Hi,

Ok this version is a little more together, the report now includes  
the ability to create a report for a specified period.

The script can be run by hand with or without command line parameters  
(will default to the last found backup in the log file). Script does  
require ExtendedLogging = yes to get the data it needs.

Options are:

Usage: boxreport.pl [options]

Options:
    -l, --logfile=filename       logfile to read
                                 (default: /var/log/box)
    -h, --help                   Displays this message
    -D, --debug                  Sets debug mode
    -V, --verbose                Even more debug output
                                 (more output, but performance hit)
    --mail=emailaddress          Sends report to emailaddress
    --sendmail=/path/to/sendmail Location of sendmail binary
                                 (default: /usr/sbin/sendmail)
    --from=emailaddress          Sets From: field of email
    --start=01/01/1999           Report files from this date (optional)
    --end=31/12/1999             Report files to this date (optional)

Enjoy. Please let me know feedback good, bad or indifferent.

-- Chris I might try altering the code for the backup-client to call  
boxreport.pl if it finds ReportScript = /usr/local/bin/boxreport.pl  
(or similar) in bbackupd.conf  (if I can work out how to do it :-)  
that way I can get the the report to generate and mail right after  
the backup has completed rather than having to wait for cron etc.

Regards

Matt Brown
