And if _anything_ goes wrong you'll have to start over - for a run time of around 21 days assuming best speed. Break the job up into smaller sets. We try to use maximum units of 1Tb. > After that I want to just do > incrementals against the initial Full Backup; the files will never > change, they will just be added to as time moves on. You will still want periodic fulls or synthetic fulls. Only having 1 backup is asking for trouble, especially if there are hundreds of subsequent incrementals to spool through too. That's why GFS (grandfather-father-son) backup strategies were developed - there are always at least 2 full backups available in case one set goes bad. > So, I guess a have a couple basic questions.

Yes. If you have multiple tape drives you can also copy between tapes. > Also, do I need to manually "label" the tapes (electronically) as I load > them, or will the fact that the autoloader automatically reads the new > barcodes be enough? look up the "label barcodes" directive. ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
