• 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?

• My computer turns on once a week automatically during the night. How can I stop this from happening? Thanks Gunter

  Hello
  I bought a used desktop computer. After setting it up again to what I had before I find the computer comes on every Saturday night at the same time. How can I stop this from happening?
  If anyone has an answer for me please give him in singles and not "computer language".
  Thank you
  Gunter

  Your best course of action would be to do a complete new installation of Windows.  Not sure how this computer has been maintained or used.  She could have anything whatsoever thereon against malware of illegal material.

  Although the automatic turn on every Saturday night is probably trivial (for example, some application checking to see if there are updates), it could be malware "phone home" with your personal information (bank accounts, passwords, etc.).

  This TechNet article provided by 'Support' engineer is not likely to be useful for you.  For Windows XP (you posted your question in a Windows XP forum), open scheduled as follows:

  Click Start > click on all programs > point to Accessories > tap System Tools > and then click scheduled tasks.

  Review each of the tasks listed to determine what they are doing.  You can then decide if you want to remove one of them.  You should consider, however, that there may be other mechanisms that cause your computer turn on as you describe.

  I have Photoshop CS5.1 on my Mac now and you want to transfer to my Mac Book Air newly purchased. How can I do?

  Just install it like you did the first time (do not try to transfer from the old machine somehow) - you can download it through your account if you bought for download originally - otherwise, there is a link to download below. Your serial number should be available through your so into account your registered Adobe software previously.

  If you want, you can leave it on the first machine as a backup because you are allowed to have two active facilities.  If you want to remove from the older machine you should first turn it off (open an application and choose Help-> Deactivate).

• When I open a link that opens a new Firefox window, it opens 2 tabs instead of one. How can I stop this?

  When I open a link that opens a new Firefox window, it opens 2 tabs instead of one. A tab is the link that I opened and the second tab is just a generic Mozilla tab with links to 12 pages like Facebook, Youtube, etc. This tab opens on top too, so I always have to close to get what I'm looking for. How can I stop this from happening?

  Hello. Thanks for all the posts on this topic. I have the same problem, as described by the op. But, while I use Avast, I have NOT the add-on from Astromenda which has been mentioned. However, I have the SB installed toolbar, and it has been recently updated, 29/12. I suspect that it is the culprit, if this problem is in fact not caused by an update of Firefox (my tiles have recently been reset on new tabs, and I suspect that Firefox for this problem).

  I am ready to remove the toolbar from the SB, but prefer to keep it (Yes, I admit I'm stupid) If this annoying 'new window = 2 tabs with 'new tab' at the top' would just leave.

  Apart from the removal of the toolbar SB... does anyone have suggestions? I don't see that all recently added add-ons/extensions that I don't recognize, apart from the update of the toolbar of SB.

  Updated: 5 minutes after this announcement, I disabled the toolbar of SB and restarted Firefox. No change.
