RE: [cobalt-developers] restore problem on RAQ3

["Andy Brown" <andy.brown@xxxxxxxxxxxxx>]

Hi Tim, hate to be bearer of bad news, but ditch those backups done
using the GUI. I've ran into serious problems, and just search these
lists and you'll find lots of people in the same situation. There is a
bug when it comes to uploading large files via the GUI or even handling
the files with the built-in restore feature it seems.

I solved this as follows:
1) Install the CMU import/export utility from cobalt, which is a
CLI-based migration utility.
http://emea.cobalt.com/support/download/migration.html

2) Setup the method of transferring the backup files. I use a
network-mounted drive to send backups to because the servers are in our
data centre.

3) Write a shell script to do it all for you nightly, placing the script
in /etc/cron.daily/

Using the CMU import/export DOES work as I've restored/backed up our
RaQs a few times now without problems. However as with ALL developments
with Cobalt products you MUST test it on a non-live unit first, as it
may not go as predicted. We had to purchase an additional RaQ for this
purpose because I didn't trust the updates coming from Cobalt (and with
good reason if you browse the lists!, I'm a pure linux-ist so have a
good background on the linux o/s)


Hope this helps you out!
