The Rate lines give the dump speed from client to tape server and tape writing speed, all in KBytes per second. Failures and unexpected results are detailed here. Informational notes about the run are listed here. The rest of the notes say taper was not able to write as much data as it wanted, probably because of hitting end of tape. Up to that point, it had written 19567680 KBytes in 90 files on tape Daily-009.
Entries are in alphabetic order by client and then by area.
This is not the same as the tape order. Tape order can be determined with the find or info suboption of the amadmin command, amtoc can generate a tape table of contents after a run, or amreport can generate a printed listing. By default, client names are truncated on the right, area names on the left, to keep the report width under 80 character. This typically leaves the unique portions of both. One is named amdump.
