When I run backup perform --trigger database, I get the following error:

[2012/01/13 00:44:05][error] Reason: CLI::SystemCallError
[2012/01/13 00:44:05][error] Failed to run mysqldump on x86_64-linux
[2012/01/13 00:44:05][error] The following information should help to determine the problem:
[2012/01/13 00:44:05][error] Exit Code: 1280
[2012/01/13 00:44:05][error] STDERR:
[2012/01/13 00:44:05][error] mysqldump: Got errno 28 on write

I'm backing up to S3, at least attempting to. The error above, especially the last line suggests a disk issue? If so, here is my partition break down:

[root@mysql0 ~]# df -h -T
Filesystem Type Size Used Avail Use% Mounted on
/dev/mapper/vg0-lv0
ext4 5.7G 3.7G 1.7G 69% /
tmpfs tmpfs 7.8G 0 7.8G 0% /dev/shm
/dev/sda1 ext4 485M 53M 407M 12% /boot
/dev/mapper/vg1-lv1
ext4 2.0T 694G 1.2T 38% /mysql

Is it possible backup is creating temp files on the small (OS) partition? If so, is there a way to specify the correct path?
