linux - split scp of backup files to different smb shares based on date -

i backup files tar files once day , grab our ubuntu servers using backup shell script , put them in share. have 5tb shares can have several.

at moment need more backup 30 days worth of tar files.

i need method first 10 days go share one, next ten share tow, next 11 share three

currently each server vm runs following script backup , tar folders , place in folder ready grabbed backup server

!/bin/bash  appname=myapp.com  dbname=mydb  dbuser=mydbuser  dbpass=mydbpass  datestamp=`date +%d%m%y`  rm -f /var/mybackuptars/* > /dev/null 2>&1  mysqldump -u$dbuser -p$dbpass $dbname > /var/mybackups/$dbname-$datestamp.sql && gzip /var/mybackupss/$dbname-$datestamp.sql  tar -zcf /var/mybackups/myapp-$datestamp.tar.gz /var/www/myapp > /dev/null 2>&1  tar -zcf /var/mydirectory/myapp-$datestamp.tar.gz /var/www/html/myapp > /dev/null 2>&1 

i grab backups using script on backup server , put them in share

#!/bin/bash # # generate list of myapps grab df|grep myappbackups|awk -f/ '{ print $nf }'>/tmp/myapplistlistsmb  # each app in turn  appname in `cat /tmp/applistsmb`         cd /srv/myappbackups/$appname         scp $appname:* . done 

i know tough 1 need 3 shares ten days worth in each share

i not anticipate backup script changing on each server vm backs itself

only maybe grabber script puts dated backups in share on backup server

or wrong??

any great
