According to the TrueImage documentation, it requires an amount equal to the largest backup in the archive. But I didn't find this to be the case when my weekly backup ran yesterday. Instead, it seemed to require an amount much larger than that, perhaps equal to space taken by ALL of my backups in the archive. But I don't know for sure, because I ran out of disk space and the auto-consolidation never completed. Can anyone shed some insight into this process?
