Re: [foxboro] 51 series remote backups

Awhile back, I experimented and created what appeared to be a valid backup 
by making a change to the dd command that backs up the raw partitions.  I 
haven't had access to the required equipment to confirm the backup, but 
the change looks something like the following:
Original Command - 
  dd if=$RAW_IFMX of=/rem/$dump_host$NTAPE_DEV bs=96b

Altered Command - 
  dd if=$RAW_IFMX | \
  rsh $dump_host "dd of=$NTAPE_DEV bs=96b"

Being risk adverse, and wanting to use methodology fully supported by our 
vendors, we too are investigating how to better accommodate local backups. 
 Many of our workstations have limited rear access, so we may simply 
purchase dedicated cabling and any required SCSI terminators for each 
workstation.

Shut the machine down to single user mode, (Foxboro came out
with a sheet on how to do this the 'right way' in the last few
months.  I can try to dig this up if you need it). Then run:

/usr/local/backup <tape dumphost>


Note however, that backing up over the nodebus is not a good
idea.  It seems to work with the older WP's, but with the
newer WPs, it will overload the nodebus - DM's showing
smurfed numbers, etc.  If you want to do it over the network,
do it over the 2nd ethernet port.  With some of our later
WP51F boxes, the backup script (provied by Foxboro) was set up
to try to rmount the dumphost. However, rmounts don't work over the
second ethernet port. Since it wasn't needed to complete the backup,
as the WPS didn't have the informix partition that uses the rmount,
that got taken out of the script.
