Creating TAR file of home directory .. .. TAR failed! cat: write error: No space left on device

Hello,

we have a problem with backups to FTP server. In attachment i send df -h list from command shell on webmin. I also tried to change TMP folder (tried /var/tmp ; /home/tmp and /dev/tmp) but nothing helps (also tried to delete .webmin file from tmp folder).

Backup failed! See the progress output above for the reason why. Total backup time was 31 minutes, 08 seconds.

Virtual servers that failed : mpv.intebo.cz Sent by Virtualmin at: https://linux02:10000
