I am doing really huge syncs between two harddisk (for backup reason). Besides this takes a lot of hours there is one point that strikes me:
Even when I push the PAUSE button in the sync window the dopus still eats 100% of cpu time. Even the memory consumption is increasing during pause mode. Dopus eats about 280 MB of memory.
Additionally either dopus freezes when switching from "copy from source to destination" to "delete from destination" or I am not calm enough to wait a long time. Is there a longer wait "scheduled"? Until now the process hangs for about 45 minutes.
The windows says under ALL FILES:
Cpu-Usage is 100% but the harddisks are silent.
I know that the same procedure worked some time ago.
Have you tried it with different directories on different drives? Maybe there is something particular about the combination of directories (the devices they are on, the number of files, the actual files in them) which is causing the problem? We'll need to narrow it down to a trigger as it's definitely not normal for the sync tool to behave as you're seeing.
