Really important to use ddrescue and not rsync in some cases, because rsync's temp file should be tens of gigabytes larger but isn't. Where'd that data go!? I may have realized this in the past, weeks/months ago, but just forgot:

Temp file=21GB, should be about 100GB. (State=T=stopped - https://askubuntu.com/questions/360252/ - kill stopped jobs via "kill -9 ").
