Thanks. I previously downloaded those. IIRC, the "IBM" one says that it is an upgrade and one needs DLA to already be present. The "Dell" one says that it is a preproduction release and dire consequences are possible. I'll investigate the "IBM" version more fully. I wouldn't dare put the "Dell" one on a critical production machine.
I do NOT rely on on the CD-RW backup over the long term. It came in handy once when I was laid up in the hospital and the non-computer-savy employee could use my backup system to produce a CD-RW of January 1, 2007 data.
My normal backup scheme manually produces a backup on flash drive, a network transfer to another computer and two copies of the backup on CD-R. One of the CD-R copies is kept off-site. So there are five (5) copies of every backup.
Yesterday I enhanced my backup program (in C) to automatically write a flash drive. Each of these backups includes the date in the file name (automatically), so multiple backups can be made to the same medium without earlier versions being overwritten.
