Which OS?

I have a new backup script that stores textdb's by default.  It is
much much improved over the old one--it has the option of storing
textdb or binarydb, and of compressiong with any number of compression
tools (bzip2, gzip, compress), or not compressing at all.  Like the
old one, it is implemented in perl.  I have only tested it in FreeBSD.
You can grab it at:


Feel free to use it and let me know how things go.  I have been using
it with tCD for a few weeks now, with textdb storing and bzip2
compression.  The only thing that should be noted is if you get a
corrupted DB, it will no longer store the backup, so having a script
that watches the genesis logfile for failed decompiles is strongly
recommended (infact I may change the script to email when it has
problems of this type).
