Looking for something that would preview the amount of data if I ran an INCREMENTAL on the currently defined DOMAIN on the client. Preview just gives me what would be included/excluded based on the filespec specified and the current include/exclude list. I don't think this is really what they want to do as it includes the whole filespace information from the TSM server to compare/build lists. Been thinking about using -INCRBYDATE on the systems that really don't qualify for a journal and also SKIPNTPERMISSIONS to take that out of the equation.
Unless I configure them for the journal and use the unsupported utilities to list out the journal and maybe massage it with Perl or something. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Richard Sims Sent: Tuesday, January 19, 2010 2:12 PM To: ADSM-L@VM.MARIST.EDU Subject: Re: Estimating backups On Jan 19, 2010, at 1:17 PM, Bill Boyer wrote: > Is there a feature or tool available that you can run against a server and > get an estimate on how much data will be backed up? ...

An in-client preview can't tell you how long a networked backup is going to take or gauge the effects of a large Incremental contending for memory with other apps in the client system, where paging can cripple a backup. I'd advise performing analysis to identify the slowest ingredients in your backups and see if they can be addressed. Exploration of journal-based backups or target area backups may be in order.
