Differential
When booted from WinPE-based Acronis Bootable Media Acronis Backup & Recovery 10 always creates full backup archive instead of incremental or differential

By deleting the ".meta" folder you remove the meta information about the backup
Automatic consolidation creates a new archive with the data from the original ones and deletes the older incremental or differential backups
Acronis True Image Echo has the capability to consolidate backup files (create a consistent copy of archive while deleting selected backups)
How to consolidate backups manually and how to set up automatic consolidation
This is a known limitation
