Split backup files into parts (eg 250mb)

I am new to urbackup. Installed it two weeks already and loving it. The client/server idea is great!

I would like to know is it possible to have the backup file split into parts. Like how VMs or rar/zip splits it’s file size into multiple user defines size (eg 100m or 250m).

This is something important to me as I rsync my backup files into cloud. Having the files split into multiples of 250mb helps me to resume the sync in case the connection get broken while uploading.
