This can be checked from the command line by comparing the output of: $ grep swap /etc/fstab # shows the configured UUID $ blkid |grep swap # shows the correct UUID If the two differ, I recommend copying the correct UUID, using $ sudo nano /etc/fstab to edit the config. file, and then restarting the system. I would be interested to know if that was the problem in this case, and if so, whether the proposed solution cured it. The swapon command can be helpful here too. sudo swapon -s will show swap partitions in use. sudo swapon -L will start using the partition with the specified label as a swap partition. sudo swapon -U will start using the partition with the specified uuid as a swap partition. You can also do:- sudo swapon /dev/sda3 or similar. As you say, to make it permanent you need to edit /etc/fstab but for testing the above might help. -- Next meeting: Bournemouth, Tuesday 2011-06-07 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ How to Report Bugs Effectively: http://goo.gl/4Xue

Sorry, I should clarify that. When I say "you will lose a lot of data" I mean that your backup will be incomplete. -- Next meeting: Bournemouth, Tuesday 2011-06-07 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ How to Report Bugs Effectively: http://goo.gl/4Xue

DAMHIKT A better way to do this is:- cd /home cp -a $USER /media/backup Finally, be aware that if you have symbolic links to data _outside_ your /home/$USER directory, that data will not be copied. The links will be preserved - that is to say, the backup will contain a link to that data, not the actual data. -- Next meeting: Bournemouth, Tuesday 2011-06-07 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ How to Report Bugs Effectively: http://goo.gl/4Xue

Peter, you need to use the -a switch (although there are other ways): cp -a from-here to-here That will copy all directories recursively. -- "You can have everything in life you want if you help enough other people get what they want" - Zig Ziglar.

I've been trying to copy from a terminal but get the message "Omitting Directory". Starting from the directory /var/backup I used cp filename /media/External/Ubuntu/backup.
