Does anyone out there have experience with the Database Edition for Oracle
and Block Level Incremental Backups?
BTW, I'm running NetBackup 34_3 and dbed 3.0.

When a "standard" backup stream encounters a tape write failure, it has the
ability to retry (and usually succeed).

When a BLIB backup stream encounters a tape write failure it renders the
entire backup a failure even though the other n streams are all completing
successfully.  The only recourse is to clean up the mess and restart the
entire backup.  This is very frustrating when you're several hours into a
large database backup.

I'd be interested in hearing from folks that are using BLIBs and what
results they're getting.  Is there a later version of NetBackup/dbed that is
tolerant of tape write errors?

I'd also like to know what is a "normal" number of tape write failures on an
L700.  Is this a frequent occurrence?

dave.
