Hi,
I've been trying to back up a Pi installation using a tool called image-utils
(written by a contributor to the Pi Forums). This tool backs up the running
system and writes the image to a specified destination. I've used it many
times before but I recently had an issue because my image file was bigger than
the 4 GB limit on FAT32. I was advised by the author to format the stick with
ext2.
This I have done, but can no longer mount the stick on the Pi. Initially I
thought that the problem was due to ownership and permissions; formatting
creates a partition owned by root. I've now changed ownership and permissions
on the stick (labelled Backup) to:
drwxrwxrwx 3 terry terry 4096 Nov 28 13:04 Backup
using my PC. However, I still get an issue when I plug the stick into the Pi.
Having created the directory /media/usb/ on the Pi, I do:
pi@minster-music:~ $ ls -l /dev/disk/by-uuid/
total 0
lrwxrwxrwx 1 root root 10 Nov 28 13:05 5183463e-4eee-4e13-99c2-f0871ad6d8b8 ->
../../sda1
lrwxrwxrwx 1 root root 15 Nov 28 11:10 568caafd-bab1-46cb-921b-cd257b61f505 ->
../../mmcblk0p2
lrwxrwxrwx 1 root root 15 Nov 28 11:10 C839-E506 -> ../../mmcblk0p1
then I do:
pi@minster-music:~ $ sudo mount /dev/sda1 /media/usb/ -o uid=pi,gid=pi
mount: /media/usb: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error.
As you can see, the Pi doesn't like this.
This procedure works if I use a FAT32 Stick.
What have I mised?
