Backups to the Future: Eliminate Tape Backups with FreeNAS and Bacula
Address = localhost
You also could search for the client.example.com and storage.example.com entries to find some of the other entries that need to be changed. Once the passwords and Address fields have been set, open the /etc/bacula/bacula-sd.conf file in your editor, and comment the following line in the Device section of the Filestorage device:
Archive Device = /tmp
Then, add the line below in its place to associate the locally mounted FreeNAS partition with the storage dæmon so you can back up to it:
Archive Device = /mnt/freenas
The final step is to open the Services utility under System→Administration, and check the box to set bacula-dir, bacula-sd and bacula-fd to start on runlevel 5 (Figure 5). You now can use the syntax:
service bacula-dir|sd|fd start|stop|restart
to control the dæmons. On other distributions, you can start the dæmons directly from /usr/sbin and use chkconfig to set the runlevel.
Running a backup is quite simple, as you already have done most of the work by editing the bacula-dir.conf file. Start the Bacula console from the Applications→System Tools Menu (Figure 6) in GNOME. You may need to edit the launcher, as I did, to point it to the correct /etc/bacula/gnome-console.conf file. Start the Tray Monitor utility from the System Tools menu as well. The Tray Monitor (Figure 7) is nice, because it gives you a quick glance at the status of the dæmons and any running jobs. This is helpful when you are multitasking or have jobs that run nightly and you want to check their status the next morning. Return to the console, and click the Run button to bring up the backup job dialog window. Under job, select WeeklyHomeBackups (Figure 8). This pre-fills the field selections with the items specified in your .conf file. You could change any of these options at this point, but they must first exist in the .conf file or they will not appear in the fields. In other words, you can't create a job from the drop-downs without populating the Job section of the .conf file.
Up to this point, there are no volumes, which as previously mentioned, need to exist before you can run a backup. Typically, you would have to use the label command from the console's command line to create a volume in a pool manually, but because of our settings, the system will create them automatically, auto-name them and recycle them when the volume retention period triggers. I like this better than manually creating the volumes, as you are less likely to encounter naming errors. Click OK to run the job, and view the results in the console.
If you were to change the Volume Retention setting on the same pool, restart the dæmons and run the job again, you would see the system auto-recycle a volume in the pool for the next job. Otherwise, it will prompt you to create a new volume, as no existing volumes can be recycled due to retention settings. You can run these jobs manually as often as you want, but they also will run according to the schedule defined in the bacula-dir.conf file.
Restoring a file in Bacula also is remarkably simple. You can use either the Restore button on the console toolbar or the restore command. Both are easy to use, but the restore command provides more options. To keep it simple, let's use the Restore button. When the dialog opens, select a job, client, pool and so on from which to restore (Figure 9), then click Select Files to mark the files/folders you want to restore (Figure 10). Before the restore job runs, you will be prompted to confirm your options, at which point you could type yes, mod or no. Typing mod provides more options over the job, including the option to restore to a different path from the original one.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
