I have a question and a comment. When I use # systat -h iostat I get the following display: DEVICE READ WRITE RTPS WTPS SEC sd0 39M 819 6803 0 1.0 sd1 0 40M 0 641 0.3 Totals 39M 40M 6803 641 1.2 What does RTPS and WTPS mean? I am using OpenBSD 7.3 GENERIC.MP#3 amd64. I dump with the following command: dump -0au -f /mnt/OpenBSDHome-lvl0.dump /dev/rwd0g /dev/rwd0g is /home. I get thes results: DUMP: Date of this level 0 dump: Fri Sep 22 20:50:47 2023 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/rsd0k to /mnt/OpenBSDHome-lvl0.dump DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 30528073 tape blocks.

I don't think that is bad at all. It's dumping /home to a USB external hard drive. The dumped machine is a Lenovo T440 Thinkpad with Softdeps enabled, on an SSD drive. What do you folks think? -- Kind regards, Jonathan
