You are in the best position to answer this for yourself, Dick
See my screenshot below and then I will elaborate.
SCREENSHOT 1 - WIZARD'S SUMMARY OF TIMESHIFT SNAPSHOTS
Using our File Manager, Nemo, in Cinnamon, we can see the state of our Timeshift snapshots taken. On the left, with
my partition, I have it named Timeshift, and we can do that with yours next few days.
The path for the partition is /media/chris/Timeshift , and it shows me it is on /dev/sdc4. Both it and the main pane tell me that I have 55.0 GB left in that partition, and the main pane tells me that there are 34 snapshots (1 folder per snapshot).
Your left-hand pane should tell you something like Timeshift being described as :
300GB Volume, and the cursor "Smart Tip" will show
/media/dick/abf2d.... (long string, truncated)
... and 200GB or so unused.
Looking at my screenshot above, again.
In the main pane, the first folder is described as
2018-10-25_08-51-47
and the last of its kind as
2019-02-01_14-35-37
So the first of my snaps was conducted 25 October last, at 8:51 AM, and the last on 1 February at 2:35 PM.
Now that is all very well, but it's no good to us if those folders don't contain what we need to restore. True?
Your GParted screenshot of the T5 showed us that 73.62 GB was used at that time, in snapshots, out of a size of 292.97 GB.
Open a fresh instance of Terminal and type in and enter the following (my comment has a # in front of it, it is not a command)
But also read below the code, first and I will give you a tip
Code:
cd /media/dick/abf2d1ba-b87d-4a34-a743-7f180af09e5e
#followed by
du -ah
TIP - with the 1st command, all you need to do is to start typing in cd /media/dick/abf ... or so, then press
TAB - the rest will complete for you. This is called Tab (auto)Complete. Useful for long filepaths.
With the 2nd command, as soon as you press enter, be prepared for a lot of activity. Output will spool off for a long period of time, go and make a cuppa tea or coffee
My last few lines look like this:
4.0K ./timeshift/snapshots/2019-01-02_10-12-01/info.json
31M ./timeshift/snapshots/2019-01-02_10-12-01/rsync-log-changes
13G ./timeshift/snapshots/2019-01-02_10-12-01
312G ./timeshift/snapshots
312G ./timeshift
312G .
chris@SylviaCinnamon-WD /media/chris/Timeshift $
My highlighting
So, if your figure at left bottom is many GB, then Timeshift is doing its voodoo fine, it's all on the T5, and you can unplug the Toshiba and take it to the big smoke.
Let us know how you go.
When you come back from the city, we can get the new SSD set up, use Timeshift to restore LM 18.3, and
then reorganise the T5.
Cheers
Chris
