Time Machine

Tonight I added an additional external disk to my Time Machine managed backups. This leaves me with the following configuration:

• Drobo with 2 * 500GB HD acting as the Time Machine Disk
• 250 GB Internal being backed up by Time Machine
• 2 * 250 GB FW External Drives being backed up by Time Machine

After adding the second external drive to the Time Machine Backup I kicked off a backup manually. I proceeded to ignore it and do some coding. After a few hours it hadn't completed backing 40G of data. I did a rough calculation and it was averaging aproximately 300-400 kBs. Needless to say that's is quite disappointing. At first I suspected the Drobo. (I'll admit I'm not a USB fan.) After some searching I realized it probably wasn't the Drobo.
