Re: [Fwd: Re: Automating Backup Verifies]

[Tony Dominick <dominica@xxxxxxxxxx>]

Hello to all in Innopac-land,

I heard that some were interested in my method for automating the step
that verifies the backups.  First a little background so you know where
I'm coming from.  Here at Drexel University we don't have a tape drive
attached to our Innopac server so we had Innovative make our back routine
place the backup file on the server's hard drive.  This in turn gets backed
up by the university's central backup server.  We have scheduled
unattended full backups to take place each night at 12:00 midnight.  Now
with this setup and running everything was automated except the "Verify
the backup" part.

To automate the the "Verify the backup" part I used a unix-like system,
the "crontab" task scheduler (that comes with most unix-like systems), and
the scripting language Expect.  They are all freely available from the
internet so the price was right for me.  Now I just look at the
"Unattended backup log" once a week to make sure everything is okay.  So
far a year has gone by with only one problem that Innovative was nice
enough to correct.

You can get info and download the Expect scripting language from
<http://expect.nist.gov/>.  Looking at this website I see that they have
Windows version of Expect available.  I've never used it so someone let
me know well it works.  I can recommend the book "Exploring Expect" by Don
Libes which helped me.  

Below is the Expect script that I wrote.  

Linda and Chris, sorry to keep you waiting, I have been a little busy.

HTH,
Tony
