using planned failover is a nice thing - I was using it many times for maintenance windows in the past, but it took a while to have those two replication passes gone by until the vm got started (which took some minutes in my case and so it wasn't a "clean" transition).
Now CDP failover itself has some offset in terms of replication due to the fact that you're not replication every millisecond, so you might loose a bit of data one you failover. That's why I was curious to see how the planned failover works and I did a small test. I saw the following (shortened):
- vm was shut down
- creating long-term restore point (+34 sec)
- starting replication (+20 sec)
- failing over (+20 sec)
WOOOOOW!!
So doing a planned failover here is done in a bit more than one minute (and this is for sure not the fastest hardware in the world) - that is fantastic! Very well done veeam, thanks very much, what a great product!
