CAVEAT TO THIS TYPE OF METHOD
The OP had expressed earlier that she was looking to use what I have provided as a short-term solution to enabling use of Linux, because of her work requirements. She needed a quick fix with what she has available.
This, plus any budgetary considerations on her part may account for not being able to use the worthwhile suggestions from @bob466 at #315 above, but she can speak for herself in that regard.
Sherri USB sticks take a beating when they are used for either
If you are only using it for an hour a day, that is 500 days, but if you are using it 6 hours a day you can do the math.
So if you wish to continue with the above method for a length of time, you would be best advised to get a hold of another large stick.
Any questions on Timeshift can be directed to my Timeshift thread, currently at page 31.
UPDATES AND UPGRADES
By all means run your Updates when you can - the first one will take ages, because LM 21.2 is not the current Mint. Subsequent updates should move faster.
That being said, I would not consider upgrading the stick to LM 21.3.
Why not?

Sherri USB sticks take a beating when they are used for either
- Loading Persistence onto a Linux .iso on a stick or
- (as is the case here, particularly) Installing a full Linux Distro onto a stick.

Why not?
- Around 20 April, Ubuntu will release Ubuntu 24.04 Desktop, codename 'Noble Numbat', and Ubuntu is what Mint is based upon
- As a response, typically by end of June, Clem Lefebvre's team at Linux Mint will release LM 22.0 or similar product, so you may as well wait until then and get the new LTS version.
