Backup Script in Linux

Backup Script in Linux

Script for taking backup of logs stored by syslog-ng at folder "/var/log/HOSTS" & "/var/log/Firewalls" to a backup folder "/var/log/backup" as defined by you and then removing the original files for accommodating more space. Backup files will be generated with the time stamp and zipped to the backup location for easy searching and saving space.

Script will run every morning at 08:30 AM with the help of cron job.
