[HECnet] A2RTR downtime

[Thomas DeBellis]

Thanks, I'll go have a look.

I was thinking about the duplicity utility, but I didn't feel like 
learning it or relearning tar and friends.  Really, the only time I want 
to be bothered with Linux is either when somebody pays me to look at it 
or I need to fix (or enhance) something in KLH10.

What I would be doing would be backing up everything _except_ the 
Tops-20 disks.  The two reasons for that is that a native backup gets 
you a consistent save set as opposed to a bit being in the wrong place 
in the file system when grabbing data from the 'raw' disk.  Further, it 
enables me to find and fix bugs with the Tops-20 Backup/Archive utility 
(DUMPER), fixing Tops-20 bugs being my odd idea of fun.

Right now, I've encountered the situation that previous versions of save 
sets appear to always set the SECURE bit, which is not something you want.
