• Moving backups Time Machine - the operation cannot take place because the backup item is not editable

  I want to change the external hard drive that I use for my time machine backups. I went through the steps listed here:

  Time Machine: How to transfer backups from a current backup disk to a new backup drive - Apple Support

  It seems to work correctly. I shot TM back and adding the new drive. TM is now backing up files on the drive up, but there is a problem.

  For some reason, TM has begun to put backups "freely" for lack of better in the external hard drive, and not in the backups.backupdb folder for a week, then returned to save them in the backups.backupdb > ComputerName > files from backups. So in other words, when you click on the hard drive in the finder, it opens the player and you see a folder named Backups.backupdb and then a bunch of mixed in which files are backups time machine named 2016-01-24-XXXXXX, etc.. When you go to the folder Backups.backupdb, there's a more random "loose" time machine backup file 2016-01-23-XXXXXX, and then another folder with the name of computers and in the folder are all TM backups except loose ones I mentioned earlier.

  It seems that TM is working properly now, but I don't know why he put the files from the first days outside the backup folder. However, when I do drag, I get the error:

  The operation cannot be completed because backup items is not editable

  I want to just put all the files in the right folder so that I can A) keep my disk organized and (B) ensure what TM can find everything correctly should I have to go back.

  No idea what is happening and how to fix it?

  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."

• How to limit my Time Machine backup size?

  Hi, I have a 3 TB Time Capsule. My macbook uses all the 3 TB for backups. I would like to limit the size of the Time Machine backups to 1.5 TB and use the rest for my own files. Is there any setting or application in App Store to limit the size of the backups?

  Unfortunately no, if you ask on the backup using Time Machine.

  It is not officially supported by Apple, but you may be able to change the size of the space allowed for a backup by using this trick:

• time machine the ignored files

  One of my Time Machine backup disks is not back up all files on the drive that I copy. Ignored files are for the most part, the Photoshop files. Everything worked very well so far.

• Time Machine the new disk transfer has not moved all the time

  I have a Time Machine backup to an external drive. It works very well. However, he was beginning to run out of space, so I bought a new, bigger HD.

  I followed all the steps of Time Machine: how to transfer backups from a current backup disk to a new backup drive - Apple Support.

  I then waited 12 hours for that copy.

  Around midnight, I noticed the copy is complete. There was a message that iWork had not been copied because he needed a different operating system. But I rejected. There are no other messages.

  I changed the Time Machine preferences on the new disk. And fell asleep.

  This morning, I walked into a Time Machine.

  Only the first date from July 2014, was on the new disc of TM. Then there was five times after midnight when the new drive was saved.

  But there is nothing in any of the years between the first date and after midnight.

  I know that there are hundreds of TM captures on the original disc. And I've used them very well.

  I tried to copy individual files from the old drive to TM to the new, but it is not possible to "change the backups."

  Apple did not provide an easy way to recover from this condition. If you are not able to carry out these instructions, please someone more experienced to help you get. One option is to take an appointment 'Genius' on an Apple Store.

  Starts the Internet recovery mode by pressing the key combination command-option-R to start ringing. Release the keys when you see a spinning globe.

  Note: You need an Ethernet or Wi - Fi connection permanent Internet to use recovery. It will not work with modems USB or PPPoE, proxy servers or networks that require a certificate for authentication.

  In the OS X Utilities screen, select

  in the menu bar at the top of the screen, not one of the items in the OS X Utilities window.

  Follow the steps in this thread to ASC to split the fuser unit. The long string of letters, numbers and dashes you will need to enter will be different in your case. Copy and paste into the command in the Terminal window.

  This will remove all data from the fuser unit, then you had better be sure of your backups.

  Quit the Terminal, and then repair the Fusion drive (see "Troubleshooting" on the linked page.)

  Quit disk utility. Then you should be able to install OS X and restore your data from a backup in the main screen.

• Backups Time Machine very slow on 2015 MacBook Air

  Associated with a topic of discussion between a few days ago (two MacBooks, 10.11.4, a fast Time Machine backup and a very slow), I start a new topic with new information that seem to show it is a problem more general and not related to Time Machine networks.

  Here's the situation:

  • A 2015 MacBook Air, 10.11.4, 8 GB / 512 GB, has extremely slow performance of backup Time Machine, taking 40 hours for the first 300 GB backup and incremental backups for a long time as well
  • TM performance is essentially the same whether on the network (wired Ethernet) or a USB3 external disk
  • When you back up to disk USB3, I confirmed that the information system shows that the port is configured as USB3, not USB2 (nothing else is plugged into the USB port)
  • Tests of bandwidth I/O gross (using dd and iperf) show no problem; the network reached 110 MB/s bandwidth, written network managed at 50 Mbps, external USB3 HD written work at 40-50 MB/s (write hard drive speed limit)
  • 3 other Macs of various ages from 2009-2014 on the same network have no problem at all do backups Time Machine Network; a backup complete first on a 2011 MacBook Pro 500 GB takes 5 hours or more than 10 x faster than the MBA problem
  • Time machine network uses a Linux server running the latest Debian and Netatalk 3.1.8 and the connection is via a USB3/Gigabit adapter, no WiFi, and iperf tests with this arrangement shows 900 MB/s of throughput of the server.  In all cases, the Time Machine and external time Machine Network USB HD have the same symptoms.
  • The problem with MacBook Air is configured the same as the MacBook Pro 2011, which she replaced "daily driver", possible
  • This problem was shown by the MBA since his unboxing conversion, taking 20 hours for his first backup once Setup initially.  Incremental backups now take several hours, leading to interrupted incremental backups and, I believe, databases corrupted backup triggers new full backups that take today the 40 hours.

  Using Terminal Server and iostat, Console, etc, I see that there is significant activity e/s for the backup drive on the order of 20 to 40 MB/s for long periods on the MBA during the TM backup, but during that time the average declared backup size as shown in the window in the console and TM is growing by only 5 GB/hour.  This occur even if the backup will the external drive or a network drive. This seems to mean that the I/O bandwidth to and from the disk hard external, only 1/600 contributes to the progress of the backup.  I am sure that there is overload of certain checks and other tasks, but not to a 600-to-1 ratio.

  I tried to disable the limitation of the I/O of low priority as shown here: http://apple.stackexchange.com/questions/212537/time-machine-ridiculously-slow-a close-el-capitan-upgrade, that helps a bit (maybe 20-30%), but not by a factor of 10 for others.

  I have gone through a number of the Time Machine of Pondini troubleshooting steps, but he found nothing corresponding to these symptoms.

  The only thing I can conclude is that Time Machine, the application or configuration, on this specific MBA, is down. (A single thought that I wrote this to the top that I have not tried: the MBA and the time MBP running VMware Fusion and have a file of 50 + GB VM; on the MBA that is not excluded from TM backups while on the MBP is)

  Does anyone have advice on what to watch next?  In all cases, only one key would be why it seems that only 0.16% of all the bandwidth I/O to the backup drive seems to be actual data backup.

  Once again, three other Macs, all running the same 10.11.4, back to the Time Machine Server perfectly and have for years.  Only this new MBA glue as broken out, either to a network drive or an external hard drive USB3.

  (A single thought that I wrote this to the top that I have not tried: the MBA and the time MBP running VMware Fusion and have a file of 50 + GB VM; on the MBA that is not excluded from TM backups while on the MBP is)

  What happens when you exclude it as the MBP?

• direct AFP share vs time machine services

  I'm trying OSX Server 3.x (Mavericks), mainly to use it for Time Machine backups, but all her trying some of the other services as well installed.  My question is about the time service Machine that comes with os x Server.  I don't see myself using most of the other features on OSX Server, I will list out all my needs to the end server, but most of them can be easily made with different solutions open source, in some cases in a more flexible way, it seems then that means OSX Server out of the box.  But TM backups for my home network is the only thing that OSX Server provides I think is not provided in any other way, in addition to buying a Time Capsule.  Don't I have that right?

  Time Machine, the 1, 2 or 3 options:

  1. Buy a time Capsule.  To my knowledge, Time Capsule does not allow me to set a size limit for each client computer.  They are just fighting for space until the 3 TB drive fills up.  Also 3 TB is barely big enough (except USB).  With OSX Server I can throw in a disc of TM in there to manage several macs with big backup discs.  I also have an old mac alternative pro sitting here who need a goal.
  2. Run OSX Server.  check.
  3. Forget OSXServer, manually create a part of the AFP on mac server, create a sparsebundle to every customer mac that I intend to back up and since client mac, mount the sparsebundle and use it as reader of TM.

  So the question is: are there at - there any functional difference between Option2 Option3 technique?  TM OSX Server service a service works any extra well beyond the AFP, to make it more reliable in some way then option3?  If OSX Server provides just a comfortable GUI wrapper around the same underlying mechanism base mounting a sparsebundle via AFP, maybe do a little easier to monitor what is happening, etc...  Its nice to have if I happen to have OSX Server running, but if he is not so maybe I would be ok with option3 as his offering the same guarantees in terms of network dropouts, resource conflicts, and such things.  OSX Server makes it easier in some way or more reliable to stay mounted on the sparsebundle containing the tm, unlike option3 backup?

  Any thoughts?

  Also compare OSX Server to Time Capsule if you have knowledge.  OSX Server seems to bring some benefits... but I don't know if OSX Server just basically provides a way to configure the creation of the sparsebundle and I could just as easily do with hdiutil, even on a TC, but certainly in option3.

  Also, is there any additional functionality of TM put into play, if I configure Manager profile or something like that?  It comes to the essence of a single user in a network with multiple Macs, but a main user... it's not complicated.

  Beyond backup TM, I'll use this area for the following services, some of which may be dealt with by OSX Server and some cannot, or could be better managed by full versions open source:

  Time machine, AFP shares SMB sharing, Web, Pydio, Plex, iTunes server (maybe), FTP (pure-ftpd), postgres DB (need pydio or other uses I will come with), possibly git or necessarily crashplan finally.  I also can I possibly transition some critical documents of mission from a NAS separate mirrored on this machine using a raid mirror under OSX.

  Any thoughts welcome...

  Also following this question, does anyone know if its possible to have TM on the server machine, backup itself via the OSX Server TM service hosted on the same computer?  When I try to select a time backup device on the server machine, it does not display the optional service TM backup device, it shows that local hard drives that are available and stores the data in the normal way of local drive... not in a sparsebundle as do all other mac clients.  NOTE - I have service TM put TM backups on a separate drive internal then the boot drive... so it is always a good idea to make a TM on the same drive, so be it.  But it seems that I need a partition dedicated to isolate the backup of the server itself... or I need to use option3 and create manually a sparsebundle to save the boot drive, since he cannot see the time service machine OSX Server...   Don't I have that right?

• Time Machine NAS RAID

  Goal: large, reliable Time Machine back-up.

  (No purpose: archiving.) I do that separately on optical carriers per year, double copies, which goes off site. I understand that optical media can degenerate over time - even if some are marketed as "of archive-quality" - and therefore based on a cloud of archiving is the way to go but for now he takes too much bandwidth and I'm worried about security. I recently got a burner external blu - ray: exceptional.)

  Question: can I use RAID for Time Machine if I connect by USB directly on my computer?

  Issue 1: reliability external drive. This has happened twice that I bought a property, brand, large external hard drive and was prematurely fail at a difficult time. My local computer guru said "it happens" and is "unpredictable" and just buy a new one, most won't. Or, for better quality, get a NAS - network attached storage that can be attached, they have the temperature control, mine is a RAID 2 discs, so there is that the degree of redundancy - but not, I learn, protect against a corrupt Time Machine backup and that can happen, or power increases (although it is on a high-tech power bar) , or theft, etc.

  Problem 2: using NAS, which I connected to a Terminal Airport Express via an Ethernet cable - if connected to the computer by WiFi - the Time Machine backup becomes a "sparsebundle" (set of files, in fact), encrypted file with password (?) drive access. However, this was work and I did a full restore of your data (no 'system') the other day with Migration Wizard when I got a new hard drive installed in my old iMac (also upgraded at the time of 10.9 to 10.11). It took over all night, but the wonder of wonders, it chugged along and finished and seems fine. (I have not checked tens of thousands of files individually!)

  (My SIN explicitly supports Time Machine, and I checked that box in the configuration of the SIN, and it seemed to work.) I didn't have to leave the mounted drive. Time Machine found hourly and used invisibly in the background.)

  Problem 3: I have rename my hard drives for some reason any and do not remember quite what its name was. I wonder if this is part of my problem (read more). But there is a method in Time Machine to 'Browse other discs of backup. " I was looking for a file that I kept outside my usual login "user" and so had not been returned when I used Migration Assistant for data recovery only.

  However, when I do this, then nothing is there. I've learned that sometimes, with an encrypted sparsebundle, wireless backup, you will have to let Time Machine sit for a few minutes before the back-ups start to appear, but now, with my new hard drive (with a new name) and the new version of the OS, there is simply nothing; just 'today' that shows only my current hard drive status. Obviously, there was something, or Migration Assistant wouldn't have worked, but during the inspection of the backup via Time Machine, the file seems to be here (whatever_my_computer - name_was.sparsebundle), but it is empty.

  If I just try to navigate in the Finder to the sparsebundle NAS Time Machine, I can find it but not to open it. Double click: nothing happens. It is not that I forgot to connection settings, this is what it do not ask me for them.

  This happened to me twice and the first time was the day after archiving (luck and good planning) and I thought that it is a kind suddenly lucky, but now it happened again.

  So, I tried a bit of searching and not found a clear answer to my question above. I do not see these links:

  TEM http://www.petemarovichimages.com/2013/11/24/Never-use-a-RAID-As-Your-Backup-sys.

  https://support.Apple.com/en-CA/HT201250

  https://discussions.Apple.com/thread/3837784?start=0 & tstart = 0

  https://discussions.Apple.com/thread/7448896?start=0 & tstart = 0

  https://discussions.Apple.com/thread/5849068?TSTART=0

  Of them, it seems that a NAS that has an explicit ability to Time Machine might work (mine did), but is not fully functional, not approved by Apple and is completely unpredictable. My limits are described above. (I work around them).

  However, moving forward: I have this RAID 2 discs sitting around, seemingly more reliable than a drive external non-temperature controlled, and I wonder about the connection by USB directly on my computer. What is the downside of this? That is my question. Who will 'normally' work as a Time Machine backup external drive?

  Another option is to get two large external hard drives and the value of Time Machine to switch between the two. I have not tried, but apparently it was possible for the last iterations little Mac OS X.

  I have important data that requires careful management.

  Thank you all,

  Charles

  I use a direct attached Drobo (it is a very easy to use RAID device).

  I've always had problems with Time Machine on the network, so I stopped using it in this way. I've never had problems with the TimeMachine and direct-attached storage.

  With the Drobo if a disk goes bad, I buy a replacement and hot it swap for the failed drive.

• Impossible to 'create' Time Machine backup service

  I have Mac OS x Server v 5.1.7 running on a Mac mini (2.7 Ghz core i7, 8 GB RAM, mid-2011)) with OSX El Captain (10.11.6).

  When I try to add a folder to use as the destination for my backups Time Machine, the button 'create' on the next screen does nothing!

  

  How can I diagnose what is the error (if any?) and how can I work around this?

  OK, I've been searching and I found everything about TIME MACHINE on these forums, but my question is still not answered.  My suspicion for why my attempt is a failure is due to the fact that the drive mounted by the mac mini is formatted with NTFS and mounted using Tuxera NTFS for Mac. How can I confirm this? If it is true, is it documented for OSX Server Anywhere? Why is there not an error message or something to help me?

• Recover mail - Time Machine dates in gray

  Following a successful by Apple repair, my MacBook Pro with El Capitan is now rebuilt and everything works, including mail.

  I used to have a number of files that I used to store mail offline (family, finance, service provider, leisure, etc.)

  I have a Time Machine disk that contains data. I tried to recover by holding the Option key and selecting the right disc, but I can not go far enough - he reached on a date with a red line against it on the right side in Time Machine, but all the above dates that are grayed out (page are in gray), although I can see the date. Clicking on it does nothing.

  The disk in the Finder, I can see the files throughout the library > Mail > V2 > mailboxes > {various .mbox files}

  Given that I can see / copy, is there any way I can get them in office on the MBP please?

  Thank you

  Bob

  In Time machine the last date that is not grayed out: go to the folder 'up', the one you are in, may be still another level above, then go further back in time. then go 'down' in the folder and again until you find the records you are looking for.
