Hi,
I am willing to make a clone of my SD card.
So I get using
Terminal
sudo xbian-config xbiancopy start /dev/root file:/media/A07C-31DD/xbian20201212.img
It makes the img file, but the process never ends...
In my process list there is:
Terminal
sfdisk -uS -N1 -f -q /media/A07C-31DD/xbian20201212.img
I have wait a full night... But still not finished.
My SD card is 64GB, img file is 1,8GB and is empty
I also tryed from Kodi/Xbian interface, same issue.
Any idea?
Can I use another tool (clonezilla seems to handle btrfs)?
/media/A07C-31DD/xbian20201212.img << whats that?
Is /media mounted to an external device or network folder? if not, that is your issue:
The image cannot be saved on the medium that is to be backed up
This makes absolutely no sense

This is a USB memory mount on /media
What's a USB memory mount.
Anyway, seems that sfdisk can not deal with it

This is a regular (sandisk) 64MB usb stick.
It runs fine when accessing/writing file on it.
I was thinking this could be a (power consumption) "spin down" option that breaks the process?
No idea
If you still have the stick mounted and the image is on that stick, you could run the command
sudo sfdisk -uS -N1 -f -q /media/A07C-31DD/xbian20201212.img
to see what happens

it replies
Terminal
/media/A07C-31DD/xbian20201212.img1:
I hit enter... no verbosity then...
Remove the '-q' parameter an try again
You see that sfdisk seems to want a user entry and this is the reason why the process stucks

Removing -q option, and choosing "write"
Terminal
/media/A07C-31DD/xbian20201212.img1: write
New situation:
Disklabel type: dos
Disk identifier: 0x3f165629
Device Boot Start End Sectors Size Id Type
/media/A07C-31DD/xbian20201212.img1 * 2048 206847 204800 100M b W95 FAT32
The partition table has been altered.
Syncing disks.
It should consume CPU
but I do not see sfdisk in "top" process list.
I have added some services to xbian: fail2ban and ipfs
Maybe this is creating some changes on filesystem meanwhile it is copied??
I will try to stop those services and try again
Hmmm, absolutely no idea what happens
Seems that the sync process never ends
What about if you run sudo sync from the cmdline?

This command is just running without any output.
I have added --syslog --verbose to btrfs-auto-snapshot command
Terminal
sudo /usr/sbin/btrfs-auto-snapshot xbiancopy --syslog --verbose --img /dev/root /media/usb0/xbian.img
But nothing is happening
looking in dmesg output, I found this

My Rpi4 is 8GB version... Maybe this is the problem?
This is it
On a Rpi4 with 4GB RAM, my backup is running fine !!
Too bad.... backup finished with error
Terminal
...
Cloning root/@, 1347211523 of 1360819721, 99% done
Cloning subvolume root snapshot @ failed
Operation failed with error E_COPY_DATA!
Hmmm, but I can hardly imagine that the size of the RAM should have an influence on it.

Me neither. Maybe the Rpi4 have a defect ?
About my new try, I still have a problem
Code:
Error during copying data occoured (87)
Even by cron.daliy, there is no file created....
What would you suggest me to do? Using a Rpi3 to make my backup?
I'm not sure if this helps.
I think the problem lies somewhere else. I've been using this function for many years on 4 different devices and have never seen such problems.
However, I don't back up to a usb stick or usb disk, but exclusively to network shares (nfs, samba, sshfs).
