Netbackup VS. Tivoli

[JStaniec]

We are trying to decide between the two...any opinons? We are going to back up EMC Symmetrix on to HP-UX Server..

Thanks.

We are currently using Veritas NBU on AIX to backup a mixed Intel/Unix environment of about 200 clients. Most of our int'l offices are using TSM on AIX/W2K however, and there has been much discussion for us to switch. The PRIME factor to consider is the differences between the standard GFS backup rotation method that NBU uses, and the "file revision incremental" method Tivoli uses. TSM certainly backs up faster because it is backing up to Disk, and backs up alot less data, as it is only doing INC backups, and its only storing 2 file revisions by default (the more you want to keep the more hardware you need). This is very different than a GFS retention, where you have ALOT more by default (7dailys+4weeklies+12monthlies=23 sets of restorable data). It is this difference in data storage that is why we like TSM in IT (saves money!) but is also why the Business doesn't (can't restore from 6 months ago) and so long as the Business pays the bills, they call the shots.

Thanks...we do have Oracle and want to do daily HOT backups and weekend COLD backups. We will use a STK or IBM LTO tape drive with 100GB/200Gb tapes.

We looked at TSM and NBU and as I see it you are 100% right on the difference.
Personaly I want to take FULL backups always. It's much more simple to handle especialy when you have to restore/recover a system or a server.

That backups to disk should be faster depends mostly on your tapehardware. We use STK9940B's and I don't know of a disksystem that can take data at that speed in the long run.

By the way STK don't produce LTO drives, but they sell IBM's and other vendors drives.

I have never used LTO but from what people tell me they say that the IBM LTO drives are the best.

LTO is a very very good mid range tape format (as I see it)

I'm familiar with both products and have been using TSM in particular for years. The above statements are rather misleading.. there is nothing to prevent you from retaining data for as long as you want using TSM. To say keeping more revisions requires more hardware is similiarly misleading. No additional hardware is required at all, you just need more media to store it all just like any backup product. In fact it's quite possible and probable that you can retain *ALL* your data back to the date you're interested in and still use less media then doing that with netbackup because it manages your media far better.
