Requires separate Webmin backup!

• Backups require free space in /tmp
• Estimate the amount of temporary space needed by the size of your largest Virtual Server
• Choices for disk space:
  • Make sure the installation partition with the root filesystem has sufficient space
  • Extend the installation partition and root filesystem
  • Change the temporary folder used to one with more space
  • Add an additional disk/partition and mount it on /tmp
    • chmod 1777 /tmp
• Scheduled backup jobs can cause disruptions of hosted services
  • Prioritize CPU utilization of scheduled jobs (nice level)
  • Prioritize IO utilization of scheduled jobs (ionice level)
