Hi
What is the expected difference in performance between rsync+shh and rsyncd?
I would use it over a private LAN, so no concerns about security.
Currently rsync+ssh is way too slow for a huge number of very small
files (about 700K email files in an imap server tree), even without
--checksum.

Following this hunch I tried starting the BackupPC_dump
Hi Pim,
using jumphost here for backing up a remote host and it's VMs without any
problems. What BackupPC version do you use?
I am using BackupPC 4.3.1-3 from the yum repository for CentOS 7. Very good to
hear that you got it working on your installation.
ok, so I'll try it on an 4.3.2

What version of BackupPC are you running? 4.x will likely be a good deal
faster than 3.x for both rsync+ssh and rsyncd.
The penalty of rsync+ssh vs rsyncd is likely modest, although it depends on
how much data is changing between backups.

like 75MB/s, nearly saturating a gigabit link. It seems you have basic
filesystem performance issues. More RAM, larger caches, SSD?

Thank for the suggestion. Unfortunately it's not SELinux, I have it fully
disabled to be certain.

I have 3.2.1 backing up this imap folder.
I'm evaluating whether to upgrade to V4 but I am mirroring

You seem to have a pretty good handle on stuff, but you aren’t suffering from
CentOS’ silent killer are you? SELinux?
Thanks,
