[SOLVED] Trying to make a sd card clone without taking the sd card out of the GBZ

Hallo people,
because my GBZ does not have a microsd adapter, each time that I want to mess arround with my system I need to open the GBZ in order to take the microsd card out to be able to make a backup...
by doing so the screw holes are getting screwd
which is actually not funy
so I tried to do it by inserting a micro sd adapter in one of my Usb ports to make a backup via ssh using Putty login in as "root".
Inside the CLI i tiped in
Code: Select all
git clone https://github.com/billw2/rpi-clone.git
then
then
the devices shown were like this
Code: Select all
root@retropie:~# ls -la /dev/disk/by-id
lrwxrwxrwx 1 root root 9 Dec 1 18:36 usb-Generic_Mini_SD_Reader_00000000000006-0:1 -> ../../sdb
lrwxrwxrwx 1 root root 10 Dec 1 18:36 usb-Generic_Mini_SD_Reader_00000000000006-0:1-part1 -> ../../sdb1
lrwxrwxrwx 1 root root 9 Dec 1 18:36 usb-Generic_USB_SD_Reader_00000000000006-0:0 -> ../../sda
Code: Select all
root@retropie:~# sudo rpi-clone sdb -v

---------------------------------------------------------------------------

-----------------------:
Ok to proceed with the clone? (yes/no): y
Syncing file systems (can take a long time)
Syncing mounted partitions:
Mounting /dev/sdb2 on /mnt/clone
mount: wrong fs type, bad option, bad superblock on /dev/sdb2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
Mount failure of /dev/sdb2 on /mnt/clone.
Aborting!
after that i tried the command dmesg to see what it says and Ive got this
Code: Select all

I really do not know what to do and I would really apreciate any help.
Thanks in advance

Full post here, not from me
https://raspberrypi.stackexchange.com/q ... ard-reader
In your case, device seems to be sdb
1) Make sure their is a card in your card reader and then plug it into the Raspberry Pi. If using a powered HUB then the Raspberry Pi will not reboot
2) Then run "dmesg | tail" and look for /dev/sdX where X is a, b, or c (for example, the below uses 'a').
3) Now as long as the plugged-in card is the same size (or larger) than what is in the Raspberry Pi SD card slot, you can run "dd if=/dev/mmcblk0 of=/dev/sda bs=1b"
NOTE: /dev/mmcblk0 refers to the whole SD card and not any one partition
NOTE: /dev/sda refers to the whole SD card in the external reader and not any one partition
4) This will take anywhere from 10 min to an hour depending on the size of the SD card you have. When it's done you should as a minimum run "fsck /dev/sda2" since you copied a running "live" filesystem.
Not only is this a backup of your whole SD card (W95 "/boot", and Linux ext4 "/"), it can also be used to boot the system.
PS: I've also used this to copy my bootable 4 GB SD card to a 16 GB card and after using fdisk to make an ext4 on the remaining 12 GB and mount as /opt1.

Hallo Yaya, thanks for taking the time to read and reply my post!, I've been really bussy in the last time so I didnt (and I steel dont) have the chance to try your solution, I just wanted to say thanks for your reply,... I ll modify the post to [Solved] when i have the chance to invest some time on my GBZ to see if I can make it work... it would be really practical cause I dont have an external micro sd card reader, I've already try making one (the simplest way posible, just a reader and some wires to pp15... and so on) and the pi didn't boot at all, so I'll try with this solution and if I don't manage I'll see if I can get the reader to work again and modify a little the case. I'll head back.
Thanks for your time

Hallo again!
so I got finilly time to do it
I actually do not know if its working or not, I ran the command you told me, the thing is that the sd card that I have on my GBZ its 16Gb!, if a normal 4Gb sd card takes one hour then mine should take 4
Code: Select all
pi@retropie:~ $ dmesg | tail
[ 7344.573702] sd 6:0:0:0: [sda] Attached SCSI removable disk
[ 7344.574464] sd 6:0:0:1: [sdb] 62521344 512-byte logical blocks: (32.0 GB/29.8 GiB)
[ 7344.575445] sd 6:0:0:1: [sdb] Write Protect is off
[ 7344.575478] sd 6:0:0:1: [sdb] Mode Sense: 03 00 00 00
[ 7344.576368] sd 6:0:0:1: [sdb] No Caching mode page found
[ 7344.576394] sd 6:0:0:1: [sdb] Assuming drive cache: write through
[ 7344.610553] sdb: sdb1
[ 7344.619858] sd 6:0:0:1: [sdb] Attached SCSI removable disk
[ 7920.113764] sdb: sdb1 sdb2
[ 7927.373831] EXT4-fs (sdb2): Unrecognized mount option "uid=1000" or missing value
after this I didnt find the dev/sd a or b, so I tried running the command you told me
Code: Select all
sudo dd if=/dev/mmcblk0 of=/dev/sdb bs=1b
the pi seems to be "thinking" since two hours!! I dont need it at the moment but its kinda annoying. I am working via ssh the conections seems to be working good (since I didnt got any message).
thanks for taking the time of reading this post, any help is welcome!

If you changed bs=4096 or something larger it would go a lot quicker.. you are asking it to write 1 block (512 bytes) at a time, that will seriously take a long time
bs=1M would copy it as 1mb chunks at a time which would go at a reasonable speed

Oh thanks kite for the advice, i thought that as the system was live, this param should be let at 1byte for a perfect sure copy.
