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.

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?  I have seen a lot of stuff on the market, but I have
also heard where some people have found out later that some of the
technologies don't always work as smoothly as their slated. i.e. one
solution I have seen takes all of your data and compresses it into
block level format on a separate device, but if you want to restore
the data or back it up to tape, you have to first uncompress it to a
readable format and then copy to tape.  

Thanks.
