Backups larger than 2gb
Is it possible to make a backup to disk using ontape that is larger than
2 gigabytes? I think I read that it depends on your operating system
and version of Informix. I'm using Solaris 8 with Informix 2000 version
9.21. Does this combination support huge ontape disk archive and log
backups?
Yes, its possible.
The TAPESIZE and LTAPESIZE will still defined as 2 GB but you need to
create a script that will manage the renaming of the 2 GB file and
pressing the ENTER key.
Below is the shell script that manages the continuous logical log
backup. If you want to test this script if it really copies the file
before the Press Any Key..., change LTAPESIZE to 20 MB.
Copy this file at $INFORMIXDIR/bin directory and chmod 700 autolog.sh
Usage: nohup autolog.sh [<dir-to-copy] >> /dev/null &
If you are satisfied with this shell scipt, inform me and I will give
you the ontape script to disk.

If the backup is a file, is it not possible to just set TAPESIZE to let's
say 10 GB and let the OS deal with it ?
We actuall had a backup of 6GB in a file, without palying with multiple 2
GB pieces.
