growisofs -dvd-compat -Z /dev/cd0 -J -R -r -V volume-name /path/to/data

-dvd-compat indicates that the disc should be finalized, so no additional data can be added
-r sets permissions to sane defaults that work cross-platform
-V creates a label on the volume, no more than 32 characters

If there are files bigger than 4GB, (or 2GB on an old OS) you are going to have a bad time. The largest file supported by ISO9660 is

There are many ways to do this, but here is a quick way to use wget. "-l 2" tells wget to only go 2 links deep from the URL provided, so if you need more, change that value.

wget -p -r -N -l 2 -nc --no-remove-listing -k -E https://www.example.com/

If you're archiving the site simply for future reference, it might be beneficial to remove large files. Such as anything bigger than 2MB.

find www.example.com/ -size +2M -exec rm {} \;

There is lots of great information about using exiftool at http://www.sno.phy.queensu.ca/~phil/exiftool/filename.html. The one I use to manage my photos is

exiftool -d %Y/%Y-%m-%d "-directory<datetimeoriginal" ./

Another pattern that I'm trying out, to play a bit nicer with image browsers. Puts all images from the same month into one directory, and prefixes the file name with YmdHMS_ to make sure chronological order is preserved.

I can honestly never remember the correct files for doing a rescan of a SCSI bus so I figured I'd post this here. This isn't rocket science, but is here for quick reference. This is confirmed to work on RHEL 5/6, CentOS 5/6 and OEL 5/6:

ADD NEW SCSI DEVICE (i.e. new scsi disk)

# for f in /sys/class/scsi_host/host*; do echo "- - -" > $f/scan; done

DETECT CHANGES IN EXISTING SCSI DISK (i.e. growing a hard disk in VMWare)

# for f in /sys/block/sd*; do echo 1 > $f/device/rescan; done
