Ha!! Snap! I have recently mailed the Redhat linux and openssh development
list about a similar problem. I'm using openssh 2.1.1 from a RH6.1 linux box
being backed up to a Sun Ultra 10 (Solaris 8). It takes 8hours overnight to
backup 2GB. During the day it does it in about an 1hour. Throughput is
attrocious - about 75KB/s at night; about 750KB/s during the day. Also while
the PC is being backed up during the day I'm still using it fine -
reading/sending email, running X and Netscape, etc. No problems.
However, I have no idea why :-( I have run top overnight on both systems and
nothing unusual happens - no other backups, no jobs suddenly kicking in (I
disabled the linux cron.daily). The Sun is 'busy' in as much as %idle never
seems to get much above 60%, and the %kernel and %nice (I think) seem higher
than I'd expect, but it still doesn't explain why the backup runs fine
during the day but takes over 8 times as long at night. (Sorry I've deleted
the log file I had the data in.)
No-one else seems to have too much idea about it I'm afraid. I am tonight
backing the PC up onto a sparcstation 20 (Solaris 7) to see what happens.
That machine has no users except me - but the Ultra 10 had no users either.
If it's not the machines then it must be the network - but overnight? Weird.
John.
