I would like to get 7-Zip Manager to zip my wwwroot folder on a weekly basis. Is it possible to automate this with Windows 7 Task Scheduler, and if so, what are the exact steps to do this?
You would need to create a Windows Batch file that will do that actually ZIP, and then schedule this in Task Scheduler to run on a weekly schedule.
The 7-Zip command-line samples are available here and a step by step guide to Windows 7 Task Scheduler is available here. Lastly to create a batch file use notepad and create a new file with a .BAT extension as follows
@echo off [7zip command line here]
Save the file somewhere on your drive and point the scheduled task to it. Complete details on batch files are available here.
