That's how long it took. To backup a week's work of changes with Tivoli Continuous Data Protection. In my last post on Tivoli CDP, I hadn't configured a remote backup.
I configured one using an old 30GB IDE hard drive with a USB 2.0 adapter. It took a couple of hours to synchronize the first time and then I removed it. I threw it in my trunk to keep it separate from the PC.
Each weekend, I bring it in the house and plug it in. This week (a typical week), it took 90 seconds after Windows recognized it to completely synchronize with Tivoli CDP.
