add function to DB Backup module...?
Using Jamroom
It is probably a good idea.
As a suggestion, try this.
Create a directory called "Site Name"
Add a new folder by date: "04.28.15"
Create a folder called "back"
Copy your modules and skins to the back folder before you change anything
Then drag your "working files" into the date dir
This way you always have a backup of what you are working on and the current files easy to access. It also provides a history of changed files and backups. It is easy to roll back to specific date this way.
