  • If time machine is incremental how it removes previous versions when the disk is full, without breaking the chain, so do not be able to restore all changes since the first full file

    If time machine is incremental how it removes previous versions when the disk is full, without breaking the chain, so do not be able to restore the file with any changes made since the full backup first file...

    If the TM drive storage is full TM automatically deletes the version the oldest files for the new incremental backups can be made. Thus, in this case you cannot restore the versions that TM deleted because it takes more storage.

  • Can I do a differential restore from Time Machine?

    I have a user who has a file structure that lists many companies, each company has its own folder, and inside each folder there is a file called "Notes.docx. This means that each company has a generic file called notes:

    Companies folder

    File of the company 1

    Notes.docx

    Business account 2

    Notes.docx

    File of the company 3

    Notes.docx

    I've already made conscious, that this is a bad idea because it can identify files specific notes difficult, however this isn't the problem.

    The problem is that there are hundreds of records of the company , and it appears that many files of notes are missing at random. I don't understand not what causes some of them should be deleted, but not all, but that's where we are. To further complicate the issue, that he did not have a Time Machine backup since 3 months ago, so simply rolling the MBP back is not an option. Currently she does is he finds a company that does not contain the file notes that it connects to the time Machine and restores a single file.

    Of course the way he does now is not very effective and will take considerable time. I'm looking for is an option that would make a differential comparison on its records of the society and those who lack the file notes , unroll the previous version of time Capsule. Is this possible? I'm also open to other suggestions, thank you all!

    Time Machine can do in one shot... If you retrieve a directory on the existing directory... Yes, I think it will be...

    Be smart... Copy the directory to a new location existing.

    Then do a restore of this directory of backup TM in the same place... let run and then check the results. Look particularly for situations where known files could be early version on the last copy.

    Moreover,.

    I could do this in two steps.

    1 retrieve the entire repertoire... without doubt, all the records of the company are in the folder documents or something on his computer.

    You can go to TM and retrieve the directory to another location.

    2 copy the directory from the original. Be smart of course use a copy of terminal as rsync command. Just look to the top of the rsync command... you don't need to be pushed eggs... but being smart of course... do not do without a trial on the copy of its directory with all the files of the company first to make sure it isn't wasting. I just googled for rsync command to file update from the source to the target.

    rsync - v h - r Pei t source target

    This transfers only new files and files already existing but put to update the:

    The parameters in detail:

    • -h: numbers readable human
    • -v: talker
    • -r: recurse into directories
    • -P: --partial (keep partially transferred files) +.
      --progress(show progress during transfer)
    • -t: preserve modification times
  • Time machine does not see the existing backups

    When I tried to make a backup of TM to my doesn.t TM HD external see my existing backups and trying to do a new backup complete. Firstly, it said "preparing backup..." "that takes a long time before you go make a new backup full not not using the existing to make a differential.

    You're talking about two different things that above:

    • Create a new full backup
    • Recognizing the existence of previous backups

    You seem to be assuming that because Time Machine seems to be to create a new full backup, so should not recognize the existence of all the previous backups.  This assumption is wrong.  New full backups are created, for example, when the update of OS X.

    The way to check if the Time Machine recognizes the previous backups would be to use the Time Machine application to check if you can see previous versions of files.

  • Time Machine-to the exclusion of directories

    I'm backup my iMac SSD drive (500 GB) on a 3T OSX to format drive.  I also use a directory on this 3T USB as a secondary drive in my favorites (Finder).  What I find is that Time Machine takes about 3-4 DAYS to run a backup.  It takes a particularly long time to complete the process of 'cleaning up' after the backup (which apparently does not get completed if broken.)

    When I "Get Info" to the Backups.backupdg directory that it takes several hours to calculate the size of this folder (~1.5T), while "Get Info" is almost instantaneous on other 4 or 5 t formatted (NTSC) or another OS x 2 t formatted the disk.

    I do this so I can backup the entire disk 3T a cloud or off site backup.

    If I can exclude the Time Machine backup of itself, I suspect the backup can be done in less than an hour. Is there a way to do this in Time Machine or must it backs up the entire drive?  If the latter, I'll apply for improvement for Time Machine!

    That confuses me. Time Machine is unable to save himself.

    I also use a directory on this 3T USB as a secondary drive in my favorites (Finder).

    If you back up the content that is stored on the backup volume, Time Machine will not work properly.

    I think there is something on your Time Machine configuration, I don't understand. Even if your iMac contained 500 GB of content source, the initial backup to a drive connected locally can take a few hours. Subsequent incremental (hours) will take only a few minutes.

    How this backup disk is connected? USB, FireWire, Thunderbolt...?

  • adding the 2nd Time Machine disk backup capability

    I have a Mac pro OS X 10.11.5 with two discs devoted to the backup. When I wanted the first filled to the top, then add the second to continue archiving backup files.

    I don't want to lose my older archived data in backups on disk 1.

    What happens when I add a second drive to add capacity to the Time Machine backups?  Once the first drive is hard full TM then will use the second drive until it is full?

    When you add the second drive, I get a warning that the TM will take turns using the disc 1 and disc 2. But 1 disk is full. TM will not delete old information on Drive 1 to make room? If Yes is not good because I want to keep the old data. I just want to keep incremental backups to Drive 2.

    Please specify the feature.

    Yes, TM will continue to save on disk 1 and delete older backups and take turns with disk 2. If you want to keep 1 as it is by car, then you must remove it from the list of backup. Start a new backup on disk 2, and continue. In both cases, the disc 2 will make a new full backup of your computer.

  • Time Machine does not register the last backups

    In Time Machine preferences, it signals that the last backup is June 2, but when I go to Time Machine I don't see what

    which seems to be backups in recent days.  How do both to sync to declare the same data?

    • Assuming that your profile information is correct, OS X update to the latest version: How can I update to OS X and Mac apps - Apple Support.
    • If you do not already done, simply connect / again or restart your Mac.
    • If you back up the contents of the source that lies in the external devices, make sure they are all operational, mounted and available.
    • If the last time information and the date are still incorrect, continue with the steps below.
    1. Confirm that a backup is not already underway. Then, scroll down to 'Add or remove backup disk... '. "and select it. Choose 'Data' and then delete.
      • If everything works as it should, this will not affect your existing backup history. However, if you have done this until now it is not working as it should, and in an abundance of caution you should consider creating an additional, redundant backup first. If you work with the data that you just can't live without, that a backup is not enough in any case, even if everything works perfectly.
    2. Then select the drive again, connect you and choose 'Back Up Now' in the Time Machine menu bar icon.
      • If you have added previously any exclusion of the element (under the 'Options... button "), you will need to add.
    3. Time Machine will take a lot of time while it makes a 'deep event' scan to determine which files need to be backed up. Meanwhile "preparing backup...". ' appears in Time Machine preferences.
    4. When the "scan deep event" is over, Time Machine will perform a normal incremental backup, which will have the usual amount of time.

    That should correct the erroneous information.

  • How to force a backup complete in Time Machine?

    How can I force a new full backup in time machine? My iMac has Time Machine installed and used for 2 years. He is 2 years old and more incremental backups but I'm about to upgrade to OS X 10.8.5 OS X 10.11.5 and instructions say back up prior to installation.

    Should I force a new full backup?

    Completely erase your backup by using disk utility disk (for a Time Capsule use Airport utility.) Time Machine will automatically start a new backup.

  • Why is backup time machine so slow?

    Is this the first full backup or incremental backups?

    The first backup takes a long time.

  • Copy the old Time Machine files to the new disk TM

    Sorry people, I have to ask two (related) questions:

    (1) I have a WD My Passport for Mac drive connected to an Airport Extreme and 2 Macs use for backup via Time Machine. Now, the disk is full. I bought a WD My Book for Mac drive with a capacity of 4 TB and am ready to go.

    Question: can I copy the old files of Time Machine on my new book?

    (2) until now 2 different Macs used the My Passport as a Time Machine drive with no problems.

    Question: Should I partition the new drive (My Book) and every Mac uses its own partition as Time Machine or can proceed us as is?

    Thank you very much for your help!

    Question: can I copy the old files of Time Machine on my new book?

    Yes you can, but there is a lot of work, a little complicated, time consuming and not worth the effort for most users.  The main reasons for this are...

    (1) the older backups will take a good amount of space on the new drive, limiting the space on the disk again.

    (2) Time Machine backups for the old files will continue... it will make a new copy of every Mac and then go forward again with incremental backups.

    A better plan would be to keep the old drive on hand for a few months, in which case you need to go back and look for a file. After a few months, you will have a beautiful story from backup to the new hard drive and no need of older backups so you can remove the old disk and keep around as a spare part or use it for other purposes.

    Question: Should I partition the new drive (My Book) and every Mac uses its own partition as Time Machine or can proceed us as is?

    While you can partition the drive and save each Mac to a separate partition if you wish, there is really no need to do this since Time Machine will automatically create separate for each Mac backup files.

  • Is there an advantage to having a backup disk image of Macintosh HD (for MacBook Pro) to ease/speed of recovery after a disk failure rather than using Time Machine to recover?

    I'm trying to understand the best way to prepare for the recovery of a failure in the drive for a MacBook Pro.

    I do not understand the nuances of the time Machine - I know from personal experience that it is a recovery tool great when your existing drive is intact and you're just trying to restore a file.  But what happens if the drive has a hardware failure and needs to be replaced?

    Is there an advantage to take periodic images of Macintosh HD for quick recovery (and then using the incremental backups Time Machine to catch up to the current position).  Or Time Machine may facilitate a recovery in case of failure of the disc just as easily/quickly that will give it to have a separate image backup?

    Thanks in advance for your help.

    YES!.  If you have a clone boot disk, you can either connect it to a MBP or Exchange it with the internal HDD failed and be back in business quickly.  Time machine, as good as is, can take several hours to restore your system, depending on the amount of data.

    For cloning, I recommend Carbon Copy Cloner.  It is not free, but it's worth the price:

    I use it in conjunction with Time Machine.  (two backups are better than one)

  • 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?

  • I'm using Time Machine (1 TB), works very well, but because full starting to delete previous backups. Can I add another (LaCie 1 TB) HARD disk for backups? If so, how to proceed. Thank you!

    I'm using Time Machine (1 TB), works very well, but because full starting to delete previous backups. Can I add another (LaCie 1 TB) HARD disk for backups? If so, how to proceed. Thank you!

    You can add another drive to accept backups Time Machine... assuming it is correctly formatted for Mac to Mac OS extended (journaled), but things are not exactly "continue."

    You have not indicated if you intend to add the player to the USB port on the Time Capsule, or connect directly to your computer using USB or FireWire connections. Or the other method works, with the option to connect directly to the computer being the faster connection.

    Once the disc is added, you would go in Time Machine preferences (click the "clock" at the top of the screen on your Mac) to add the disk for Time Machine backups and delete the old Time Capsule disk, since backups will go is no longer this destination.

    Since you have a new drive, Time Machine will do a new full backup of your Mac and then go forward with incremental backups.

  • Two MacBooks, 10.11.4, a fast Time Machine backup and a very slow

    In our office at home, connected to a Gigabit ethernet on the same switch network, we have two MacBooks.  One is a 2011 MBP with a 1 TB SSD (third party), and is an MBA in 2015 with a 512 GB SSD (Apple).  A Linux server on the same network running Netatalk 3 providing the backup network drives, one for each laptop. The two TImeMachine network drives are on the same physical server drive.  Two laptops running 10.11.4 and darn are configured almost identically.  Neither laptop has no trouble finding the network backup drives, and they begin to run backups without problem.

    The old MBP was a workaholic and functioning flawlessly for years, including the fast and regular Time Machine backups. File unique restorations are done with some regularity, and they always worked (I don't think that once done, we use a complete restore of the system from scratch, and it worked).

    The new MBA, in contrast, had endless questions from and complementing the backups.  Last night, for example, I decided to simply reformat the drive on the server where there is a material error affecting the MBA (I ran Linux fsck to check the file system before you wipe it off and he's found no errors) and resumed full backups on two laptops.  The MBP has about 600 GB for the first backup, and complete the backup in about 5 hours.

    MBA, with about 350 Go back up, was still underway this morning and had less than half the backup is finished. In the console log, he showed he was backing about 5 GB/hour.  Not only that, but the incremental backups took a lot of hours (more than overnight), making it impossible to never complete because it must be packed and taken to work at some point in the morning.  I.e. backups are all simple broken on this MBA.

    The MBA connects to the network with a third USB3 (Anker) hub that has a Gigabit Ethernet port on this subject.  I downloaded iperf for Mac and Linux server and found that this is right about 900 Mbps throughput, so I expect an optimal bandwidth is achieved in this regard.

    Any ideas what might be happening here?  Diagnosis between the two to see what could be such a radical difference? Tried to change taps the network wiring/switch problems, without change. Reset, no change.

    We have two other Macs also running backups in this way, under 10.11.4,, and they were also without problem. Also is it just that an MBA, the most recent of the bunch, problems.

    A third-party file server 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 developer 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 problems that result is for the developer (who will blame Apple, neither you nor anyone else but herself.)

  • Backups Time Machine huge after importing the photos

    Hello world

    I noticed that whenever I have import pictures (usually about 3-5 with a few MB each, taken with my iPhone 5 s) the next time tracks TM backs up a huge 50 + GB. I thought that TM would be smart enough to detect only changes in the bundle of photo library? My library is currently 138 GB in size, so whenever I have add a few new images TM is save half of this new.

    What are your experiences?

    Thank you

    Björn

    When you make changes to the content of Photos, is not only a few additions that change, but also databases which keeps the pictures. TM stores incremental changes.

    Personally, I don't bother watching over Time Machine. He seems to know what to do without my supervision
