The repeated "DUMP: " in the 9th last and 4th last through 2nd last lines
shouldn't be there.

I am also curious about the time estimates.  It was a dump over the net and
to a disk file.  The partition size didn't change by more than a kbyte
during the dump.  Is the percentage calculation done on the basis of size
or of time elapsed?  I can see the time estimates being off due to varying
network throughput, but they should never be negative.  Clamp them at zero
or print question marks if no good estimate can be made (or heck, give a
standard deviation for the uncertainty of the estimate ;-).  The percentage
is downright strange, as df reports the same number of used blocks before
and after the dump.  Is something wrong, or is it just a byproduct of
varying net speeds?  If I were to do this calculation, I would be using
bytes transferred/total bytes, and the numerator would never get 10% larger
than the denominator on a 1GB+ filesystem whose size didn't change.  The
dump file is 5% larger than the filesystem's df size.  I don't see similar
estimation problems on larger partitions of the local machine.


Comment 1 Stelian Pop 2000-03-11 16:08:59 UTC
The repeated DUMP: DUMP were fixed in 0.4b16.

The negative time estimations were fixed in 0.4b15.

The calculation method is indeed using bytes transferred/total bytes. Except
that the total bytes are based on an estimation made at the beginning of dump,
and this can be wrong, even if the filesystem is quiet. (since the estimation
must be quick, so the estimation algorithm doesn't take into account all data -
see the changelog for 0.4b16 for details).

But the estimation algorithm was improved a bit in 0.4b16, so the results should
be more accurate now.
