Take backup after every 5 minutes

[nomi-ramzan]

Short form:
How can i take backup after every 5 minutes ?
Details:
Backup manager file-name template is like prefix-filename-date.type is it possiable to add time as well because i wanted to take back after every 5 minutes and backup-manager is skipping new files ( will come after 5 minute ) and logging file already exists, skipping.

Thank you
