Time machine mac too slow

Another trick to remedy sluggish Time Machine backups involves booting the Mac into Safe Mode , then rebooting the Mac back into regular OS X mode, and starting the backup again:. This is a bit of a weird solution to abnormally slow Time Machine backups but it often works when there is seemingly no particular issue causing the backup to be slow in the first place. The trick has been around for ages since the introduction of Time Machine, and since it still works to this day suggests something. Know of any other tips to speed up unusually slow Time Machine backups?

Now it still works to fix the problem and speed up a backup. OMG thank you so much that is a fantastic tip. Thank you so so much!!! I have spent a ridiculous amount of time and have tried so many different ways to get Time Machine Backups to work properly, this has improved the speed x10 at least — Finally some relief: This command does seem to be helping. I bought a new 8TB backup disk for my iMac and the initial backup of about 2 TB worth of data ran for over 10 days and had only backed up about GB. At that rate, it would take about two months to complete. If you look at the provided command:.

Note the double-negative, so this in fact lets Time Machine run at full speed. To re-enable throttling, you can simply change the 0 to a Holy Crap!!! I understand the purpose of throttling in certain contexts mother-in-law, annoying dog next door, etc. Left my mac to backup over night yesterday and woke up today to see that just 9 gb!? My god this was wonderful. It takes effect instantly no need to restart the backup and I immediately saw a 50x increase in backup speed.

It was looking like it would take close to 20 hours — 10 so far with 12 more showing. I tried this command and it the time immediately dropped to hours but at least I can tell that it is moving much more quickly. I did notice that while it was off and the backup was running the screensaver was jumpy, so I guess this could be one way macs keep everything running smoothly by keeping some processing power in reserve? The difference in speed is unbelievable. Thank you so much! Can you help a beginner? Where do I go to enter the command: The first tme I tried this it worked like a charm.

This time, however, nothing. My backup is loading at single figure kbs. Does anyone have any idea why this might be? I like to run DiskWarrior on Time Machine backups from time to time. Optimizing the huge TM directories has helped me when TM seems slower than it should be. Everyone can boot into Safe Mode. If the Mac works, safe mode works.

Time Machine Slow? Speed it up With This Terminal Hack! - All About Apple

However, this particular problem with EXTREMELY slow time-machine backups persists whatever I try to do, including all four of your suggestions, and I have also followed other several forums with various suggestions, none of which help. It seems to be a serious problem in Mac OS that has not been resolved for a long time. Right now I am in the middle of a new back-up which has been going on for more than five hours, and is still only halfway.

I wish Apple would wake up to this one! Someone else in this comment section suggested to disable to low priority throttle. I seldom use my macbook in OS-X. I only run Microsoft office in OS-X. The easiest way is to just set it to do automatic backups and connect an external hard drive. I heard it dies incrimental backups based on the results of the index searches. My mac has no index files because it laxks spotlight.

Time Machine uses Spotlight to do indexing for the backup. Depending on how you disabled Spotlight, Time Machine may also be disabled. If your Spotlight is having problems those same problems can crop up in Time Machine. Time Machine is file based rather than block based and will be slow with a large VM hard drive file. You can exclude the file. I did not think that Time Capsuke supports remote backups over the internet.

4 Tips to Speed Up a Slow Mac

Best to always maintain a second backup. Meanwhile, another significant problem I have encountered is the slow Time Machine backup. Any suggestions would be much appreciated. Yes Time Machine now has to backup the new OS installation as well as your files, it may take a while to complete that. In my instance it was spotlight that was stalling the backup.

2. Check your Startup Items

Stop spotlight from searching your time machine drive and hey presto, backups should take no time. Apple should fix this. Its obviously the algorithm setting itself tasks which accumulate over time.

I had slow backup running OS x Mavericks Speed was about 2 GB per hour. I did a permission fix on my drive using disk utility. I rebooted into safe mode. After the fixes my first backup took less than 6 hours so it was backing up at a rate of over GB per hour. I did not try any of the Safe Mode procedures or Terminal system hacks. I got negligible improvement. I disconnected from the network, in my case by unplugging the ethernet cable but others may need to turn off wifi.

Then I turned off the full-time virus monitoring on the whole machine.

The full speed was immediately restored. Or for those who use the continuous Time Machine scheduling. And perhaps with this clue Apple can modify its Time Machine code to improve its dismal performance. With Sophos, I excluded the backups directory on my external drive from on-access scanning.

If a Time Machine backup takes longer than you expect

Speed gain was so good I thought I broke something at first. Rest of the machine still being scanned as normal. Disabling the anti-virus, the transfer rate went dramatically up. If I in Sophos specified the folders: OMG, thanks a lot! I had exactly the same problem. I found this thread and others that discussed using the terminal, creating sparse bundles etc etc. I finally just upgraded to the latest firmware for the hard drive and a backup that had run for over a week!!! I have been fighting this slow backup for awhile now.

I finally found what works for me. I turned off the Avira real time protection and now my Time capsule works likes a champ. I upgraded to OS Sierra — was thinking that had an effect. Had to do a full backup. Did you upgrade your MacBook Pro? I also suffered from very slow backups. I discovered that Kaspersky Internet Security was the problem. As soon as I turned off protection, the backup time plunged about two hours to backup Gbytes of data. You can tell Kaspersky to ignore TM. Here is the official solution: Please add this to the Trusted Zone in Kaspersky to exclude it from scans: Open Preferences: Thank you!

The terminal command worked for me! At GB of data to transfer, this was a lifesaver. Can this terminal throttle command be run whilst backing up. Been backing up for two days half way through, not sure if i want to stop it and try the command. I just ran across this advice, and your question.

You probably figured it out awhile back, but I just tried the terminal throttle command while running a Time Machine backup, and it worked just fine. Sadly this terminal throttle command did not help me. There is something else that is happening with Time Machine that needs genuine Apple Support. It should be minutes, not even hours. Anyone have better solutions? I tried the sudo sysctl debug. Only 10 GBs transferred out of in over 36 hours.

I force quit the process and the back-up took off. I did the safe reboot and I think it worked! Previously, it took 24 hours to back up MB, at that rate, it would take me 10 years to back up my computer!!! Thank you!!! It slowed down again. Name required. Mail will not be published required.

Mac Running Slow? 14 Things you MUST try

EDIT 3: After many, many hours, Time Machine has finished scanning and is now backing up! I'd still like to know why it took so long I didn't expect updating to El Capitan to take so long. I excluded system files as well, although I guess I'm in for another long wait since I just removed them from the exceptions list. It's also a good idea to re-enable the throttling after your backup finished successfully with the following command. You can find the content of the file at this gist. It created a new. If you didn't want to delete your existing backups, you could try one of the other suggestions on that page:.

I had similar problems after moving to El Capitan - backups even small incremental ones slowed to a real crawl.

AFP is was? I have no clue why these requests failed, but the number of these failed attempts is HUGE - the actual data transferred is minuscule compared to the number of these failed requests - and hence the slow, crawling, speed. That's it. Previous backups were good, and incremental backups that happened after this have been FAST.

I wasn't able to fix problem, however, I have found out that my time machine slows down when it backups data of other users not logged in one. Might be some problem with permission exists in the other's Users's folder files. When I added that user into exception list, TM rocks. Turned hr backup into 4-hr! However, it doesn't remain after a restart. Since I'm not very versed on shell scripts, I googled around enough to create an Automator workflow that prompts for user to input the root password, then executes the terminal command. I chose to confirm success with a notification center alert.

I saved the workflow as an application, and added it to my login items. So now at every login I'm prompted to enter my password again to "un-throttle" Time Machine. There are ways to make the process invisible with shell scripts, but it's a bit complicated needing the root access gained by the sudo command. One could also hard-wire the password inside the Automator app if unconcerned about security.

Not recommending. I'd post the workflow app here but apparently can't upload a file to this answer. So I'll attach a jpg of it for anyone to recreate if they like. Note the Pass Input "as argument" for the shell script. My problem was remedied by D. Hoard's article: Too bad - I bought the Time Capsule simply to avoid this kind of incompatibilities and here I am - all Apple devices and a lousy experience, waste of time. I hope you others find a lasting solution. The console is getting a new entry for mdworker about every second - is this normal while backup is happening?

Edit 2: The laptop has two user accounts and it may be that logging into the second caused the rest of the backups to proceed. Worth testing if you're in a similar situation. EVERY hours, restart your computer. Please see this note from Apple:. The first time you use Time Machine, set it up in the evening so that the initial backup can be done overnight. If your backup disk is a Time Capsule, leave your Mac in the same room as the Time Capsule for the initial backup, or use an Ethernet cable to connect your Mac to one of the Ethernet ports on the Time Capsule. Virus scanning software can make Time Machine backups very slow.

If you use Norton AntiVirus or a similar product, try to exclude your backup disk from automatic scanning. Also make sure you are running the latest version of the virus scanning software.
