(Optional) Compress with 7-Zip to save space

These steps are completely optional, if you can store your backup without compression, do that. This is useful if you're wanting to upload your backup to a service like Google Drive, Mega, MediaFire.

Step 1. Get 7-Zip here and install it.

Step 2. Right click your backup folder you copied from your SD - 7zip > add to archive.

Step 3. Default settings are fine. Use the ... to specify where the zip will be made.

Step 4. Delete the backup folder if you want, compressed zip is the same thing just smaller. Depends on what was on your NAND but it saves me 10GB~.
