. I've never called Apple for help! I have every product they sell practically including Protection Plans I never used and no one will help me with this. My MAC is starting to have black or white screens and i can hear it running but it will not do anything so i have to reboot it, it screws up Enturage and then I have to rebuild that ( 5 times this year) anyway... I would like to back everything up- can I delete everything on the Time Capsule or Time Machine; god I dont even know what it is called Im so MAD... help if you can please. I'm going to have to take this to the genius people at the store and probably buy another computer but like before they will not save my files.
What can be done if Time Machine failed to save certain data to external hard disk, but I do have the old hard drive? I have a new IMac 10.9.2. The old IMac was hit by lightning/surge. Restored data from external LaCie disk but some information is missing. Apparently Time Machine did not save it to the external disk, or we just can't locate it. We do haves the old hard disk and will put it in a box to be able to access it.
So I bought a brand new WD 1TB Elements (USB) to use with Time Machine. I've never used a Time Machine before. I have a MBP13 with a 250GB disk, using the latest Snow Leopard, all updates installed. Formatted the drive to Mac OS Journaled (extended) and set it to use with Time Machine. Works until about 15-17GBs is copied over, than it fails:
1. If I start over it fails very soon after, no matter how many times I retry 2. No matter how many times I reformat it, it always fails 3. I tried one trick I googled - deleting the "inprogress" file - does NOT help 4. SMART status is verified 5. There are no problems if I verify/repair the disk.
I want to use Time Machine, but I don't want to have all my data sitting in the open on an external drive that someone can just carry away. Can I make an encrypted disk image, and have Time Machine use that as the backup volume?
I'm interested in replacing my 250GB HDD for a 80GB SSD. I want to use the old drive as a USB backup disk for Time Machine, but is 5400 RPM fast enough for this?
I keep getting message "time machine is read only".....I check "get info" for time machine disk and it is set to "read-write"..Can't backup any files....even though there is 71gb free on disk..
I just bought MacBook Air yesterday (the 80GB version), and love it! It makes a nice companion to my MacBook Pro. I have now one problem. How do I get my Time Machine backup from my Firewire disk to the MacBook since MBA does not have a Firewire port?
I just got a message that my Time Machine external backup disk is full. I have another external drive I can use, but buying drives every few months is going to get expensive.
I was wondering what others are doing in this situation.
Is anybody archiving the Time Machine backup? If so, what software are you using and where are you storing your backup?
What kind of backup plans are you using with Time Machine?
I'm no newbie but this one has me stumped. I can put file onto a Time machine backup disk that I don't use as a backup anymore but I can't take them off. The Disk still has some backups on it that I would like to keep. But I would like to use the extra space for regular file storage. What gives. When putting a file on the disk it asks for the password but moving them to the trash it will delete everything in the folder but it won't actually delete the root folder. So my question is
1. Can I use the disk and keep the backups on it? 2. How do I get permission to read and write to the disk
I have the new Time Capsule and am able to access it remotely just fine. However, because I'm stuck at school all day, I rarely get the chance to back up my Macbook Pro. Does anyone know of a way to have Time Machine backup to a remote disk, such as my Time Capsule? (I'm a Mobile Me subscriber, by the way)
I had to give up my Macbook Pro and am now going back to my Macbook. I have everything loaded on a Time Machine backup, but am having trouble getting to my Macbook. I bought a Leopard Install DVD back when they were released, but when I pulled it out I saw it is now scratched. Can I use a Macbook Pro Leopard install disk to restore my Time Machine backup to a Macbook? If not, is there any way to completely restore a computer from a Time Machine backup without an install disk?
The problem is that full Os backup should be about 155 GB, but it tries to backup whole disk 1 TB. It works fine for first full backup 155 GB (I have exclude list) after that it wants to backup whole disk no matter what. No such problem with 10.6.2 just with 10.6.3. Image so we are clear. I'm new to Mac OS X.
running OS X 10.5.6 on a macbook. I have been backing up using time machine to my Time Capsule, but would like to start backing up to a firewire drive. When I open up the Time Machine preferences and click change disk, nothing happens.
My IMac keeps freezing on time machine finding backup disk, it selects it fine and authenticates, the ready nas pro drive works fine other than this nothing shown in logs and firmware up to date, used to work fine.
