Set backup limit per client for Time machine ?

[prakashwaghwani]

Hello All,

We are running 9.6.6 version in our env. At the moment the user machines (Mac El Capitan) time machine is backing up to the storage but their is no set limit. We would look to know if there is any way to limit every user to use for eg: 50 Gb only. And when they reach 50 Gb, time machine should delete/overwrite the old backup.

I came across this article (https://www.jamf.com/jamf-nation/third-party-products/files/198/time-machine), but i guess it doesn't work anymore with El capitan. Please let me know!

thanks!

You can use a script that includes the following line:

sudo defaults write /Library/Preferences/com.apple.TimeMachine MaxSize -integer XX

where XX represents in MBs the maximum size you want Time Machine to backup.

Hi thank you for your reply! that is helpful. We will try that in the env.

Question: If the current user time machine is using lets say 200GB in backup on the volume, do you know what would happen if I apply the above command and restrict it to 50 GB?
