Hi I would like to Backup actual values of DBs .

Does someone knows a easy way to do it ?

Thanks.

I figure out you talk about S7 block. In manager, open your project offline and online (2 windows), then you just have to drag and drop the data block you want to backup. You will keep your comment and symbol, take care : if you upload data block you lost symbol and comment.

to avoid loss of symbols' name you may take a look at the DB RAW DATA utility at runmode.com

With the method in previous post, you'll not loss any symbol or comment.

yes, your method is correct indeed.
I just want to inform that it works only if the online DBs have exactly the same variables declaration and format of the ones in the offline project.
In case you have differently formatted DBs (it may happen), the S7 editor will mess up the var names.
