Any workarounds for this? </div>Maybe the auto-sleep disconnect the drive? Is there any related messages in /var/log/syslog? As a work around you can set a crontab to prevent the drive from sleeping, maybe a 'ls -l /var/backup' for every 10 minutes.</blockquote><div>Hey, I agree it sounds like a sleep issue, but this solution seems like overkill, if this is the only time it is an issue why not add the remount to the start of the backup script? You _may_ be able to run `sudo mount -o remount /dev/sda1` instead of the two separate commands. If you don't want to have to enter a sudo password and also don't want to give blanket nopasswd access to mount then write your remounts in a script, chown root; chmod 744; then add permissions for the script to you sudoers. cheers, Owen. </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div>
