[clamav-users] A workaround for the major ClamAV DB update delays we have been experiencing

If you're looking at the CLD it will be bigger, because the CLD is not compressed and the CVD is compressed.  When you use diffs, it will store the database in CLD format.

I wonder if the file size changed when Joel regenerated the daily.cvd file  (or I had in unexplainable file size error). I still use all the technology but no longer for big dot coms. The patched files are larger because they have a lot of unneeded bits in them.

The daily.cvd is still less than half as big as main.cvd:

but indeed using the cdiffs could save bandwidth.

I never tried using cdiffs since the FAQ said "Let freshclam download
the *.cvd files", and I wasn't sure if "scripted update" would actually
create a proper cvd for both local mirroring *and* HAVP. Also, I
figured that we were already saving lots of bandwidth by doing local
mirroring instead of N separate freshclam external downloads.

P.S. After retirement there is less pressure, but the technology I deal
with daily (for my own purposes, rather than for pay) doesn't seem to
get any simpler.
