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

CentOS’ silent killer are you? SELinux?
Thanks,

Hello 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

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

filesystem performance issues. More RAM, larger caches, SSD?

The penalty of rsync+ssh vs rsyncd is likely modest, although it depends on
how much data is changing between backups.

Following this hunch I tried starting the BackupPC_dump

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.
