Hi to you all, We're new to TSM 4.2 and just starting to deploy the client 4.2 for our Windows 2000 servers... We heard that in previous version of TSM client, we could not specify a management class for SYSTEMOBJECT in the include statement. Now, we can with 4.2.... We'd like to hear from others about using this new feature. For example, during a backup, do you refer to a specific management class for SYSTEMOBJECT and if so, how many versions (active, inactive) do you keep? We heard that SYSTEMOBJECT can produce a lot of TSM DB overhead (more than 1500 objects added for each backup everytime even if those objects don't change). Furthermore, we'd like to know how TSM consider SYSTEMOBJECT backup during incrementals... does it treats it like a single object ? (i.e. if only a single file is modified in SYSTEMOBJECT, does TSM take the whole SYSTEMOBJECT again in backup and make the previous SYSTEMOBJECT version inactive... if so, this would indicate that TSM treats SYSTEMOBJECT like a single entity and apply the same logic about making this object active/inactive during incrementals backups). The point here is to use a mgmt class that limits how many versions of SYSTEMOBJECT to keep compared to regular user files... Thanks for taking time to reply to this inquiry. JF Martin CUM
