Making a backup of а web site is a common task.
The benefit of doing a backup is that you have 100% working copy of the entire web site. You can restore it any time in case you or someone else mess up something on the site.
In case you need to update the site with newer version of SEEEEMS it is strongly recommended to have a working copy.
There are many ways to make a backup of a website.
One of them is to create an archive manually.
In SEEEMS.CMS we have a Scheduled Services and with them you can make a scheduled backup of entire website.
You can learn how to set up a scheduled backup in Scheduled Services article.
