Oh, there are at least 5 years of remaining holes in the Bacula implementation at the current rate of development, and in 5 years, there certainly will be new ones. However, in this particular case, there are a number of new features in 1.39 that *should* permit proper handling of removable disks in Bacula. > > Best regards, > Henning Holtschneider > -- > LocaNet oHG - http://www.loca.net > Lindemannstrasse 81, D-44137 Dortmund > tel +49 231 91596-25, fax +49 231 91596-55 > sip [EMAIL PROTECTED] > Best regards, Kern _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
