[BackupPC-users] Using NFS to increase backup speed
2014-10-16 08:28:15
Hi all,
I'm seeing network speeds at about 35-45 Mbps when using BackupPC and rsync
over ssh.
Running iperf below I notice the network should theoretically be capable of a
bit more than that. I understand that ssh adds quite a bit of bottleneck.
[root@titan ~]# iperf -c cyndane
------------------------------------------------------------
Client connecting to cyndane, TCP port 5001
TCP window size: 42.5 KByte (default)
------------------------------------------------------------
[ 3] local 192.168.0.8 port 51754 connected with 192.168.0.9 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 398 MBytes 334 Mbits/sec
[root@titan ~]#
Just to clarify, titan above is the BPC-server and has some local disk space
where the backup pool is. Cyndane is the host being backed up. Both have
gigabit-NIC's and a ditto switch between them.
After reading one of the answers at
<<http://serverfault.com/questions/377598/why-is-my-rsync-so-slow>>, I kinda'
wonder if the NFS-angle would work for use with BackupPC and how I would go
about it. Is the tar transfer method the only one supported by BPC if using NFS
for example?
Rsyncing a NFS-mounted remote host supposedly is a lot faster than doing rsync
over ssh.
Any thoughts on this?
Has anybody on this list maybe set up their systems using NFS and can share
their experience?
Thanks.
