Are you backing it up to your phone itself (not nessicarily recommended) or to a USB stick?
AngWay i think a backup is setup and it's saving to my phone but i went into files and i can't find a backup file or anything.
You can find it in Files > Menu > Your Phone Model (Pixel 6a, 9 Pro, etc.) > Three Lines in upper right corner > Show Hidden Files You should have a folder labeled .SeedVaultAndroidBackup. The backups are in there. If you backed up to a USB stick, you'll have to have it plugged in to view this.
AngWay how do i do backups so i can save everything if i ever wanted to wipe my phone then reinstall stuff?
Don't rely on Seedvault. It always has bugs and isn't a reliable backup restore tool. Do manual backups of photos, files, important stuff.
