Re: backup throughput



In comp.os.linux.hardware Hactar <ebenZEROONE@xxxxxxxxxxx>:

I've got a second hard drive, identical to the main one, onto which I
(nightly) duplicate the main hard drive, thus ensuring that I always
have a complete backup that is less than a day old.
[..]

4:31:43 throughput dropped from40: MB/s to ~34 MB/s. Apparently
something started then that used up the IDE or PCI bandwidth (dd isn't
very CPU-bound), probably something invoked by cron, as nobody should be
on the computer at 4:30. I'm guessing the mystery process runs after

Remote guess, updatedb fired up from cron.daily, check when and
what is launched from cron and the cron logfiles in addition.
There is no need to guess.

Good luck

BTW
I'd suggest looking into rsync/unison to mirror to the second
disk, this should be much more effective after the first run.
