I'm not a dev, however I use 2Mb block size (this is the largest bacula currently supports) The only downside is that you _must_ mark all active tapes as "used" before changing block size. Bacula will be able to read the old tapes, but it cannot handle maximum block size changing midway through a tape. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
