The rpms should follow shortly (probably this weekend). + +If you are currently using 2.4.4, please note that within a few months that +version will no longer be supported, so please consider the possibility of +upgrading. + +This release probably has the most new features that we have ever released, +and it has taken a long time to produce it. The basic code is very well +tested, and if you stick to 2.4.4 features, you are unlikely to experience +problems. However, many of the new features have not been well tested, so +your help will be appreciated. + +The following issues with 3.0.0 are known and we are working on them: + +1. The documentation is not 100% complete (there are so many new features that +we missed documenting some). + +2. All the new documentation is in the New Features chapter, but not all of it +has yet been integrated back into the appropriate chapters. + +3. James has reported that the Exchange plugin may crash if you cancel a job +while it is running. He is working on this. + +4. The SD has many new features that will make it more stable. One in +particular is that it knows what Volumes will be read during a migration, +copy, or Virtual backup job, and will ensure that they are not selected for +writing (something easy to do if you are using disk files and the same pool +for reading an writing). However, the day after the release was cut, I found +a problem with this code that prevents it from working properly during +certain pre-allocations of the write tape. + +5. There is still an outstanding bug report on VSS failing (it seems to be a +bit of a rare case). + +As I previously announced, we will now make 3.0.0 our main release source code +stream, and we hope to release new version every six months and bug fix +updates even sooner. To be able to do this, we will support version 2.4.4 +only for a few more months. There after the project will only support the +most current release ... + +This release comprises a lot of work by a lot of different people and many +contributions.

In other words, you should +not have to upgrade all your File daemons when you upgrade. However, any +release of version 2.5.40 or greater requires a database upgrade. + +================== Warning !!!!!! ========================== + +New Catalog format in version 3.0.0 (2.5.40 or later) +----------------------------------------------------- + +This release of Bacula uses a new catalog format. We provide a set of +scripts that permit to convert a 2.4.x (version 10) catalog to 3.0.0 (version +11). The Bacula project rpms distributed on Source Forge will automatically +detect the database change and do the upgrade for you. We strongly +recommend that you save a copy of your existing database before upgrading +using rpms. + +The simplest way to upgrad the database assuming you are building from +source: +1. Stop any current version of Bacula from running. +2. Save a copy of your existing database. +3. Configure, build, and install the 3.0.0 version of Bacula + Note the new ./configure options in the manuals see the link + at the bottom of this file. +4. cd +5. ./update_bacula_tables +6. If you have multiple catalogs, edit the update_bacula_tables + script and put the name of another database, and then + execute the script again. Repeat this until all Bacula + catalogs have been updated. +7. Start the new Bacula. If everything worked, it should + not print any error messages. + +The upgrade operation will convert the FileId index field of the File table +from 32 bits to 64 bits. This operation will take TIME and will *temporarily* +DOUBLE THE SIZE of your catalog. Bacula must be shutdown during this update, +so, won't be able to run jobs during this period. For example, a 3 million +files +catalog will take 2 mins to upgrade on a normal machine. Don't forget to +backup it before executing the script. + +If you start from scratch, you don't need to run the update_bacula_tables +script because the create_bacula_tables script automatically creates the new +table format. However, if you are using a version of Bacula older than 2.5.40 +(e.g. 2.4.4) then you need to run the update_bacula_tables script that will +be found in the /src/cats directory after you run the ./configure +command. As mentioned above, before running this script, please backup your +catalog database, and when you do running it, be sure shutdown Bacula and be +aware that running the script can take some time depending on your database +size. + + +Important New configure options : +---------------------- + +This release of Bacula 3.0.0 uses libtool by default +to generate the Bacula libraries as shared objects rather than +being directly linked in as in prior versions. This means that +the Bacula shared objects, must either be in a shared object +directory known to the loader or they must be in the directory +where the Bacula binaries are installed. It is also possible +to explicitly specify the libraries directory on the ./configure +line (--libdir=/full-path/dir), but this should not be necessary. + + ./configure --libdir= + +If you have problems with libtool or you wish to use the old +way of building libraries and linking them into Bacula, you +can do so by disabling libtool on the configure command line with: + + ./configure --disable-libtool + +During the installation of Bacula 3.0.0, it will now install +bat help files (if you have configured bat). These files +are placed in /usr/share/doc/bacula/html by default. If you +want to put them elsewhere use: + + ./configure --htmldir= + +During the installation of Bacula, it will now install the +ReleaseNotes, License, technotes, ChangeLog, and similar +files in /usr/share/doc/bacula by default. If you +want to put them elsewhere use: + + ./configure --docdir= + +During the installation of Bacula, any plugins will be +installed in the plugindir, which is by default the +same as libdir (/usr/lib). You can specify an alternate +location with: + + ./configure --with-plugindir= + +============================================================== + +This release includes large number of new features and changes. +It should be more or less compatible with previous xx.conf files +and File daemons providing that you are not using any of the new +features. + +Please see the New Features chapter of the new manual, which documents +some but not all the new features (we are still working on it): + +http://www.bacula.org/manuals/en/concepts/concepts/New_Features.html + +The ChangeLog has more details. + +;;; Kern;;;03 Nobember 2008 at 17:35 Critical 2.4.3-orphaned-jobs.patch released We recently found and corrected a serious bug in Bacula that causes jobs to be
