Backup failed

[cmmdrdata]

I am using tinycore from CD with some success - after frustrations with an iffy DVD drive - and want to try the persistence offered by Backup. When I direct the backup to my ext4 formatted flash drive (4Gb single partition) it fails. Could this be due to the formatting taking place in my XUbuntu install? differing root/user id's? If I chown and chmod can it be fixed or should I format the flash drive as root or tc from within tinycore?

Code: [Select]

sudo su
mkdir /mnt/USB
mount /dev/sdXY /mnt/USB
cd /mnt/USB
mkdir tce
chown root:staff tce
chmod 775 tce
touch tce/mydata.tgz
chown root:staff tce/mydata.tgz
chmod 775 tce/mydata.tgz

This should fix it.

Oh, that makes sense PoliKuo. Thanks for the response. I'll try that today and confirm all is well
