My boards are 6.7.0

Each month I zip the entire CGI directory structure, and copy the file off the server - I've been watching the disk utilization grow for some time now - today at 300+ MB on the server - it zips down to about 80-120MB - but that also varies wildly month to month. ??

My questions - is it normal to be at 300+ MB on the server? (175,000 + Posts, VERY busy on a daily basis)

Anything I can / should be doing to keep disk under 'control'? ( mine is a dedicated server with over 20+Gb of disk, so I have A LOT of room to grow)

Compression ratio - are they consistent? I mean, when I zip down to a 120MB file, does that mean my disk was over 400MB?

I recall starting with the UBB reading 100 (or was it 150?) MB was all that would be needed?

No problems - it is all working very well, but I was wondering..
