The components include the director, catalog, storage daemon, and client, serving different functions. The structure of Bacula architecture consists of different interacting features.
All of these features employ TCP sockets in their communication across all network connections. This type of architecture manages backups of s of workloads across different continents. The communication architecture of Amanda operates around TLS 1. Amanda Enterprise Architecture Image reference: Source. Due to a wide range of plugins, high-end databases, and ERP systems, Bacula enables easy backup of different infrastructure types, including virtual infrastructure.
Additionally, optimization and automation through Bacula bring certain agility and security in the operations. On the other hand, even though Amanda has an intelligent scheduler and plugin framework, running it on Windows is more complicated than Ubuntu and Linux. It also supports volume shadow copy service VSS in Windows to back up open files. Looking at the scalability and flexibility, Bacula scores over Amanda.
It enables two or more separate Storage daemons to share the same physical tape device. Its key benefits include:. Bacula SAN tape library module. Image reference: Source. And yet, they are powerful enough to comply with rigorous disaster recovery requirements.
The most prominent feature of Amanda for storing backups is its holding disk, which works as a staging area. They also offer reliable protection for massive amounts of data, along with large-scale automated NAS cloud backup. Eventually, this enables fast, reliable backup and recovery for unstructured datasets. Bacula consists of a powerful GUI that makes it highly user-friendly. Besides that, its shell administrative interface allows admins to work with SSH even remotely. However, the Bacula test environment only contains a single drive, which can hinder enterprise-level requirements as they involve handling multiple libraries.
Also, sometimes a kernel memory leak bug could arise amidst the data flight if not paused while de-spooling it to the tape. This enables you to configure multiple backups without writing one after another. Looking at the storage capacity, Amanda scores over Bacula. Bacula administration tool BAT is a feature-rich graphic user-interface tool. GUI of Bacula is pretty convenient even for the less-experienced users as they can effectively administer and monitor it. For experienced users, it provides many extra features, such as configuring, monitoring, and statistics.
For larger deployments, Bacula has a comprehensive web-based GUI management suite. Amanda backs up all the systems over the network in parallel using encryption with OpenSSH on request. Administrators can also run their own scripts before and after backups. Further, Bacula can be deployed in multiple scenarios owing to its BWEB feature, enabling an intuitive configuration. This makes it a highly effective software for controlling and monitoring how the components interact with each other.
Whereas Amanda enables the administrators to retain their backed-up files with its archiving function. So, if an earlier backup image expires, admins can reuse the tape for new backups. Even if the configuration is set not to reuse the tapes, certain tapes can be reused as archives. Looking at the centralized admin support, even though Amanda provides archiving options, Bacula has better and flexible interaction with the administrators.
The bscan program in Bacula can scan large backup volumes and easily reproduce the catalog database. It is also capable of restoring this database by utilizing the earlier saved bootstrap files. Bacula has its tools: extract and a standalone bis program for converting and listing files. Additionally, its comprehensive SQL database enables online file-viewing on any volume, easing the reporting processes.
Amanda eases the monitoring and reporting processes by sending out reports of each backup through emails. It uses the Zmanda Management Console for recovery, wherein admins can determine which data needs restoration and where exactly. Amanda was designed especially for tape drives. Its tape spanning feature enables the dumps to span from one volume and back up the data sets from any environment.
For this, Amanda follows a planned roadmap before starting a dump run. This eventually makes it easier to estimate the volume of dumped data, resulting in a consistent flow of backups. Unlike Amanda, Bacula comes with an in-built scheduler. It allows better flexibility to set up different schedules.
Moreover, admins can also run specific scripts like Bash, Python, Perl — both before and after a backup. Bacula also comes with an assistant that guides you through backing up a system after installing the OS-specific daemon. When we look at the functionalities provided by each software, both follow a step-by-step guide to take you through all the operations. However, Amanda also offers more controls that you can apply for each backup level. Instead of using proprietary tools, Amanda utilizes tar, dump, or Schilly tar for backup tools.
As a result, in this case, Amanda scores over Bacula. For each one of its verified and backed-up files, Bacula implements a checksum calculation for restoring purposes. And for encrypting connections between file daemons, it utilizes TLS for ensuring restoration of all attributes of a file. Bacula has an automated recovery system for Linux and Solaris systems, starting from the bare metal. Bacula works on the continuous data protection CDP model, also known as a real-time backup.
With CDP, it can automatically save a copy of every change made to the data. Essentially, it means Bacula easily captures each version of the data saved by the user. Amanda has an organized process for backup admins based on roles.
Amanda fetch the archives created by NTBackup through Samba restricted-hidden share For the Windows servers, might not be the best solution, but it works for us I just like the way truecrypt works and was using it before I started using Cobian. Truecrypt encrypts the disk or part of the disk rather than encrypting individual files. That means I can have other things on the disk that are protected by the encryption, not just the backups. If the device is removed from the system, it is is still encrypted because the data is never in an unencrypted form on the actual disk.
John , we currently use a combination of both Windows file synchronization and backuppc backups. However, with notebooks in particular, i do not have backuppc backing them up directly, as to me, it seems like a redundant function redundant data transfers across the network, redundant data storage requirements, redundant configurations, redundant trouble-shooting when issues arise, et cetera.
So, what we tend to do, for notebooks in particular, is to have them synchronize "network" files using Windows file synchronization, to a network share, then to have BackupPC backup the network share s containing all of the user data. This minimizes work for us, in that when notebooks are added to the network no additional backup configurations need to be done, as BackupPC already hits the root of the network share. One problem with the file synchronization issue for notebooks has been mentioned elsewhere in the Spiceworks Community is when notebooks are "offline" or out of their networks for extended periods of time.
And, as was mentioned elsewhere, when such is to be the case, then other backup methods should be available, such as external hard disk drives, or online backup solutions for specific "mobile" devices. And both tank your bandwidth if going over the WAN. To continue this discussion, please ask a new question. Get answers from your peers along with millions of IT pros who visit Spiceworks.
It looks pretty promising from the things I've read on the web. Popular Topics in Data Backup. So, without any proper recovery solution, it might take days or even weeks to repair the damage. Here, we gathered a list of best open source backup software for server those can back up single system to hundreds, bare metal recovery, comes with encryption and compression utilities.
These are highly scalable and can prove a complete backup and recovery solution to an enterprise. Bacula is an enterprise grid but open source backup software that gives a complete backup solution.
It offers two versions one is enterprise and another one is community edition. First, give a hit to its community edition which offers pretty much great basic features those need to start.
It allows managing backup, recovery, and verification of computer data across a network of computers of different kinds. Amanda Advanced Maryland Automatic Network Disk Archiver is another enterprise grade open source backup and recovery software.
The Amanda comes in three editions Amanda Community Edition which is free to download and use, Amanda Enterprise Edition that provides support for backing up live applications and databases and Zmanda Backup Appliance, a pre-configured virtual machine to backup an entire network of systems and applications. This open source backup software runs on an entire single computer and can backup different type of media including tape and disk.
The Bareos allows IT admins to manage backup, recovery, and verification of computer data across a network of computers of different kinds just like Bacula. Clonezilla is bare metal open-source backup and recovery software.
Basically, it is a backup solution that imaging or cloning entire partition and disk. If you planning to backup and restore a single machine then the Clonezilla Live is the suitable option while for massive server backup and restore the Clonezilla server edition is the one. It can clone 40 computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the cloning efficiency. The best part is the both open source version of this backup software are the free and open source.
Duplicati is a Free and open source online backup software that also free for commercial purpose. IT designed to create backups online from scratch and also handles network issues very intelligently.
For example, during backup any network interruption happens, it will pause the backup and resume from where it dropped it. Also, it checks the content of backups regularly.
