Automatic consolidation creates a new archive with the data from the original ones and deletes the older incremental or differential backups
You can set consolidation to run automatically in Acronis Backup Server to comply with the quotas and time limits set for each profile
This article describes how to back up a virtual machine using Acronis True Image Echo and VMware Consolidated Backup
Acronis True Image Echo has the capability to consolidate backup files (create a consistent copy of archive while deleting selected backups)
When saving an archive to Backup Location the progress bar halts at 100% and nothing happens. There is a progress going on, you just need to wait until it is over
If there is not enough disk space reserved for Backup Location, you may receive the "Disk is full" error message when trying to manage archives in Backup Location
