We have been down for 6 minutes and 15 seconds, in that time I installed a usb2-pci-adapter. I'm sure nobody missed us. I had been testing the backup2 contrib in combination with an external usb disk. The backup works fine, but usb 1.1 is real slow, it took more than 16 hours for a complete backup. Now the external disk is connected through usb 2.0. Testing with hdparm, I get a throughput of 19 MB/sec.
