What does GZIP Compression mean, and does it matter if I have it on or off? :oops:

This is used for database backup, if the database(sql) file that you backup is too big, this is what come in to compress and make it smaller in size, to use this your host need to support gzip, but even if you turn on and your host doesn't support, it doesn't matter.

this is not quite correct, gzip compresses the data as it moves back and forth from the server to the browser, it will help a busy large board move faster.

it is also a compression method that can be used for the database files to make them smaller like zip does.

So it doesn't matter if my forum uses it?

And can a GZIPped file be opened with Winzip?

yes, winzip will open them, it does it a little differently, it will ask you if you want to uncompress the file to a temp directory and show the contents, and you just say yes.

I was talking about the one in database backup, didn't you read.

yes I read it very well, he asked about the turning it on or off, the only place to turn it on or off for the board has nothing to do with the database backup .

well, there is the option to back it up with it or without it.

but that is not turning it on or off, that is in the admin panel for the purpose I mentioned.

and your post is combining the two functions in your description of what it does.


luck,

Alright, so for safety I should leave it off?

I'm scared I might blow it up. :?

ilt doesn't matter if it is on or off, there is no safety issue about it.

if you have a large , busy board like this one, it would help ease the strain on your server, if you don't , then it probably isn't necessary.

Hey, there's nothing to be scare off, if you turn either Gzip option on config page or database backup one on, it's still fine, even if your host doesn't support Gzip.

Not entirely true. Gzip is only a compression utility but it has not file archive feature (combine multiple files into one file). Tar is a file archive, but it has not compression mechanism. That is why the two are combined together to form what is called a tarball.

While Winzip can handle gzip and tar files separately, it can not handle the two methods together at the same time. Instead, it uncompresses the tarball first, creating a regular tar file, and then opens up the tar file.

did not know that, thanks, all I know is that when you double click on a gzip file, winzip opens a dialog box and asks do you want to uncompress it to a temporary directory and I say yes.
