Bump? Still looking for any way to modify the USB Sync script to only sync saves. I ended up trying to modify the 01_retropie_copyroms file, but it hangs up on my script.

What I did was add --exclude '*.xxx" for all the rom files on the ROM/BIOS sync line, and swap the source and destination in the rsync command so it now reads the USB path first, and retropie second. Finally, I tried removing the usermod line, since I'm syncing the filed FROM the pi to USB.

The script still automounts the USB, and created the file structure (rsync maxdepth=1) but it fails to fill the directory with the save games.

Still new to scripting (This device is a learning tool) What have I missed?

unmount USB stick

umount "$UM_MOUNTPOINT"

I don't use forums either apparently, because I can't find a way to use that nifty box that allows me to add code. the --exclude DOES have a *.xxx, but it doesn't show up.

@mitu

Hello,

I had the same problem when making the backup, it would be interesting to add these notes in:
https://retropie.org.uk/docs/Updating-RetroPie/#making-a-backup
Change "Make sure you have the correct drive letter for your SD card!" to "Make sure you have the correct drive letter for your SD card! (Choose the partition which is readable by Windows, 'boot' as the source of the backup)" or something similar.

Thank you.

@jonnykesh Alright! That's not so bad :) Guess I should get familiar with gamelist.xml ...

@tmntturtlguy Yes, I'm sure.

Cool solution ;)

I posted annother small script for such purposes here
This creates a zip file for each rom and takes as backup the same folder as the rom located.

It took annother branch instead of searching all files that "could" be a savestate I said, every file with same name except the ROM-name is a savefile.

Thanks for this small script. I appreciate it :)

@chipsnblip Thank you, that is exactly what I'm looking for.

Just thought I'd throw this out there and mark this as resolved. For anyone looking to do what I did which is fully configure your RetroPie, then remove your controller configuration for a clean backup solution (Where you can then restore and configure whatever controller you want as it came Out of the Box) all you have to do is this.

Configure your Raspberry Pi fully (with RetroPie) Make sure all settings are exactly as you'd like with splash screen, themes, core configs, scrapes, roms Delete any save files for the cleanest backups Go to RetroPie > RetroPie Setup > Manage Configurations > EmulationStation > Clear input Configuration Exit to ES, press start on controller and Shutdown System Remove MicroSD card, and insert in computer Create your backup with your favorite backup software, then "Pi shrink" it

All, finally home from my work trip and I updated the rpi-clone tool and it worked perfectly. Thanks for the tip on the new update.

@RedBatman not much you can do unless you shrink the free space down on your installation. I'm sure there's a Linux command you can run to do that. But then each time you move the image back to your sd card you will have to rememeber to expand the file system again.

Disk drill can help to restore deletes images. For instance, with it help I recover deleted photos on my mac. With step-by-step instruction it's easy to do even for me :)

@DarkWolf I use a bash GUI. It has options for Kodi, RetroPie, PIXEL desktop, MC File Manager, RP SetUp Script, System info, reboot & shutdown. Just pick the option and it launches. Any script could be launched from it, including the type proposed by the OP.

Another, option is for him to create the script and just set up a bash alias. So a special codeword or password could just be entered in the shell and the script would run.

So handy for people not familiar with the system. The Pi is basically the living room home entertainment system. In a computer not much bigger than a credit card. What a time to be alive!

@Freakadude said in Strange cloned RetroPie Image issue!:

This is a self backup and restore issue/question.

Sorry for assuming you were using a 3rd party image. I hope our fellows posts above helped you.

Cheers!

@THRobinson You can play with buttons by shorting pins if you have to.

@jesterking said in Backup my retropie error?:

That being said, the best... method of backing up the entire SD card that I could find is in this link

At the end of the day, making an sd backup externally really is the best, most all-encompassing method. The same advice is given in the official RetoPie documentation as well.

https://github.com/retropie/retropie-setup/wiki/updating-retropie#making-a-backup-option-1

Thanks very much - doing a full backup isn't a problem, its just nice to know the options! Will continue to do it this way.
