[CentOS] SElinux suggestions needed: migrating backup service

Hi folks,

normally I have not so much to do with SElinux but I expected to get in touch sooner or later :-)

I migrated a backup-system from El5 to EL6 and the rsync backup process is complaining about selinux attr's now. 

client <-> server (fetches via rsync -aHAX)

client# sestatus 
SELinux status:                 disabled


server# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   permissive
Mode from config file:          permissive
Policy version:                 24
Policy from config file:        targeted


for example, no label for this file on client side: 

client# ls -laZ /usr/share/zoneinfo/Africa/Bissau 
-rw-r--r--  root root                                  /usr/share/zoneinfo/Africa/Bissau


but on server side: 

rsync: rsync_xal_clear: lremovexattr("usr/share/zoneinfo/Africa/.Bissau.WaE4wj","security.selinux") failed: Permission denied (13)

and 

server# ls -laZ /BACKUP/usr/share/zoneinfo/Africa/Bissau 
-rw-r--r--. root root unconfined_u:object_r:locale_t:s0 usr/share/zoneinfo/Africa/Bissau


the local (server) destination is mounted like:

server# cat /proc/mounts |grep BACKUP
/dev/sdc1 /BACKUP ext3 rw,seclabel,nosuid,nodev,noatime,nodiratime,errors=continue,acl,barrier=1,data=ordered 0 0

this partition comes from the former system (EL5 productively used without labeling it and with SElinux disabled).

I started to enable SElinux (permissive) on new systems and therefore disabling SElinux 
like it was done before on the former system is not an option.

Any suggestions to avoid the default labeling "unconfined_u:object_r:locale_t:s0"?
