You show us a script, but you don't say what its name is. its a script called manually: backup.sh (If it is uvsh and you have multiple copies of this script running at the same time The multiple instances of uvsh appear from running the script, but I'm unsure of its relation nor should it happen? I am unsure , it is no wonder that you're having problems.)

If uvsh is something else and it is accessing your database while you suspend, validate, backup, and release it by running this script; that probably isn't good either. I unload the database which should close it to be tar'd based on eclipse's recommendation

What type of system are you using? What type of shell is /bin/sh on your system? (Is it a Bourne shell, a Korn shell, a Bash shell, or what?)
Redhat, bash, is that an ok answer?

When you watch this script run, what messages do you see (and does that tell you what portion of the script is running slowly)?
The script messages seem to function normally and in the past created a 15gb archive of the required back'd up folders, now it is not and I'm stumped

I have very limited basic skills in bash scripting.

I appreciate your reply and hope I've been able to follow up here with answers to your questions.

What I'm confused about is the concept here is to:

Unload the universe JBOSS database so all tables are closed etc.

Then tar up and transfer the archive based on the day/week/month (A rotation).

The script causes a process (uvsh) to run multiple times and the saving of the archive goes to an absolute crawl. The main part of this script is a simple log rotation example.

You can see the process is a gzip but I'm not understanding why uvsh is being called multiple times when the script runs?

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
