Concurrent backup creation and ftp upload
It would appear a new update has changed the non-legacy ftp backup system to create all backups before attempting to upload them, instead of uploading each as soon as it's created, as it was doing before. While I understand that this may have performance benefits, it causes massively more disk space to be taken up on the local machine, since it must wait before uploading and flushing backup files. This has severe repercussions for customers already using more than half their disk space, and for hosts using a vz shared space environment.
I request that the choice between waiting until all backups are completed to upload, and uploading as soon as each backup is created, be given to us. Preferably as an option in the backup configuration in whm.
