• Time Machine backup fails because "there is not enough space on the «DiskStation «»

  My backups regular TimeMachine to DiskStation stopped working a few months ago.  I thought it was because I ran out of space but now I installed an extra 1 TB RAID and I always get this error message.

  Here is the chronology of events that led to the error message.

  16/01/10 23:09 - Backup started manually (1.47 TB TB 2.45 available):

  

  16/01/10 23:11 - preparation of backup... (1.47 TB TB 2.45 available)

  16/01/10 23:15 - "backup: zero KB of 63.8 MB, calculating time remaining..." »

  16/01/10 23:22-2.1 MB saved 63.8 and the first estimate of the remaining time: 'about 4 hrs.

  

  16/01/10 23:50 - now 2.3 63.8 MB MB, 16 hours left (I'm ready for bed).

  16/01/10 23:55-5 minutes later and it backed up 419 MB!

  16/01/11 00:55 - an hour later and it is up to 6.72 GB but the gas target increased to 7.39 GB (I went to bed)

  16/01/11 06:50 - next day morning and it's up to 23,76 GB and the goal is now to 26.13 GB

  

  16/01/11 18:49 - I go home at night and it failed.

  

  

  

  Here is the view viewfinder of the TimeMachine file that I am trying to backup (note, a lot of disk space):

  

  This is the view of the Inspector of it:

  

  System details:

  -MacBook Pro 2013 with OS X 10.11.2

  -LAN WiFi Pace 2Wire998 router with DiskStation connected by Ethernet, MacBook Pro by WiFi

  -Synology DiskStation DS411slim with 4 x 2.5 "hard drives installed.

  A device third-party network attached storage (NAS) or a router is unsuitable for use with Time Machine, especially if it's your only backup. I know that's not what you want to hear. I know that Time Machine accepts the device as a backup destination. I know that the manufacturer says the device will work with Time Machine, and I also know that it usually seems to work. Except when you are trying to restore and find that you can't.

  Apple has published a specification for network devices that works with Time Machine. No third party provider, AFAIK, does meet this specification. They all use the application of Netatalk incomplete, obsolete Apple Filing Protocol.

  Apple does not endorse any device third-party network for use with Time Machine. See this support article.

  Network backup, use as destination an Apple Time Capsule or an external storage device connected to another Mac or a 802.11ac AirPort base station. Only 802.11ac base stations support time Machine, not older model.

  Otherwise, use Time Machine at all. There are other ways to save, although none of them are nowhere near as effective or as well integrated with OS X. I don't have a specific recommendation.

  If you are determined to continue to use the device with Time Machine, your only remedy for any resulting problem is the manufacturer (who will blame Apple, neither you nor anyone else but herself.)

• Time Machine backups fail

  I have a Time Capsule 2 TB 4th generation bracket place my 2013 21.5 in iMac running OS 10.11.3. For the two weeks have been a failure my time machine backups. A few nights ago, I was given the opportunity to create a new backup, which I tried to do. However, the new back-up has never been created - says still 'wait to first full backup"status on the menu bar. I am able to access the files on the Time Capsule that aren't in a backup file Time Machine and use Time Capsule as a router. When I enter the Time Machine on the iMac, it appears as if it has never been a comeback upward (which, of course, I guess). I tried to use the repair disk utility - I had to run on the Time Capsule, but it did not help.

  Any thoughts? Thanks in advance!

  Looks like you receive a message that a few nights under what looked like this:

  

  It is probably the most frightening message that you never see when you use Time Machine, because it shows that your backups were corrupt. Time Machine will try to erase, and then create a new backup.  Unfortunately, sometimes Time Machine fails when it tries to do.

  The best thing you can do right now is to perform a deletion process of resetting the data on the Time Capsule disk to completely erase the disk for errors and try again another backup.  If you decide to try this, you must copy all other files you might have on the time Capsule to another disk for temporary storage... unless you already have other copies (you should, otherwise, you have no backups for files on the Time Capsule).

  Perform the zero... erase data, which will be probably 3-5 hours or so... should improve your chances of a good Time Machine backup when you restart the process... IF... the last problems were the result of software on the Time Capsule disk errors.

  IF... the time Capsule hard drive is physically damaged... which is a possibility... you need to replace the disk in the time Capsule hope forward again.

• Cannot delete the Time Machine backups

  I have a MacBook Air and a 128 GB USB key that holds my library of photos, so I always make backups. My system - and I have recently made account how flawed it was - was to create backups on a 500 GB HARD drive, but to transfer them to a 2 TB HARD drive when it is full. So, I finally discovered that when I transfer backups in small quantities to the 2 TB, it takes more space because instead of aliases of files used to represent more recent backups, care of file just copied over and over again. For this reason, I put my 2 TB as a feature of time machine and imported all the old backups in the folder backups.db, that my Mac 'cleaned' and registered 135 GB. But 135 GB is not enough, I went and delete backups that I don't have anymore. When I looked in the trash to empty, I've seen 2 things: backups I have trashed and others who are pale sort out. I can't open the files, even if I right click and select "open in a new tab. When I try to "immediately remove" these paled-out files, I always get a message that they are "on duty." It is about 300 GB, so I must get rid of him. But it does not stop there, because when I try to "delete immediately" backups I had trashed myself, I get an error message! It is a total of about 600 GB, what I absolutely need to get rid of! If anyone has some tips, it will be greatly appeciated.

  You have probably sprayed your Time Machine backup database. The best thing to do is erase the disc with Airport utility. Then start again with a new backup.

  Good day.

• Remove the Time Machine backups in a certain amount of time

  I have an iMac in the House which is not backup because I have just updated to El Capitan, then now it says that the time Machine doesn't have enough space for a new backup (no doubt because my 200 + GB photo library moved to the new application Photos). Therefore, I need to get rid of some my time Machine backup. My MacBook Pro has almost 1 TB of backup files and I want to delete some, but I don't want to delete ALL my files backup, just in case I need something from him. Is it possible to delete the backups in a certain interval of time quickly, in order to keep all my backups and delete the 'old'? I know that you can delete the backups one by one, but the first backup of my MacBook was in 2014, and I don't want to have to go through 100 backups one by one to manually remove all the...

  Time machine records differences, so delete a backup may stop all your backups made subsequently. Here are some tips on how do it safely for ti:

• Transfer Time Machine backup on the new disk, preparing already > 24 hours!

  I followed the instructions on the web site (Time Machine: how to transfer backups from a current backup disk to a new backup drive - Apple Support -essentially a copy via the Finder) and after more than 24 hours the copy process is still "preparing to copy" and lists currently more than 4 million items.

  Yes, I have a large number of files, 2.65 TB of info I want to spend on a new disc of 6 TB, but this method of copy will take too long. I'm afraid I have to stop the process of copying in the morning, because I have to take my MBP on the road.

  Is there another "clever way" of making a Time Machine backup on a new external drive?

  You can try using the software clone to make a copy, but I'm afraid that the size of the data you are trying to copy will take a long time with any method.

  I suggest starting with a new Time Machine backup disk 6 to and leave the old time in the form of a Machine archive to use if necessary.

• Cannot transfer Time Machine backups on the new drive

  I store my backup Time Machine on a Seagate 1.5 TB drive when the drive starts giving errors.  I had files on this computer and was able to transfer all except for 2 who were on unreadable sectors.  Fortunately, one of these files was an older archived version that I could afford to give up and the other was a temporary file in the photo library and since all other items were okay, I think I'm good.

  The problem came when I tried to transfer my Time Machine backup of 800 GB for a new disk.  When I copy and Exact-paste (cmd-opt-shift-v) the Backups.backupdb to the new drive, it gets the extent of November 23, 2015 and then dies because reports of the Console to the system, it gets an IO error when you try to read:

  /Library/SystemMigration/history/migration-245250B6-4F52-4FBB-BD61-546A8C19CCD5/ QuarantineRoot/private/var/db/dyld/dyld_shared_cache_x86_64

  in the relevant backup.  And because it's an IO error it simply abandons the whole process so I have no backup from November 23, included, for now.

  Because the disc is unstable, I wasn't able to use disk utility to make repairs on it.  The disc is what is and I have to deal with the mess, that I do not have the disorder, that I would have.

  I tried to manually place the missing files in the database, but the operating system will not let me.  I want to just copy my backup / OS X stop abandonment and be more like Windows and give me the options to "try again" or "fail" instead of just quitting!  I mean, why should I lose my backup all hierarchy of 23 November and beyond, simply because you cannot read a file, a file that I could simply replace in the backup of the current version or you can just ignore it.

  I tried to copy files on and setting xattr on them to be backup items, but they are wrong.  I tried chflags parameter to make the writable directory, but it does not work.  I can't copy the missing files to fix my archives.  Help.

  Please, don't try to transfer backups of a failed drive. Placing the disk aside until you don't know no longer you need the data, then delete and recycle. Start a new backup set on the new drive. For more security, you always have more than one backup.

• Time Machine backup to external drive connected to the TimeCapsule

  I have a 3 TB TimeCapsule, that contains the my iMac TimeMachine backup. So far so good.

  Now, I would like to connect an external drive to the TimeCapsule via the USB port to allow access to this drive of my iMac as well as other computers on my network. I would like to than the external to include in my Time Machine backup drive. Is it possible - by accepting that the backup of obviously only runs when the Mac is on? If this isn't the case, other methods of backup to an external drive, connected to the TimeCapsule, may be recommended?

  You can do it. Time Machine it will support up to a separate folder on your backup disk. Don't forget to remove it from the exclusions list in Time Machine preferences. I don't know if others cannot see the drive connected to your computer is turned off. They may be able to mount the drive on their computer as you do on yours. Try it because I could be wrong on this matter.

• How to transfer Time Machine backup to the new external hard drive

  I'm upgrading to a 1 hard external to the Western reader to with 5 TB of Seagate.  This is because Time Machine has used the 1 TB drive.  How can I transfer the files from backup Time Machine from the old to the new drive so that backups continue to have access to the old files.

  Although the documentation Apple says you can copy Time Machine backups in the Finder, it is very slow and sometimes does not.

  This technique works only if the volume that you copy to the same size or larger that that you are copying to.

  First of all, please open the Time Machine preference pane and click the Select Disk... button. You may be able to unlock the settings first, by clicking on the padlock icon in the lower left corner of the window. Log in as administrator.

  Remove the volume you want to copy in the list of backup destinations. Then turn off Time Machine.

  Launch disk utility, open the built-in Help and search for the term 'Double '. Follow the instructions. All existing data on the destination volume will be deleted. That shouldn't be a problem, because you do not want to mix non-sauvegarde and backup data on the same drive anyway.

  If the volume you are copying has been encrypted by Time Machine, you must first unlock it. Click the release button in the toolbar of the disk utility window.

  Turn Time Machine back on and select the new volume as a backup destination. Alternatively, you can continue to use the old volume, if you wish. Both will be alternated when both are available.

  ATTENTION: If you copy the volume is corrupted, as shown by the ERD or first aid in disk utility, while corruption is copied to the new drive. Do not copy data from a damaged on a faulty disk volume. Put aside the reader and do not use until you don't know that you no longer need the data. Then securely erase it and bring it to a recycling center. Do the same if the restore operation fails with "disk errors."

• Corruption of the spotlight for a time Machine backup

  My time Maxhine back up not ended. I realized that I got and I canceled the back upward.

  I used my second disc for the back and finished. When I went about this Mac it was completely blue. I reindexed my hard drive. While the result is not perfect, it is now. And I saved since.  My concern now is:

  1. are my ups back corrupt and if so it ruins so any chance of

  2. a successful restore, time machine? Because it looks like my hard drive needs to replace.

  Thank you

  Try to use the Time Machine application to see if the backup is loading properly. If so, your backups should be good. You can also go into the Time Machine menu, while holding down the option/alt key and select verify backups. For more information of reset, see A4 & A5 in the first linked article.

• Door key lost in the time machine backup

  Dear community,

  Because I had trouble with the speed of my MacBook Pro (and nothing else developed), I had to set up entirely new.

  Before installing El Capitan, my MacBook Pro (starting 2011) ran on Yosemite 10.10.5. I made two backups with time machine, generated a bootable El Capitan installation USB key, in format Macintosh HD, installed at El Capitan and ran all the updates. The system works well, everything works perfectly and my Mac is fast again. Now, I manually copy things that I need in my system of charges.

  Here, the problem is: I can't find the old keychain file in the time machine backup!

  Keychain works with the keys stored in iCloud. However, the other buttons are gone.

  As I discovered, ~/Library/Keychains is hidden. I did it visible on my system running. However, this does not work in the backup file. It remains hidden or - worse - have not been stored in the backup. I don't know that I have excluded from time machine backup only two totally different folders (dropbox and movies).

  You have any ideas how I can find my keychain (login.keychain if my search was right) in the time machine backup?

  Thanks a lot for your help!

  Time Machine, please press the shift-command-C key combination. The windshield will show the mounted volumes. All snapshots should now be accessible. Select the one you want and search for files to restore.

  If you need to restore from a backup of the hidden user library folder, first select a snapshot, and then press shift-command-G. A go to the folder dialog box opens. In this document, you enter the path to the folder. The dialog box will help you by automatically filling parts of the path when you start typing.

  The path starts with the slash character ("/"). Enter that. The rest of the parts is separated by slashes.

  The next part is the date and time of the current snapshot. Enter a '2', and the rest of the date should be filled in automatically. Press the right arrow key to access the end of the path. Enter a slash to start the next game.

  Next is the volume name (usually "Macintosh HD" unless you assigned a different name.) Start typing, then jump to the end and enter a slash.

  The next part is 'Users', followed by a slash.

  Then is your short user name. It is also the name of your home folder, which is represented by an icon of the House in the sidebar of a Finder window.

  Finally, enter "Library", and then press return. You should now be in the library folder. From there, you can move like in the Finder. You can also select another snapshot of the same folder.

• 'Time Machine' backups on disk could not be ejected because it uses "Photoshop".

  Almost daily when I try to eject my disk Time Machine, I'm greeted by "the drive 'Backups Time Machine' could not be ejected because it uses"Photoshop"." It's super annoying.

  

  We try to fix it.  But, again, it is a more serious problem that can be fixed in a dot release. (really, that's all I can say)

• macOS Sierra stuck on the Time Machine backup

  Its been 2 weeks now since I updated to macOS Sierra and my Time Machine backup is always stuck on "preparing backup" and I tried different disc backup on another partition but still no luck.

  Make sure that:

  o drive the TM is excluded from Spotlight indexing non-mandatory;

  o that all software anti-virus is disabled (especially Sophos);

  o journal of iCloud and other cloud services.

  o check this article: macOS Sierra: If Time Machine still at the stage of "preparation"

• Time Machine - there was an error preparing the Time Machine backup drive (could not mount the drive)

  I have a new HD but cannot set up encryption with system preferences. After ten minutes, I get the following error message:

  "There was an error preparing the Time Machine backup disk (disc name) - could not mount drive"

  Apparently, I need to set up the HD in this way:

  • If you are using an external drive connected to your Mac, use disk utility to make sure that your backup disk is formatted in HFS + extended (journaled) and is the partition type GUID Partition Table (GPT)

  It is not an option for the HFS + and so I used; OS x EXTENDED (journaled). GUID is ok.

  Can someone let me know what I need to do.

  Thank you

  Formatting: GUID Partition Table, OS X Extended (journaled).    (it is HFS +)

  For TimeMachine at best to a partition only.

  Do it again if necessary, then disconnect, reconnect, Start Time Machine preferences and "select disk".
