I'm wondering if is there any possibility to track changed blocks in linux with an ext3/ext4 filesystem (or a specific one supporting it).I mean a feture like the Changed Block Tracking (CBT) available on ESX/ESXi systems. I refers to the feature discussed here:What is Changed Block Tracking (CBT)Understanding Changed Block Tracking on Virtual Machines.
Something like VMware Changed Block Tracking (CBT) in linux
