First backup long time after update latest patch?

Post by frankive »

After applying the two latest patch (a and b, .2029 and 2030) I have seen that the backup job will take quite long time. Almost like a Active Full backup but still just transfer the incrementals.
This results in that the backup window is not large enough the following day after we apply the updates.
This behaviour is seen on many installation, is there something I am missing I should be aware over? Is it a kid of reset of CBR?

Frank, this is caused by the fact that CBT driver is updated and full read of VM data is required.
