I would highly recommend using a versioning tool such as CVS for change control 
. This only stores the delta's between versions making it much more efficient 
in terms of storage . We use it in our software house , the backend is based on 
MySql which we dump to file each night ( after doing a DB check) we then use 
TSM to back it up keeping 3 most current versions of the file and with a delete 
retention of 90 days , the same as we have for all other files (Corporate 
standard ).
This allows the developers to implement their own number of versions and trees 
on a project by project basis , and the systems guys less headaches trying to 
keep everyone happy .

Hi,

We are currently implementing Tivoli as our backup soltuion for all our AIX and 
Windows servers. As far as versioning, is there some sort of guideline most 
people are using as far as number of verisons of a specific file to keep ? We 
are primarily a software production house and I'm trying  to figure out what is 
the mose useful versioning route to go by.

Rich
