- Jun 15, 2016 Time machine see that image as a file. Lets have you log into a 40gb VM and all you do is make a 5 kb text file and leave the VM. Time machine will back up that whole 40 gb image as a result of.
- Types of disks you can use with Time Machine on Mac. You can use Time Machine with an AirPort Time Capsule, with a network-attached storage (NAS) device that supports Time Machine over SMB, or with an external storage device connected directly to your Mac (such as a USB or Thunderbolt drive).
10.5: Create a Time Machine size limit for networked disks Nov 21, '07 07:30:03AM. Contributed by: Anonymous I am using Time Machine to back up my MacBook Pro on a Samba drive connected to a Linux machine, per this hint. Well, if you have a spare Mac around, you can set up your own Time Machine server for just $19.99 plus the cost of whatever size hard drive you want to use. This article covers how to set up your own Time Machine server on a Mac. System Requirements for a Time Machine server. Time Machine comes pre-installed on macOS and, as we'll discuss in the File Backup section, below, is mostly automated. The only thing you really need to do start backing up your hard drive is.

(I submitted this as an hint here yesterday, but it did not make yet..)
Meanwhile exercise extreme caution in using TM on SMB.
Basically, the problem boils down to the fact that TM is NOT able to recover freed space on a sparsebundle image.. period.
Just rephrasing the last sentece
'Basically, the problem boils down to the fact that TM is NOT able to recover freed space on a sparsebundle image which is on an SMB partition. period.
Meanwhile.. anybody knows why sparsebundle images (created by TM) seem to report being twice as big as the SMB partition they are sitting on ? Weird..
Size Of Time Machine Drive
Based on your comment I set about testing AFP to a third-party NAS. This almost worked.
The old backups were correctly deleted (according to the log in the Console) but after deleting them I can only see one backup in the Time Machine GUI. The other backups exist properly (at least based on a quick examination) in the sparsebundle, but they are not accessible form the GUI.
This is a bit disturbing. It seems like something is really broken with sparsebundles. I don't know what would have to be different for AFP on a 10.5 machine to make this work.
I will test this later over AFP to a 10.5 machine and see if it magically works there. Otherwise it's back to CarbonCopyCloner for me and my $500 NAS..
Hi,
I have tested this and when TM filled the 50 Gig I had set the .sparsebundle size to, it successfully deleted only one backup to make place for the new one. I did not had the problem you are telling about. However, my backup partition (my SMB networked drive) was not full. It is only the .sparsebundle disk image that was full.
How about actually using the maxsize setting in the defaults file?
defaults write /Library/Preferences/com.apple.TimeMachine MaxSize 81920
Where the size is in Kbytes.

Wireless Time Machine Drive
I didn't know that - thanks! This will make it much easier to use the same volume for Time Machine backups and backups of other systems. I was afraid I couldn't do it because Time Machine would gobble up the whole disk.
By the way, if the size really is in kilobytes (why??), then that's a paltry 80MB you've given it. ;-)
That command is verbatim from other tips on time machine floating around on the net. I use 250gig and 400gig for my wife's and my laptops. Think of the 80 gig as a proof of concept..

gosh. Just tried here, and TM still announces 320 Gb available in spite of my 100Gb new limitation.
How does it behave for you?
Do I understand correctly that the TM preference pane should now show 100 Gb max somehow? Do I have to reboot?
Time Machine Drive Size Chart
no, that is not the same. I have read that this allows to skip files over a certain size.
Does this work for local disks as well? (ie: external hard drives connected directly by firewire)
Time machine seems to obey disk quotas, so you can set a quota for the user time machine connects to the share as.
Newbie question: How you do that?
Plus, what if the user want to access the drive for any other purpose? Wouldn't that bring an other problem (i.e. TM filling up all the user's available space of the now 'quotas'ed drive')?
I want to be able to fill up the drive with anything I'm working on if I want to but stll make sure the whole drive isn't filled with TM backups.
Premiere pro 1. Which of the proposed commands is the better one? The one that set the maxsize in the plist or the terminal one?
Has lots of good info on setting up quotas on mac os, other operating systems I'm not really sure about.
The problem is that quotas are at disk level, so if your users are connecting to one machine for backup and other purposes, quota wont help you.
As for the solutions suggested above, the plist one is not well understood yet. -There have been reports of it not working and confusion over units.
So that only leaves the dmg soltution until someone comes up with something better..
oki, i tried that in terminal..
defaults write /Library/Preferences/com.apple.TimeMachine MaxSize 471859200
[400GB limit on a 700GB drive]
seemed like it processed..
but now timemachine is not backing up at all..
what's the reset code?
2gb hard drive. [should have known that before i tried it i know.. :s ]
thanks!
