[BackupPC-users] Extremely slow backups
2009-10-06 16:44:43
I'm seeing extremely slow backup speeds. Far slower than anything I'd
expect given our network layout.
We have gigabit connections and my network testing shows that we
average around 105+ Megabytes / second between the two machines. So
network throughput is definitely not the limiting factor.
Server/Client: 10.5.8 osx leopard
Rsync: 3.0.6
BackupPC: 3.2.0beta
I'm *only* backing up the /Users directory currently after noticing
exceptionally long backups for this client. The /Users directory is
only 386MB total.
So far, the backup has been running for 5 hours with cpu load rarely
bumping over 40%.
It seems to be hanging on a subversion repository. The repository is
only about 240MB in size, a du -sh on fsomerepo in the pc/client/f
%2Users/fusername/fsomerepo directory has gone on for quite some time
with no result.
There are no errors in the logs, here's the tail end of the XferLOG.z:
> create d 755 501/20 170 jameskyle/Projects/mports/svn/
> dports/python/py-utidylib
> create d 755 501/20 306 jameskyle/Projects/mports/svn/
> dports/python/py-utidylib/.svn
> pool 444 501/20 234 jameskyle/Projects/mports/svn/

> pool 444 501/20 436 jameskyle/Projects/mports/svn/

> pool 444 501/20 2 jameskyle/Projects/mports/svn/
> dports/python/py-utidylib/.svn/format
> create d 755 501/20 102 jameskyle/Projects/mports/svn/
> dports/python/py-utidylib/.svn/prop-base
> pool 444 501/20 59 jameskyle/Projects/mports/svn/
> dports/python/py-utidylib/.svn/prop-base/Portfile.svn-base
> create d 755 501/20 68 jameskyle/Projects/mports/svn/
> dports/python/py-utidylib/.svn/props
> create d 755 501/20 102 jameskyle/Projects/mports/svn/
> dports/python/py-utidylib/.svn/text-base
> pool 444 501/20 107%
it's been at that point for a good while, but it *does* seem to slowly
progress.
Thanks in advance for any suggestions/help,
