@msilveira85 your welcome, we are all here to help each other and make this project even better than it all ready is

To create backups for my PI I use Win32 disk imager as I already had it installed from when setting up Retropie on to my SD card.

There are some useful YouTube videos on to how to use the tool but effectively it's just the reverse process of how you got the image of retropie on the SD card but now you are copying an image off and storing it on a PC.

@Dominus said in Backup from Pi3 to Pi2?:

Nope did it myself. Bought a Pi3 for a present, fixed it all up, and I just want to be able to copy that image to my old Pi2. Thanks for the info, I will try updating after I've written the image.

One more thing, if you sent up a Manual overclock on the Pi3, you'll want to probably edit the bood config.txt or it might cause issues on the Pi2 as it can't run at those speeds.

Again, I haven't do it that way, but I dod go from a Pi2 to a Pi3 and it kept my "screaming" 1000 Mhz overclock on the Pi3 until I manually edited the boot config.

@kenibure said in I cannot use this system correctly.:
Problem number 1:
When I try to reboot the Raspberry, the graphic interface disappear, and then appears a command console. I would have to make "sudo reboot" or "sudo poweroff", but then, the system doesn´t detect my keyboard.

I can confirm this is a common problem - especially when the program encounters a fault and exits to terminal. To properly shut down the computer I have to SSH into it and "reboot" since you can't use the keyboard hooked up to the Pi anymore at that point.

...can't help you with how to fix it I'm sorry to day.

RetroPie will give you an LBS error trying to resize on boot with retropie 4.4 with berryboot. It will also not allow you to resize it from retropie raspi-config nor while you have retropie booted and using the command line.

If you are using berryboot with retropie you will need to reboot the pie and do this from berryboots terminal via the berry boot menu with ctrl + alt + F2. I was able to resize an image I took of a 16G SD card written to a 64G card and resize it to expand all available space to the SD.

I cannot take credit for this, but will link what helped me after I spent a few hours trying to figure it out. Back up your SD pay no attention to drive space numbers in the examples below.

Backup your SD card to an image file first!

Enter this to see the current partition usage:
df

E.g.
Filesystem 1K-blocks Used Available Use% Mounted on
rootfs 3698504 3351472 146524 96% /
/dev/root 3698504 3351472 146524 96% /
devtmpfs 494800 0 494800 0% /dev
tmpfs 99820 240 99580 1% /run
tmpfs 5120 0 5120 0% /run/lock
tmpfs 199620 0 199620 0% /run/shm
/dev/mmcblk0p1 57288 19400 37888 34% /boot

The rootfs and /dev/root is the same thing, its just a debian thing the have them both appear as separate

Enter this:
sudo fdisk /dev/mmcblk0

Then press 'p' to see the current partitions on the disk. E.g.

Disk /dev/mmcblk0: 7860 MB, 7860125696 bytes
4 heads, 16 sectors/track, 239872 cylinders, total 15351808 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xa6202af7
Device Boot Start End Blocks Id System
/dev/mmcblk0p1 8192 122879 57344 c W95 FAT32 (LBA)
/dev/mmcblk0p2 122880 15351807 7614464 83 Linux

Now delete the 2nd partition (it won't actually delete the data on it)
Press 'd' > Enter
Press '2' > Enter

Now re-create it:
Press 'n' > Enter
Press 'p' > Enter
Press '2' > Enter

Enter the First sector and the same value as the original /dev/mmcblk0p2 partition (122880 from the above example).

For the Last sector just press enter to use the maximum value.

Now press 'p' > Enter to see the new partition setup.
Finally press 'w' > Enter to write it

Now reboot:
sudo shutdown -r now

Once its back do the resize:
sudo resize2fs /dev/mmcblk0p2

This may take a little while to complete…

Now enter the command
df

and hey presto, you've expanded to use all the space :-)

Filesystem 1K-blocks Used Available Use% Mounted on
rootfs 7513804 3352360 3810208 47% /
/dev/root 7513804 3352360 3810208 47% /
devtmpfs 494800 0 494800 0% /dev
tmpfs 99820 240 99580 1% /run
tmpfs 5120 0 5120 0% /run/lock
tmpfs 199620 0 199620 0% /run/shm
/dev/mmcblk0p1 57288 19400 37888 34% /boot

I'd wipe it, for good measure.

Oh for sure! This is just nice to be able to hit a button and let it do it's thing. It will be the same to restore soon.

ufff, what about to use a 64 gbs SD card?

Anyway maybe you could try to copy and paste files with putty or WinSCP, care, you will need to be root, you will see all files that samba doesnt show up

Cool! Thx , bt sync opt is so clever😉

@cyperghost I got drawn here by @Vanpotheosis' post and thought it could be a good idea to add a little something that may be useful to other drive-by readers. :) I didn't know Linux Reader before, it may be a good advice to some of my Windows-using friends.

@cyperghost said in ROM Save Files:

@Vanpotheosis

I guess people want to show you how smart and elite they are in their linux prowess ;-)

First time that someone called my suggestion as linux elite like by using a Windows programm - sounds strange. But I recommend you to get in touch with SSH and the terminal. It offers the valuest way.

That was @Verced, not @Vanpotheosis. ;)
