Every day I m running my daily cron backup, I noticed that at the end of the backup procedure my server goes offline for about 2 minutes. This happens every day.
Server details: Intel® Core™ i7-920 Quadcore incl. Hyper-Threading Technology RAM: 12 GB DDR3 RAM Hard discs 2: x 1500 GB SATA-II HDD (Software-RAID 1)
Keep in mind that I only host 40 websites that use only a fraction of the servers resources.
Backup is scheduled early in the morning were traffic is minimum.
