Should I backup bmz_cache?

I just wondering when I am planning to run a site backup, should I also back up bmz_cache, because the file number and size is getting larger and larger.

thx in advance

Not necessary to backup these files. These image files are created "on the fly", so if an Image Handler generated image is not present, a new one will be created.

I occasionally delete these images if the folders get too full, and while this may slow things down a fraction in the short term, at least you're not occupying huge amounts of server storage.

I'd like to add a bit to Schoolboys comment.

It is for the most part true that the bmz images can be deleted with few or no ill effects. But, if your site displays many images (ie rows and columns) and the site is popular, re-drawing all those images can bring a wimpy server to its knees (or worse) as the cache is re-built.

thanks to your guys, it really helps a lot:smile:
