I'm just with a simple doubt. My files of backup are variating in weight... sometimes they get lighter then the previous one. Is it a problem? or just compression?
If my backup is broken, will i see the site as usual with a problem in some part or will i have a big white screen describing errors in database? that is: is it ok if my backup is as expected in a single page? or is there a possibility of my site to get a problem only in some pages?
