Default ZIP with low priority

Greetings.


I'm creating an automated backup utility that would perform copying with data compression in ZIP format.

The thing is, I wanna run it with a real low priority, so that users don't have lack of performance during backup procedure.

Already tried Abbrevia component with low prio setting, but it just occupies available resources, not keeping it down at the minimum.

My question is - do you have some experience with compression components that would keep their work at low priority ?

Default RE: ZIP with low priority

You may use any compression component.

All what you need is to compress in thread and to define the low priority for your thread:
yourThread.Priority := tpLowest
or
yourThread.Priority := tpIdle

The correct way for doing such things is to use multithreaded application

This way you can not only set the required priority level (at thread level and not necessarily for complete application).

If you need to learn as how to do multi threaded programming with Delphi then you can use following wonderfully simple example:

also There is another example available which can be of use to you because it searches for files and creates their list in recursive manner:

Hope it helps and if it does then do accept the answere
