Suggestion would be, don't put all your eggs in one basket. Check to see how
long, under normal circumstances, it takes before your logs switch. Or as
you stated in you e-mail select half hour. Stream a job which does a switch
log and then copies the log to another disc drive. A poor man's mirror.
Otherwise invest in Mirror/iX and mirror the info you want.
Redundancy is the only way to secure information. This was your suggestion
by attempting to send the data to a PC. Problem is you are going over a
network connection and using bandwidth, and have to come to the point of
having the network up inorder to get your data back. With an alternate drive
on same machine, the data is available as soon as the machine is up.

Subject: Image log files


Hi Folks,

After losing the sysdisc last week we have had some questions and discussion
about Image log files and how to save them.
Logging to tape is not practical an a pain in the.  Logging to disc is great
as long as you don't lose ldev 1 (as we found out the hard way).
So one idea we came up with to use FTP to copy the log file to a PC on the
network every ½ hour. While this does not save all your info losing a ½ hour
is better than loosing 8-12 hours work.
Any body want to shoot holes in this method or come up with another (disc
raid excluded) please do so.
I though that there might be a product available that would copy records
from the log file to a PC backup file as they are written but could not find
any (any takers out there).
While I would not bet the farm on a PC it might be a cheap way to save us a
lot of time and trouble.

Thanks for the time and input
