I'm planning to wipe Windows and move to Linux permanently—no dual boot and no Windows partition kept as a fallback. Before installing Linux, I want to make sure I've backed up everything important rather than discovering later that I missed something. For anyone who has made a similar switch, what did your backup process include? I'd also appreciate general migration tips, common gotchas, and lessons learned.

Make both a full drive image and a separate backup of your personal files. A Clonezilla image gives you a complete recovery option if you change your mind, while a normal file backup makes it easy to access Documents, Pictures, music, videos, and other data. Save the backup to an external drive and verify that the files can actually be opened before wiping Windows.
Most standard files will transfer easily, but Windows programs themselves generally won’t. Make a list of the software you rely on and check whether there’s a Linux version, a compatible alternative, or a need for a virtual machine. Browser sync and a password manager are especially useful for carrying over bookmarks, settings, and credentials. If you have a program that only works on Windows, consider keeping a separate Windows installation or virtual machine rather than assuming Linux will replace it perfectly.
Go through your entire Windows user folder, especially Documents, Desktop, Downloads, Pictures, Videos, and any folders you created elsewhere. Also look for less obvious data such as game saves, password-manager databases, browser bookmarks and settings, email archives, application configuration files, and encryption keys. Making a checklist and waiting a few days before erasing the drive can help you remember things you initially overlooked.
I copied my important files to an external drive, installed Linux on a new SSD, and kept the old Windows drive untouched for a while. That’s a lower-stress approach because you still have the original system if something was missed. For ongoing backups, use a layered setup—for example, one local backup plus another on a separate device or cloud storage. An offline or off-site copy protects against drive failure, theft, and disasters.
Keeping the old drive instead of immediately wiping it sounds like a good safety net. I’ll probably leave it disconnected until I’m sure everything transferred correctly.
