Compress backups while doing
Actually backups are compressed at the end. My uncompressed backup is 1TB, compressed is just 200 GB, but I still need 1 TB of free space for backup to be performed.
In Plesk 12.5 backup data compression is performed during backup, not after or at the end.

As I can see now your issue is about not accurate calculation of needed disk space amount. Our engineers will continue the conversation in ticket #2043179
Thanks for your patience.

I can confirm it is not working. See ticket #2043179.
With incremental backup and option "Start the backup only if your server has the sufficient amount of free disk space (this option may significantly increase the backup time) " my server will not start the full backup because it pretends to have 1 TB of free space (my content is 1 TB), while the resulting compressed backup is less than 300 GB (uncompressed is 1 TB in effect).
