[Samba] Samba backup script retention question

[lingpanda101]

Hello,

     I'm using the 'samba_backup' script with the self compiled version. 
I noticed the retention period not being applied to etc and sysvol 
tar.bz2 files. Looking at the script it appears to only list the 
following at the end

'find $WHERE -name "samba4_*bz2" -mtime +$DAYS -exec rm  {} \;'

Can I also include the etc and sysvol tars in the command? Any reason I 
shouldn't if I need to restore? Thanks.
