It’s been many years since I looked
at it closely, but when we did it, locking the VOB, then backing up normally,
then unlocking, was sufficient for consistent backups.
The vob is completely read only while it’s
locked. This is covered in the Clearcase administration manuals.
Clearcase “View” storage was
an entirely different matter – basically restoring a view was an
unsupported operation – although you could usually pull out individual
files and manually copy them into a new view if you had to. As I understand it,
backing up and restoring views was supposedly not required, as everything
should be in the VOB. But that assumed you’re developers weren’t
using “view private” files extensively. J
The biggest issue we ever had was
performance – the VOB is many small files, and a normal filesystem backup
struggles with that.
I’d also recommend doing full
backups every time on VOB’s, rather than incrementals, as a mistake
merging incremental backups (ie, restoring deleted files), can result in a bad
VOB.

Tristan.
What
is the best way to backup Clear Case Infrastructure?
We
have 2 servers running Aix 5.1 with Oracle 10g on the db server.
We
want to use Netbackup 6.5 but can’t find an agent for the clearcase db
(proprietary db).
Just
looking for some insight from others.
thanks
