there are a few products that people try to compare TSM to; Networker,
Netbackup and CommVault come to mind.
Keep in mind that all of these require full backups at some interval, occupying
much more tape that TSM does. So when presenting alternatives, do not only
consider licensing cost but also the cost of media, servers, network etc. Also
keep in mind that some products are disk to tape only, requiring you to have at
least one tape drive for each concurrent backup/restore session, or implement
expensive VTL solutions while TSM doesn't need one. (The IBM VTS for the
mainframe was running ADSM for a reason!).
Licensing schemes for these products are completely different. While IBM
charges for cpu's, competitors also charge for functionality, such as
archiving? drm? The number of volumes you can manage in a library? The number
of drives? etc. Look into what you need and make sure you have the total
picture.
As a word of advise, make sure that the audit is correct. I've seen IBM try to
charge customers for TDP for databases for DB2, while everybody knows that
there is no such product! If in doubt, challenge the audit results, this might
be worth the effort.
