Due to problems in bash (or my scripting knowledge) I was having ongoing problems with spaces in the directory names. I decided to convert the shell script to a wrapper to launch a perl script that actually calls rsync. The shell wrapper still handles compressing and deleting old logs.
#!/bin/bash
declare LOGDIR="/home/backup/logs"
declare SCRIPT="/home/backup/scripts/backup.pl"
declare DATE=`date +%Y%m%d`
[ -d $LOGDIR ] || mkdir -p $LOGDIR
[ -x $SCRIPT ] || \
{
echo "ERROR: Missing $SCRIPT"
exit 1
}
##
## Call our perl script to handle the dirty work
##
$SCRIPT $LOGDIR >> $LOGDIR/backup-$DATE.log 2>&1
##
## Compress logs after 5 days and delete logs after 6 months
##
find $LOGDIR -type f -name \*.gz -mtime +180 -exec rm -f {} \;
find $LOGDIR -type f -name \*.log -mtime +5 -exec gzip -9 {} \;
