[Plugin: W3 Total Cache] How to "freeze" the blog for a long time

Unfortunately there’s no way to make the cache never expire, but you can set the expires value to a very large number if you wish. Cache priming allows you to automatically build the cache for your site even without visitors requesting the pages first.

You might would like to rethink twice before applying if there is any feature for cache never expires. This is because if your website might cache on the previous cache and keeps on showing the same content even if you have updated the contents.

Thanks for your answers. ??
