How To Do a Hot Backup for Linux

How To Do a Hot Backup for Linux

Note: Users of EBI 3 for Linux looking for back-up instructions, can review the following:

Below is the shipped backup.sh script. This script can be executed from Linux cron or within the Business Process Scheduler.
By default the backup directory is EBI_HOME/database/backup.
If users want to change the script, it is recommended that they copy the shipped copy. One update would be the target directory, then update the DB_FOLDER_BACKUP variable.
To run the command: Execute backup.sh -online or backup.sh -offline
