Hi TSM Admins. There has been some time since i posted a message there so I'm not up to speed on the talk, but i made a search on this topic and found nothing but old news, witch do not apply here.
First of I want to say i have been involved with selling and installing TSM for since TSM 3.7 and this is the first time i see a threat from the competitors. Veritas synthetic backup with disk solution brings similar solution to customers as TSM Progressive Incremental backup. First of there is no Network traffic since veritas can make a new full backup from the old full backup and all the incremental4s go to disk. second they claim they can use Tape Drives more effectively. This has rased questions witch i can4t answer since i have no Veritas Background. And i am hoping that someone has answer to these questions. How does this scale? - Do I need extra drives in my library to handle the creation of the synthetic full tapes? - Do I need extra tapes? How often can I make a synthetic full - Is this only recommended on a weekly basis? How do I make a point in time restore to a point between to synthetic fulls? How much overhead of files should I expect for creating the synthetic fulls? Can I collocate data so data to a given client is not scattered on several tapes? Can I restart a restore of a large file if the connection fails or do I have to restart the restore of that specific file? If I decide to change my policies - How does that affect the data that has already been backed up? What happens when tapes contain mostly wasted space due to expired data? I rely need answer's to these questions. since need to make a potential customer understand the difference here.
