Time Machine Disk Size
There are a lot of cool things you can do with Apple’s Time Machine backup service in OS X – which has a lot of power tools that most people aren’t aware of. One such feature is the ability to restrict the size of the Time Machine backup. While this isn’t an “official” feature of Time Machine as much as it is various hacks you can perform, it does the job quite well.
MacFormat recently detailed a few methods that you can use in one of their Friday Q&A sessions – we’ve included a particularly useful segment below. Check out the original post to read MacFormat’s entire answer!
Q. I’m a big film fan and I spend a lot of my time porting over films to my Mac and its external hard drive. It’s great because I can watch movies on the go without having to lug around an ugly black CD wallet. However, I’m also running Time Machine into this external hard drive, and if I’m not careful I’m going to run out of space. Is it possible to control how many backups Time Machine makes onto the external hard drive? I don’t know if I need the data from way back in October.

- At this point the Backup Disk is selected and the next Time Machine Backup will start in 120 Seconds (2 Minutes). Excluding items from Time Machine backup plan (Options): Open System Preferences. Open Time Machine. Click on the Options button. An options window opens; Click on the + button to change what is excluded by Time machine.
- Time Machine saves hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for everything older than a month until the volume runs out of space. At that point, Time Machine deletes the oldest weekly backup. Time Machine's user interface when retrieving a file uses Apple's Core Animation API.
- Vol size limit = size in MiB (V) Useful for Time Machine: limits the reported volume size, thus preventing Time Machine from using the whole real disk space for backup. Example: “vol size limit = 1000” would limit the reported disk space to 1 GB. IMPORTANT: This is an approximated calculation taking into account the contents of Time Machine.
Time Machine Disk Sizes
A. […]Networked Time Machine volumes are created as sparse image bundles, which have their maximum size set when the bundle is first created. This lets you fool Time Machine into using less than the whole disk by putting large files (such as non-sparse disk images) on the disk before you turn on Time Machine for the first time. Once the sparse image bundle has been created, you can remove the padding files and the Time Machine backup won’t grow beyond this original limit. […]
Time Machine Disk Size Limit
Virtual machine and disk performance (Linux). (IOPS) and throughput performance limits based on the virtual machine type and size. OS disks and data disks can be attached to virtual machines. Let’s continue with our StandardD8sv3 virtual machine. Except this time, we'll enable host caching on the disks. Also, now the VM's. In other words after performing a disk cleanup by pressing the Clean Up Virtual Machine button on the General sheet of the Virtual Machine's Settings you'll notice that the.vmdk extents at the end of the disk are still rather large and not 320 KB as would be expected if the extents were empty.
