Another is Gemini 2 , which can find large duplicate files. Finally, a warning. When cleaning up junk files, take some quick wins, and then move on.
The law of diminishing returns is at work here: spending more time on cleanup will free up increasingly smaller amounts of space. The scans you performed to locate junk files can be time-consuming; they can potentially take more time than to just back them up in the first place.
One of the bottlenecks in a backup is the external drive you back up to. These vary quite a lot in speed. Choosing a fast drive will save you a significant amount of time—your backup may become up to four times faster! Most external hard drives today spin at 5, rpm. It offers desktop and portable versions. For twice the price, you can purchase a faster drive, such as the Fantom Drives G-Force 3 Professional. How much time would this save? Probably hours. If the backup takes six hours on a standard drive, it will take just four hours on a 7, rpm drive.
You just saved two hours. For even bigger time-saving, choose an external SSD. You may have experienced the huge speed boost you gain when you use a solid-state drive as your main internal storage. In other words, they are two to four times faster. Using one will slash the amount of time required for a backup. A backup that would have taken eight hours on a platter drive may now take just two.
Depending on your circumstances, you may find the cost justifiable. If you need to back up huge files every day, an external SSD will save you many hours of waiting. Here are a few ways to achieve that. They recommend that you configure the software to exclude your backup drive from being scanned.
This tip promised to save more time than all the others put together, but I was disappointed in my tests. However, many others have seen a significant increase in backup speeds using it, and you may have more luck than I did. There's gotta be a different explanation.

Welcome to Ask Different. This is not a 'forum' that acts like a chat about the problem. I it's good to research the problem and if you have a good answer, post it with your research. As nohillside states, improve one answer with an edit instead of just posting more 'answers'. Please take the tour to see how the site works. As I said, the client and server are both hardwired via ethernet and they are in the same room. Even so, it takes about a month for the initial backup of the 1Tb drive on my Mac Air.
The backup disk is an external 5Tb drive connected to my iMac. I am not using any virus scanning software. The Overflow Blog. Podcast Explaining the semiconductor shortage, and how it might end. There are multiple storage upgrade options on the market. Two brands are among the best in particular: OWC and Feather. Note: Make sure to read compatibility notes for SSDs. Feather has a nice chart in the description which tells which of their products is compatible with which Mac.
Another way to check the upgradeability of the Mac is crucial. The good thing about upgrading primary storage and improving its read performance is that Time Machine is not the only thing that benefits from the upgrade. Literally, every app runs faster possibly 10x faster now.
However, when it comes to the backup process, the biggest bang for the buck is choosing the right external hard drive. For instance, I tested the difference in performance between backing up on an external hard drive and on a thumb drive. Yes, you can. Flash drives work exactly the same way as external hard drives. The difference is usually the speed: flash drives are usually way slower sometimes 10xx slower.
As expected in my experiment, the flash drive performed very poorly. Since my flash drive was limited to 32GB, I backed up a brand new MacBook without any applications installed. The backup size was around 20GB. If you need recommendations for the best external devices for Time Machine, you can find them below. But even if you decide to go with drives other than I recommend, please go with well-known brands.
Note: these are not real names, I just made them up, but you get the point. I am just amazed at how unknown brands get thousands of 5-star reviews on Amazon, and I try to stay away from those.
Remember, losing a backup may be much more costly than investing in a more expensive but reliable brand. Hi, I am Al. I've been working with computers for more than 20 years and I am passionate about Apple products. Check out our video about how GPS satellites work.
But did you know that GPS relies on time-travel calculations to help you get around town? GPS satellites orbit around Earth very quickly at about 8, miles 14, kilometers per hour. This slows down GPS satellite clocks by a small fraction of a second similar to the airplane example above. GPS satellites orbit around Earth at about 8, miles 14, kilometers per hour. Credit: GPS. However, the satellites are also orbiting Earth about 12, miles 20, km above the surface.
This actually speeds up GPS satellite clocks by a slighter larger fraction of a second. Here's how: Einstein's theory also says that gravity curves space and time, causing the passage of time to slow down.
High up where the satellites orbit, Earth's gravity is much weaker. This causes the clocks on GPS satellites to run faster than clocks on the ground. The combined result is that the clocks on GPS satellites experience time at a rate slightly faster than 1 second per second. Luckily, scientists can use math to correct these differences in time. If scientists didn't correct the GPS clocks, there would be big problems.
