Re: [Veritas-bu] Virtual Tape library or backup to disk
Good day Dan, My personal recommendation would be to stay away from any VTL and rather use the DISK to DISK to tape feature which is part of version 6 of NetBackup and even stronger in 6.1. The Veritas (Symantec API) has been released and is currently being included in most of the hardware vendors. See the attached link. The one thing that really has me worried is that VTL's emulate a library and tapes and are subject to those rules. There is also an issue as far as compressing is concerned as this is generally done by the VTL's operating system and slows down your backups dramatically. Many other rules change as VTL's generally require a single stream per tape. You are also liable to pay for tape drive licenses etc. http://searchstorage.techtarget.com/originalContent/0,289142,sid5_gci1 229879,00.html Regards, Clem Kruger From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sixbury, Dan Sent: 11 April 2007 16:04 PM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] Virtual Tape library or backup to disk Does anyone have any recommendations in regards to VTLs or disk pools, etc. for backup?

Re: [Veritas-bu] Virtual Tape library or backup to disk
I recently spent several months looking at disk technologies. Just generally speaking here I found that Disk Based Backups (DSU/DSSUs) are pretty young in Netbackup and there's quite a few issues that have to be monitored and maintained to make them work correctly. That aside, you can't beat the price per GB/TB for raw disk storage versus a VTL. From a management perspective, VTLs I think are easier because media management is so well defined in Netbackup. I've got several Perl scripts I use to manage my DSSUs but everything I need for media is right there in the GUI. As far as compression and block level conversion to different formats etc I think you may be getting a few crossed signals. I've heard quite a few issues with older VTLs especially when people try and duplicate their tapes onto VTLs. I'd check with your hardware vendor, but as best I can tell all those issues were on the bleeding edge. -Jonathan From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sixbury, Dan Sent: Wednesday, April 11, 2007 10:04 AM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] Virtual Tape library or backup to disk Does anyone have any recommendations in regards to VTLs or disk pools, etc. for backup?

Re: [Veritas-bu] Virtual Tape Library
Actually, in 5.x, VTL licensing for specific vendors was also based on TB, migrating away from legacy per drive methodology. [EMAIL PROTECTED] 3/23/2006 7:43 am NetBackup 5.n was licenced by tape drives. NetBackup 6.n is licenced by TB in the VTL. I don't know the detail, e.g. is that raw TB etc. I also don't know if they changed the licencing for 5.n, or if it is still needing drive licences.

RE: [Veritas-bu] Virtual Tape Library
The NetBackup Virtual tape option was originally priced in tiers with so many TB per tier. That pricing was simplified to a price per TB. NBU does not charge by the number of virtual drives since you can have hundreds of virtual drives for relatively small amounts of disk storage.

RE: [Veritas-bu] virtual tape library vs disk storage unit
Hi. You can use storage in a VTL in an SSO fashion , which means you can share storage amoung various Media servers. If you use it as a DSU ( or DSSU) you cannot share the space amoung servers unless you have some kind of common filesystem sharing system.
