Yes, but it is possible to make a local incremental backup and then rsync it to the remote datacenter. It requires a lot of less bandwidth than if we have to transfer full backups every day to the remote data center.
I understand that Ayufan's patch is not the best option for incremental backups but I believe that, if there is no backup inconsistent data problem with it, is a good option until exists something better. What do you thing about it?
