Intra-Daily Frequency

Macrium Reflect v8.0 now includes Intra-Daily scheduling of backups for a minimum of 15 minute intervals between start times for selected days. 

Note:  Intra-daily schedules in the 'Scheduled Backups' tab will show the task description as provided by Windows. This will be localized and shows the start time and duration rather than the end time:

e.g.,  Every 15 minutes from 09:00 for 8 hour(s)

We are aware of this issue and we're considering options to overcome the inconsistency.

We've also added an 'Intra-daily Backup Set' Template to assist with setting up common use cases for this new scheduling frequency:

The default template defines the following backups:

  • Full at 09:00 on the first Monday of each month.
  • Differential every weekday morning at 09:00
  • Incrementals between 09:00 and 17:30 every weekday. 


  • Retain 12 Full backups
  • Retain 4 Differential backups

Intra-Daily Stealth Mode

Note:  Intra-Daily scheduled scripts, PowerShell, VB-Script or MS-DOS Batch files, must be regenerated to be compatible with Stealth mode. An extra parameter is passed in the schedule command and this needs to be processed by the script. 

Stealth mode is set by taking 'Other Tasks' > 'Edit Defaults' > 'Advanced' > 'Intra-Daily' 

Intra-daily backups can generate frequent and often unnecessary interruptions and log activity. Stealth Mode solves this problem by suppressing non-essential notifications and logs:

Suppress the Backup Start dialog.

Never show the Backup Start dialog that is shown when a scheduled backup is triggered. 
Note:  This overrides the default setting for the dialog. 
Only show Failed, Cancelled and Warning completion notifications.Taskbar popups and notifications will not be shown for successful backups. 

Only generate essential logs.


Logs will only be generated for Failed, Warning or Cancelled backups, and File and Folder backups when any file is changed, added or removed. 

Note: To mitigate against the possibility of missed backups going unnoticed,  a future release of Macrium Reflect will include a daily summary exception to compare expected schedule backups with a daily summary of backups run. 


Intra-Daily Stealth mode is enabled by default, and if an Intra-daily schedule is selected then the following dialog is shown:

Click 'Stealth Mode Settings' to open the defaults dialog to change or confirm. 
Select 'Do not show this again' to stop this message being shown in the future. 
You can re-enable by taking 'Other Tasks' > Edit Defaults' > 'Advanced' > 'Miscellaneous'
