Using phy: or file: I can restore 600GB with no problems at all. With
tap:aio it crashes after a few tens of GB.
Another guess then... tap will probably have more outstanding
transactions than back as its datapath is likely to be longer and so is
higher latency. Is your frontend overflowing a queue of outstanding SRBs?
