How long do you suggest I wait before deleting backup files?
Thanks, John

Some people will say 3 days, whilst other will say 3 months so it's up in the air as to how long you actually want to keep them, i.e.; it's your choice.

In reality they are relatively small unless a plethora of fixes took place, such as on a system that has never had the registry cleaned. You could even ZIP the backups to reduce their size for keeping them longer.

Keep them so long that you can really tell all works fine.

Thanks for the info. I figured I should save them until I was sure all was fine. I just like to keep things clean.
