If you have checked disk I/O, CPU, memory, network, on both the client
and the server, all seem great, both from a statistics look, showing all
running normally, with low use. Verified with read/write test on local
disks, remote through he network, using regular file copies (via SMB)
and iperf on both client and server. However my backups which ran last
weeks full backup in 3.5hrs at 26mbps, are now running at under 4mbps
for this week. I have stopped and restarted things, no change. Every
test I can think of shows everything is running great, but the backups
are going to take more than a day at this rate. This isn't a new setup,
I have been doing this for some time, using the same server / client
combination. The only other client on the server ran normally, but it
uses gzip (the one running slow doesn't) and never ran faster than about
6mbps, with between 55-65% compression. The local catalog backup ran at
60mpbs, which is almost as fast as dd if=/dev/zero runs against the
drive I write my backup volumes to, as the dir and sd are on the same
machine.
Could I possibly be having a Database issue, I am using PostgreSQL,
that could cause this, possibly waiting on records to be written to the
catalog? If so how could I find out? Anything else anyone can think of
to check?
