How can I switch to Linux Mint with a clean install and keep my 300GB of data (with metadata) safe? (sh.itjust.works)

Hi all, I'm planning to do a clean install of Linux Mint on my laptop and completely remove Windows. I have about 300GB of personal data on the system and only one SSD, so everything is currently stored on that single drive.

Here’s what I want to do:

Back up all my data safely, without losing any metadata (timestamps, folder structure, etc.).
Wipe Windows and do a clean install of Linux Mint.
Restore my data with everything intact—timestamps, folder structure, and metadata.
Be able to open or run file types that are only supported by Windows, like certain .exe, .msi, or specific file types.

I don’t have a second internal drive, so I’ll probably use an external hard drive or cloud storage.

What i want to know is:

1.What’s the best way to back up and restore my data safely while preserving all metadata?

2.What tools or methods should I use for backup and restore?

3.How can I access or use files that are only supported by Windows once I’ve switched to Linux? Are there workarounds or compatibility layers?

I’m fairly new to Linux, so beginner-friendly advice would be awesome.

Thanks in advance!

Best to get both. Two copies of the data is better then one. Ideally have three. One being remote is also a plus as that will protect you in case your house burns down or something else drastic.

1.What’s the best way to back up and restore my data safely while preserving all metadata?

There is no real best way. Loads of things can be used to achieve the same purpose. But there are two main end goals: either copy/sync the data with a tool that can preserve timestamps or use a tool that can archive the data into a single file (that can optionally be compressed - like zip). Or for cloud providers they typically have their own tools that can do the syncing for you and will typically preserve timestamps by default. Just find one with a sync tool that also works on Linux.

There are loads of backup tools for windows that can do these things - though you should use one that does not use its own propriety format but instead something more open that can be read from the Linux side. I don't use windows these days so cannot advice on what the best tools here are.

Otherwise you can do this from a Linux Live USB using Linux based tools. If you are fine with the CLI then a simple way is to just mount the drives and use the rsync cli utility to sync the data you want across. rsync also lets you cancel and resume the sync which can be handy for larger directories. Or use the archiving tool tar to create a archive of the data on the other drive (this can be optionally compress). You should be able to use the filemanager to create archives as well which might make things a bit easier and should preserve timestamps - but just copying the data in a filemanager I don't think tends to preserve timestamps though so best to use the CLI for that or a dedicated tool.

What ever you decide to do test it on a small folder first and see if it does what you expect/want it to before committing to copying large amounts of data.

3.How can I access or use files that are only supported by Windows once I’ve switched to Linux? Are there workarounds or compatibility layers?

This depends on the file formats you care about. Some things are already supported by native Linux programs, others are not. Some windows only programs can work in compatibility tools like WINE - but I would only do that as a last resort. Personally I would figure this out before you reinstall your system. Start by finding Linux friendly programs for the files you need to use and see if they work with the files you want - if not try converting them before switching. Most Linux programs can also run on Windows so it is best to find these alternative and test them out before wiping your windows install. You can also boot up a Live USB and check things that way before committing to a install and wiping your system.

You can also (in addition to backing things up properly) buy a new SSD for your laptop and swap them around - keeping the original install in place in case there is something you forgot or need to switch back to access some old program you didn't think about.
