How to reduce Backup Space

Thread needs solution

I've got a backup 230 GB (1 Full and 20 incremental vers) on a 500 GB Disk.
My Goal is reducing the Backup Space and delete some older Versions for example the
5 oldest incremental versions.
is that possible?

All incremental files are necessary for a full restore. You have therefore to set your task to create fewer incrementals.
Option A (recommended) is to set it up as an incremental task and to limit the number of incrementals before a new full. Then set it up so that you keep only the 1 most recent backup chain. Careful! You need to make sure that you have enough space to create a second full backup on top of your first + incrementals, because ATI will always create a new full backup before erasing any previous chain (full + incrementals). A way to circumvent that policy is to erase all the files before the task starts by creating a pre-command of the backup task. When ATI starts a task in am empty folder, it will always create first a full.

Option B (not recommended) is to set it up to do always incremental, but to use consolidation to limit the number of incrementals. Unfortunately, consolidation is a lengthy process, requires a lot of space (because the consolidating files are copied in a temporary file before replacing the originals) and it will have to run every time you backup after the number of incrementals triggers the consolidation setting.
