Going forward, I'm wondering if I should have a cron job run a thinning command every week or so, just to keep things clean.

#SNAPSHOT MAC OS SIERRA WINDOWS#

I was trying to make a Boot Camp partition to run Windows and I didn't have enough space, even tho most of that space was just being taken up by local snapshots.

I was wondering how I was losing all my free disk space so suddenly, and I would assume that these local snapshots would get thinned automatically, especially when additional space is required so you shouldn't have to worry about this too much. Over the course of these trials my hard drive has gone from ~50 GBs free to ~277 GBs free. I'm willing to bet that urgency being set to 1 means 'very urgent' and urgency set to 4 means 'meh, whenever'.

You can see that it thinned the last remaining local snapshot and now when you listlocalsnapshots you'll see only the latest one but it is tagged as (dataless).

Let's go back to just 1 GB for the purge_amount but try with urgency set to 1 (another omission in the manual is whether 1 is high or 4 or high, but thinks 4 is high): $ tmutil thinlocalsnapshots / 1000000000 1 So, when it gets to the last local snapshot, it must have to do with the urgency option rather than the purge_amount. Let's try 100 GBs: $ tmutil thinlocalsnapshots / 100000000000 Let's try increasing the bytes to 10 GBs: $ tmutil thinlocalsnapshots / 10000000000 You can see it didn't do anything this time. Let's try running that same command one more time: $ tmutil thinlocalsnapshots / 1000000000Īnd again: $ tmutil thinlocalsnapshots / 1000000000Īnd once more to try and remove that final local snapshot: $ tmutil thinlocalsnapshots / 1000000000 Here's what's happened to my local snapshots list: $ tmutil listlocalsnapshots / With purge_amount set to 1000000000 (1 Gigabyte): $ tmutil thinlocalsnapshots / 1000000000Īnd if I run that again: $ tmutil thinlocalsnapshots / 1000000000 When running without the purge_amount and urgency options, it's likely that no local snapshots will be purged: $ tmutil thinlocalsnapshots / To show you what's happening in real-world usage, here is my starting list of local snapshots: $ tmutil listlocalsnapshots / If urgency is not specified, the default urgency will be used.Ī noticeable omission is what the default urgency actually is and whether 1 is high urgency or 4 is high urgency. When purge_amount and urgency are specified, tmutil will attempt (with urgency level 1-4) to reclaim purge_amount in bytes by thinning snapshots. Thin local Time Machine snapshots for the specified volume. There's not a tonne of information from the basic tmutil function but you can call man tmutil to get more details, specifically on thinlocalsnapshots: thinlocalsnapshots mount_point Spoiler: I went from ~50 GBs free to ~277 GBs free, about 227 GBs difference, over the course of this answer. When I run tmutil in my Terminal I see a command called thinlocalsnapshots. You can view your local snapshots like so: $ tmutil listlocalsnapshots / Maybe when it's not connected to the Time Machine disk so that it can still have a versioned backup. I assume these are locally stored snapshots that are created for efficiency of Time Machine. I started looking into 'local snapshots' that are created by Time Machine automatically. It's a little odd and rebooting sometimes works but sometimes doesn't. Then sometimes that shoots back up to 170 GBs. For example, I have 170 GBs free in the morning and then by the afternoon I'm down to 56 GBs. I have noticed that my extra space just suddenly disappears since upgrading to macOS High Sierra.
