Today, when greatest practices for backup and restoration are extra vital than ever earlier than, it is good to know that high-end absolutely open supply enterprise backup options exist for even the biggest organizations. Perhaps essentially the most highly effective open supply resolution in its class is Bacula, a extremely scalable software program for backup, restoration, and information verification. It is a mature but nonetheless considerably creating venture utilized by MSPs, protection organizations, ISVs, and e-commerce firms worldwide and runs on many alternative Linux flavors. Bacula has a thriving neighborhood, and plenty of Linux fans use it to offer a powerful stage of knowledge safety.
With the various extreme disruptions that ransomware causes right now, it is important that the shopper system being backed up is rarely conscious of storage targets and has no credentials for accessing them. This is true in Bacula’s case, and as well as:
- Storage and Storage Deamon hosts are devoted methods, strictly secured, permitting solely Bacula-related visitors and admin entry and nothing else.
- Bacula’s “Director” (core administration module) is a devoted system with the identical restrictive entry.
Bacula has loads of extra configuration choices to tune backups to person wants. It features in networks and might again up each distant and native hosts. For first-time customers, it will possibly look advanced, however happily, the Bacula Project additionally supplies the Baculum internet interface to ease administration. Many Linux customers are more than pleased to depend on Bacula’s command-line interface to use its appreciable vary of capabilities, however typically it is good to have an efficient GUI, too. That’s the place the open supply Baculum is available in.
Baculum
Baculum’s set up course of in all fairness easy as a result of its repositories present binary packages for common Linux distributions. After set up, you’ve got entry to 2 wizards:
- The Baculum API – a REST API element for working with Bacula information.
- The Baculum Web element – the net interface itself.
The Baculum API is put in on hosts with Bacula elements which you handle from the net interface stage. Baculum Web is often one occasion that connects all Baculum API hosts and makes it potential to handle all of them. This structure matches properly with the Bacula community structure as a result of you may handle all Bacula hosts from one interface. It’s vital to know that the net interface doesn’t retailer any Bacula-specific configuration from any host however manages them by sending API requests as a substitute. When you modify the interface or run Bacula actions, they’re accomplished in real-time. When you click on on the save configuration button, the modification is completed concurrently on the focused hosts.
Below is a pattern Bacula and Baculum topology.

One drawback of this strategy is that it’s worthwhile to set up one Baculum API occasion on every Bacula host that you just wish to handle. If there are lots of servers to again up, it’s potential to automate the set up course of utilizing an application-deployment device like Ansible.
In my case, I’ve a a lot less complicated topology with just one host managed by Baculum. My topology seems to be just like the one under.

You can determine what Bacula assets to share on every Baculum API host. You can set the API hosts to do configuration work, entry the Bacula catalog database, run Bacula console instructions, or any mixture.
After putting in the net interface within the Bacula atmosphere, you see a dashboard web page like this:

Create a backup job
To outline a brand new backup job, go to the job web page to see some wizards for creating backup, copy, or migrate jobs utilizing a customized job type. For this demonstration, I selected the backup job, which shows the primary wizard step:
(Rob Morrison, CC BY-SA 4.0)
First, kind the brand new job identify and non-compulsory description. In the second step, determine what to backup. For this instance, I selected a Bacula shopper and FileSet, which defines the paths to be backed up. Usually, on this window, there are no FileSet choices to select from but, however you may create one with the Add new fileset button within the wizard. To outline paths, I made a decision to browse the shopper filesystem and choose paths within the drag and drop browser, as within the picture under.
(Rob Morrison, CC BY-SA 4.0)
Once the FileSet is prepared, the subsequent step is to pick the place to avoid wasting the backed-up information for this job. Select a storage location and a quantity pool.
(Rob Morrison, CC BY-SA 4.0)
As with FileSets, you’ve got an choice to create a brand new pool. In this instance, I selected an current quantity pool.
In the subsequent step are job-specific choices like selecting the job stage (full, incremental, differential, and many others.), job precedence, and some different settings.
(Rob Morrison, CC BY-SA 4.0)
On the subsequent wizard web page, specify when to run this backup job. Backups are often run periodically, and right here you may select a schedule for this job. If you do not have a schedule, you may create it on this interface:
(Rob Morrison, CC BY-SA 4.0)
The final wizard step is only a abstract of all values chosen within the earlier steps.
(Rob Morrison, CC BY-SA 4.0)
Review all of the values, and if they give the impression of being appropriate, create the brand new job.
Run the backup
OK, you’ve got a brand new backup job. To run the preliminary backup, it’s possible you’ll select to start out it manually utilizing the Run job button. There is a helpful functionality within the Run job window to estimate a job earlier than working it. Run this estimation to know upfront what number of recordsdata and what number of bytes will probably be backed up by this job.
(Rob Morrison, CC BY-SA 4.0)
After working the job, you progress to a job view web page the place you may see backup progress from the shopper’s perspective.

You can observe job standing from three locations on the interface:
- The Bacula shopper (proven above).
- The Bacula director element aspect.
- The storage daemon perspective.
Here you may see the job progress on the director and storage daemon aspect:

The backup job completes.
Restore information
Of course, you could have the ability to restore the backed-up information. Baculum supplies a Restore wizard within the major sidebar menu. After opening it, you see a backup shopper choice to which you’ll restore the info.
(Rob Morrison, CC BY-SA 4.0)
Select the shopper and go to the second step. Here you see all backups from that shopper. Your backup is on the prime, so it’s straightforward to decide on. However, if you wish to discover a previous backup, search the backups information grid. There can be an choice to discover a backup by filename, with or and not using a path.
(Rob Morrison, CC BY-SA 4.0)
Select the backup and go to file choice on the third restore wizard step. Here, within the file browser, select directories and recordsdata to revive. The browser additionally has an space to pick a particular file model if it exists in different backups.
(Rob Morrison, CC BY-SA 4.0)
The subsequent wizard step defines the vacation spot the place the restore will save the info. By default, the shopper from which the backup originates is chosen, however you may change that to revive to a distinct host than the unique. You can even outline an absolute path on the shopper to revive the info. The media required to finish this restore is displayed. This may be very helpful for a backup tape machine operator to arrange for the restore job. Personally, I exploit disk media, and my volumes can be found for the storage daemon on a regular basis.
(Rob Morrison, CC BY-SA 4.0)
The subsequent step provides the restore choices, reminiscent of changing a coverage for current recordsdata on the filesystem or file relocation fields. I preserve them untouched and go to the abstract step earlier than working the restore.
(Rob Morrison, CC BY-SA 4.0)
In the restore job—similar to within the backup job—you see the working restore job’s progress. After completion, there’s a abstract of the complete course of.
(Rob Morrison, CC BY-SA 4.0)
That’s nearly it. The backup and a restore are accomplished. The course of could also be slightly less complicated with different instruments, however Bacula provides Linux fans tons of of very helpful choices. This limits how a lot you may simplify the interface, and most customers of Bacula don’t need that.
Copy jobs
Besides doing conventional backup and restore jobs, Bacula additionally supplies a couple of different job sorts. One of them is Copy job, which copies backups between storage gadgets from one pool of volumes to a different. One storage machine could be a disk, and one other could be a tape or tape library. Copy job reads information from file volumes and sends it to tape gadgets for saving on magnetic tapes. Bacula customers can configure a backup D2D2T technique (disk-to-disk-to-tape). Source and vacation spot storage could be of various sorts (disk and tape), however it works simply as properly when copying backup jobs between the identical machine sorts.
Baculum has full assist for copy jobs, together with configuring copy jobs and ending with restoring information straight from copy jobs. Configure a duplicate job utilizing the copy job wizard seen within the picture under.
(Rob Morrison, CC BY-SA 4.0)
After typing the brand new copy job identify, select the supply storage and supply quantity pool. This is the storage that reads information when the copy job runs.
(Rob Morrison, CC BY-SA 4.0)
The third wizard step specifies learn how to copy jobs. In different phrases, you may outline the choice standards used for selecting the backups that will probably be copied. You can choose backups by patterns like:
- Job identify
- Client
- Volume
- Smallest quantity within the pool
- Oldest quantity within the pool
- SQL question
- Copy all uncopied jobs so removed from the pool
In this instance, I selected a variety by job identify.
(Rob Morrison, CC BY-SA 4.0)
Select the vacation spot storage and pool within the subsequent step. This storage writes backups to the vacation spot pool once you run the copy job.
(Rob Morrison, CC BY-SA 4.0)
In the penultimate step are a few choices, reminiscent of the utmost variety of spawned jobs. You can even set a schedule to run the copy job periodically.
(Rob Morrison, CC BY-SA 4.0)
After saving the wizard, run the copy job in the identical place the place you began the backup job. You can see the reside up to date job log output.

Wrap up
Done! You have carried out a backup job, restored a job, and created a duplicate job.
There are two Baculum features that I feel many people will discover helpful.
First, its easy interface allows the person to manage Bacula from any cell machine. This could be essential for circumstances if you end up outdoors the workplace and any individual from the group sends a textual content message like: “Hey! I accidentally deleted an important report file and need it urgently. Are you able to restore it to my computer?” You may do that restore utilizing a cell phone and the identical wizard steps described above.
The second vital perform is its multi-user interface with a number of authentication strategies (native person, primary authentication, LDAP, and many others.). It allows firm workers to make use of Baculum to backup and restore their very own assets with out requiring entry to every other utilities. You can customise the role-based entry management interface for every group of customers.
Of course, these choices are simply the tip of the iceberg relating to Bacula’s capabilities with Baculum. Baculum actually is about being configurable. I hope you may take pleasure in its advantages and the empowerment it brings you to make your information safer and your life simpler!
