If the app.backup_dir property is not mentioned, the current working directory is used to store the backup files (.tar.gz files)
The database backup is only supported for the MySQL database.
Database backup uses the command/binary mysqldump and requires the command to be available on the same VM as the application VM.
The data directory and database backup are tar'ed and gzip'ed into a single file using the following format - yyyyMMdd_HHmmss.tar.gz
Email notification is sent to IT admin and super admins when a backup fails.
Only last five backups will be retained.
If we take six backups in a single day then only latest Last five backups will be retained.
