Re: [Networker] EMC/Legato-NetWorker vs Veritas-NetBackup

Well,
As one person remarked, it was TSM I was thinking of when I remarked
that there was a backup software package that prided itself on this
concept of infinite incrementals or some such thing. A google search on
TSM shows the following as the first hit:
IBM *Tivoli* *Storage* *Manager* - Product overview
<http://www.ibm.com/software/tivoli/products/storage-mgr/>
(http://www-306.ibm.com/software/tivoli/products/storage-mgr/)
wherein it mentions as one advantage:
"Intelligent backups and restores utilizing a revolutionary progressive
incremental backup and restore strategy, where only new and used files
are backed up"
Not sure if I like that approach or not. Should I like that? Why does
that make me nervous??? Can anyone attest to this feature being good or
bad? Has anyone played with this, or can you defend or aver this type of
feature? Sounds suspect to me. After all, won't you end up with a ton of
tapes to do recovers unless they conglomerate backups? Hmm ...

OK, so NetBackup and Networker both suck. :) How about TSM then? In
particular, platform support, sharing of media between storage nodes,
price, support, and NDMP support (ie no dedicated drive or extra software
or any of that crap). I know this has been brought up before, and might
seem a bit off-topic but I think many of us are interested to know, since
its not easy to find a fairly non-biased opinion on this topic.
