Methods of Performing Incremental Backups

After onQ performs an initial snapshot of your protected nodes, onQ performs incremental updates from that point forward. onQ can employ one of two scan solutions to achieve this goal: Filter Driver or Non‑Filter.

During enrollment, the Protect Me wizard installs the onQ Filter Driver, but it is disabled by default. If you want to choose this solution you must enable it.

onQ Filter Driver enables faster and more efficient incremental updates. The onQ Filter Driver is no different than the filter drivers that Windows backup products use. The major difference between the onQ Filter Driver and Non‑Filter is that the onQ Filter Driver installs as a service on the protected node, using some system resources.

Though you don’t need to know the “ins and outs” of each solution, you do need to understand when each performs optimally, so that you can choose the right solution for your organization:

Circumstance	Recommendation
	onQ Filter Driver (Optional)	Non‑Filter (Default)
PN stores a large number (millions) of files
PN stores large files that change frequently
PN files don’t change frequently
PN stores a small number of files
PN has resource constraints (memory, CPU, disk space)

To enable the onQ Filter Driver:

1.	Log on to the HA Appliance’s onQ Portal.

2.	Stop protection.

3.	Go to PROTECTION CONFIG tab, select the protected node, then click MODIFY > ADVANCED.

4.	Select the Enable Filter Driver? Yes radio button, then SAVE.
