Purpose

By default, catalina.out file does not rollover, and with time it grows large. This script will be executed by a cron job, to tarball catalina.out file and empty the large file.

Solution

1. First, create the executable backup.sh file

   backup.sh

   #!/bin/bash
   #Backup catalina* in a folder /backups in user home
   SRCDIR="path/to/bamboo-installation-directory/logs"
   DESTDIR="/home/$USER/backups"
   DATE_WITH_TIME=`date "+%Y%m%d-%H%M%S"`
   FILE_NAME="Catalina-backup"
   BACKUP_FILE=$FILE_NAME$DATE_WITH_TIME
   TARGET="catalina.out"
   if [ ! -d "$DESTDIR" ]; then 
        mkdir $DESTDIR
   fi
   cd $SRCDIR && \
        tar -czvf $BACKUP_FILE.tar.gz catalina.out  && \
        mv $FILE_NAME* $DESTDIR  && \
        truncate --size=0  $TARGET >&2
   exit 0

2. Ensure the file is executable

   chmod +x /path/to/backup.sh

3. create a cron job to run the script

   0 0 * * 5 /path/to/backup.sh >/dev/null 2>&1
