Thanks,

  I'll take a look at this script, hopefully later today.

  I'm already running full backups on a daily basis (to two different

  learned to be paranoid); If I request that my colleagues keep their
working copies
  around for at least 24 hours after a commit, I should be be safe enough.

thanks for your time,
