Re: [Veritas-bu] VTL Recommendations
Remember that NB built in dedup has a size limit. For NetBackup 7.0, the maximum deduplication capacity is 32 TBs. -Original Message- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of A Darren Dunham Sent: Thursday, September 30, 2010 12:32 PM To: VERITAS-BU@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] VTL Recommendations On Tue, Sep 28, 2010 at 06:24:59PM -0400, mitch808 wrote: As others mentioned, just step away from VTL's in general.

[Veritas-bu] VTL Recommendations
As others mentioned, just step away from VTL's in general. All they are, are disk as the base, with software on top, emulating tape, with a big markup for that software. Just buy plain disk, or re-use disk you may already have, and backup to disk. Add in deduplication that is native now in NBU7, and you have a great combination that is affordable and eliminates a lot of complexity of a black box. SLP's can then help you duplicate to another media server/site/or physical tape. +-- |This was sent by mnab...@gmail.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +-- ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
Re: [Veritas-bu] VTL Recommendations
I would recommend moving away from the Virtual Tape Library and utilizing Advanced Disk, Disk Pools and Storage LifeCycle Policies. Most VTLs today can be utilized as a giant pool of disks, instead of a bunch of fake tape drives, as well. But, at that point, you could remove the complication of a VTL and just use a disk array on the backend. Rusty Major, MCSE, BCFP, VCS ▪ Sr. Storage Engineer ▪ SunGard Availability Services ▪ 757 N.

We currently have Copan and NetApp VTL. NetApp disbanded their VTL practice so moving forward support will be an issue. Copan is and has been running well, we are just looking into alternatives, if it makes sense. Any suggestions? Thank you for your feedback in advance.

Re: [Veritas-bu] VTL Recommendations
The VTL interface has been superseded by OST based devices and NetBackup's own disk staging technologies. If I were to start again I would take a serious look at the disk and deduplication options available in NetBackup's 7.x. NetBackup 7.x now converges three technologies: 1/ deduplication at client 2/ deduplication at media server 3/ deduplication at disk target This convergence is tightly integrated across the NetBackup suite. Once you start introducing a mix of technologies in the backup data path the solution because less efficient.
