It's fine as it is. 2MB is the maximum allowable in bacula, however you probably won't see much speed improvement past 500kB unless there's compressible data in the train (it's faster, but only a little. I use it because I have tight backup windows and a lot of data to deal with) FWIW Most LTO tape drives have 8MB(IBM) or 16MB(HP) write buffers. ------------------------------------------------------------------------------ Transform Data into Opportunity.
