Thanks, had re-read the man page and I am able to test also using the -in dry run option.

I assume rsync will do a full-on sync between the source and destination. Quite embarrassing, I should have known it will consider the source as the 'master' and the destination as the 'slave'

Anyway, I am using rsync with the -niazv option and it starts as below:

Code:
sending incremental file list
.d..t...... ./
<f+++++++++ testdb_1_1.dbf

Do you know what the .d..t...... ./ mean? Just curious, whether it means this is the root/parent directory and it is skipping it?

rsync_selinux(8)					rsync Selinux Policy documentation					  rsync_selinux(8)

NAME

       rsync_selinux - Security Enhanced Linux Policy for the rsync daemon

DESCRIPTION

       Security-Enhanced Linux secures the rsync server via flexible mandatory access control.

FILE_CONTEXTS
       SELinux	requires  files to have an extended attribute to define the file type.	Policy governs the access daemons have to these files.	If
       you want to share files using the rsync daemon, you must label the files and directories public_content_t.  So if  you  created	a  special
       directory /var/rsync, you would need to label the directory with the chcon tool.

       chcon -t public_content_t /var/rsync

       To make this change permanent (survive a relabel), use the semanage command to add the change to file context configuration:

       semanage fcontext -a -t public_content_t "/var/rsync(/.*)?"

       This command adds the following entry to /etc/selinux/POLICYTYPE/contexts/files/file_contexts.local:

       /var/rsync(/.*)? system_u:object_r:publix_content_t:s0

       Run the restorecon command to apply the changes:

       restorecon -R -v /var/rsync/

SHARING FILES

       If  you	want  to  share  files	with multiple domains (Apache, FTP, rsync, Samba), you can set a file context of public_content_t and pub-
       lic_content_rw_t.  These context allow any of the above domains to read the content.  If you want a particular domain to write to the  pub-
       lic_content_rw_t domain, you must set the appropriate boolean.  allow_DOMAIN_anon_write.  So for rsync you would execute:

       setsebool -P allow_rsync_anon_write=1

BOOLEANS

       system-config-selinux is a GUI tool available to customize SELinux policy settings.
